Frequently Asked Questions

Koabit is a free household management app available on iOS and Android, designed to simplify daily life for people sharing a home. It brings together in one place all the tools you need to live well together:

Collaborative tasks: create and distribute chores among household members. Each task earns points based on its difficulty, allowing you to track everyone's contribution through a real-time ranking. The most active member wins the Golden Broom 🏆, a virtual trophy that makes housework more fun.

Shared expenses: record shared expenses and let Koabit automatically calculate who owes what to whom. Four splitting modes are available (equal shares, percentage, fixed amount, weighted shares). You can scan your receipts using AI to save time, and manage expenses in multiple currencies.

Shared calendar: centralize all household events in a common calendar. Import your Google, Outlook, or Apple calendars to see everything in one place, and export the Koabit calendar to your usual apps.

Shared lists: create shopping lists, to-do lists, or any other type of list and share them with household members. Everything syncs in real time: when someone checks off an item at the store, everyone sees it instantly.

Statistics: visualize the distribution of tasks and expenses through detailed charts. Track progress by week or month to make sure efforts and costs are shared fairly.

Mood journal: each member can log their daily mood and track their well-being over time. A simple tool to take care of yourself and stay attentive to others.

Whether you're a couple, in a shared flat, a family, or on group holidays, Koabit helps you get better organized, share the workload fairly, and avoid the tensions that come with managing daily life.

Yes, Koabit is 100% free, with no ads, no subscriptions, and no in-app purchases. All features are available as soon as you create your account, with no limitations whatsoever: number of households, members, tasks, or expenses.

Koabit adapts to many everyday situations:

• In a shared flat: distribute chores fairly, track shared expenses (rent, groceries, cleaning) and avoid conflicts
• As a couple: organize the mental load together, share a calendar, and manage the household budget
• As a family: get the kids involved in chores, plan activities, and centralize shopping
• On group holidays: split trip costs (accommodation, restaurants, activities) and see at a glance who owes what to whom
• Among friends for an event: manage expenses for a weekend trip, a birthday, or a holiday

Yes, partially. Koabit uses a local cache system that stores previously loaded data on your device. This means you can view your tasks, expenses, calendar, and lists even without an internet connection.

You can also create or edit tasks, expenses, events, and list items offline. These changes are saved locally and automatically synced once your internet connection is restored. An indicator shows you how many actions are waiting to be synced.

However, some actions such as deleting items or scanning receipts require an active connection.

It's very simple and takes less than a minute:

1. Create your Koabit account (email or sign in with Google/Apple)
2. From the home screen, tap "Create a household" and give it a name (e.g., "Apartment on Main Street")
3. Your household is created! To invite members, go to Profile → Invite Users. There you'll find a unique invitation code to share by message, email, or in person
4. Invited people just need to download Koabit, create their account, then tap "Join a household" and enter the code

Each household member immediately has access to all shared data: tasks, expenses, calendar, and lists.

If someone has invited you to join their household, here's how:

1. Download Koabit from the App Store or Google Play
2. Create your account (email, Google, or Apple)
3. From the home screen, tap "Join a household"
4. Enter the invitation code that was shared with you

By default, you'll get direct access to the household and all its data (tasks, expenses, calendar, lists). However, if the household creator has enabled the "New member approval" option, your request will need to be approved by an existing member before you can access the household.

In Koabit, it's important to distinguish between the two concepts:

• A user is a person who has created a Koabit account and uses the app on their phone. They sign in, interact with the household, and receive notifications.
• A member is part of the household but is not necessarily linked to a user account. This is called a self-managed member.

This allows you to add, for example, a young child or a person who doesn't use a smartphone as a household member, so they can be included in expense splitting or assigned tasks, without needing to download the app. Self-managed members are managed by the other users in the household.

To add a member (whether they have a Koabit account or not), go to Profile → Edit Members → Add a New Member. You can then create a self-managed member by simply giving them a first name. This new member will appear in the household member list and can be assigned tasks, included in shared expenses, etc. If this person creates a Koabit account later, you can link their user profile to this member.

To remove a user (a person with a Koabit account), go to Profile → Edit Members. Next to each member's name, you'll find a button to unlink them from the household. Tap it and confirm. The user will immediately lose access to the household and its shared data. Their Koabit account is not deleted: they can still join other households.

If this user had an unsettled balance (debts or credits), their profile will remain visible on the expense balance screen marked as "Removed" until the balance is settled. Past transactions they participated in are kept in the history.

To delete a member (including a self-managed member), go to Profile → Edit Members and tap the delete button next to their name.

Koabit automatically checks several things before deletion:

• If the member is linked to scheduled expenses (recurring), the deletion is blocked. You'll need to modify or delete those scheduled expenses first.
• If the member has a non-zero balance (they owe money or are owed money), deletion is possible but their financial data is preserved. They will continue to appear on the balance screen marked as "Removed" and their balance can still be settled by other members.
• If the member has no history (no expenses, no completed tasks), they are permanently deleted from the household.

In all cases, the history of tasks and transactions the member participated in is always preserved.

Yes, you can create or join multiple households with the same account. This is handy if, for example, you have one household for your flat share and another for a trip with friends. You can switch between them with a single tap from the home screen. Each household is completely independent: its members, tasks, expenses, and calendar are its own.

To leave a household, go to Profile → Settings → Leave Household. Your past contributions (completed tasks, recorded expenses) will remain visible to other members but will no longer be linked to your active account. If you are the last member of the household, it will be permanently deleted along with all its data.

By default, anyone with the invitation code can join your household directly. If you want to manually approve each new member, go to Profile → Edit Household → Edit Home, then uncheck the "Automatic approval of new members" option. Once this option is disabled, each membership request will need to be approved by an existing household member before the person can access it.

Each task earns points based on its difficulty, which you set freely. For example, you might assign 5 points for "unloading the dishwasher," 15 points for "vacuuming," and 25 points for "cleaning the bathroom." When a member marks a task as done, the points are automatically added to their score.

The household ranking updates in real time, and everyone can see their progress in the Statistics tab. It's a fun and transparent way to make sure the workload is shared fairly.

The Golden Broom 🏆 is a virtual trophy awarded to the household member who has accumulated the most points over a given period. It's a fun way to recognize everyone's contribution and encourage participation. The winner is displayed on the dashboard and in the household statistics. The ranking period (week, month, etc.) can be configured by the household.

To edit an existing task, tap on it to open its details, then tap the edit icon (pencil). You can also swipe the task to the right to reveal the edit button. You can then change the name, category, points, assigned members, recurrence, and scheduled date. Changes are saved immediately.

Note: tasks that have already been marked as done can no longer be edited.

Yes! When creating a task, enable the "Recurrence" option and choose the frequency: daily, weekly, monthly, or a custom interval (e.g., every 3 days). The task will be automatically recreated according to the defined schedule.

This is ideal for regular chores: taking out the bins on Tuesday, vacuuming every week, cleaning the fridge once a month, etc. You can also set a default day and assigned member for each occurrence.

Yes, when creating or editing a task, you can select one or more members of the household. The task will appear in each assigned person's list. You can also leave a task unassigned: it will be visible to everyone and anyone can take it on, which is handy for "first come, first served" tasks.

The Statistics tab gives you a complete overview of task distribution. You'll find:

• The member ranking by points for the period
• The percentage breakdown of the workload
• The task history completed by each member
• The number of tasks completed by category

It's an excellent tool to objectively assess the workload and start a discussion in the household if needed.

Yes! Koabit lets you create, edit, and delete your own task categories. For each category, you can choose an emoji and a name. Go to Tasks → Settings → Categories to manage them.

Categories are used to filter and sort your tasks, and to view the breakdown by category in the statistics. Default categories are provided when the household is created, but you're free to customize them to suit your needs.

Go to Calendar → Settings → Imported Calendars → Add. Paste the ICS URL of your external calendar. To find it:

• Google Calendar: Calendar settings → Integrate calendar → Public address in iCal format
• Outlook: Settings → Shared calendar → Publish a calendar → ICS link
• Apple Calendar: Right-click on the calendar → Share Calendar → check Public Calendar

Koabit then automatically syncs your events. You can import multiple calendars and assign them different colors to easily distinguish them in the shared view.

Yes! Koabit generates an ICS link for your shared calendar that you can add to Google Calendar, Outlook, Apple Calendar, or any compatible app. Go to Calendar → Settings → Export to get your link. This way, events created in Koabit will appear directly in your regular calendar.

No, the Koabit calendar is a complementary shared calendar dedicated to household life. It lets you see in one place the events of all members: appointments, outings, reminders, scheduled tasks, etc. Thanks to import and export, it integrates seamlessly with your existing personal calendars without replacing them.

Yes, when creating an event, you can set a recurrence: daily, weekly, monthly, or yearly. This is handy for household routines (bin collection day, weekend cleaning), regular reminders (paying the rent), or important dates (birthdays). Each occurrence can be edited individually if needed.

Koabit allows you to sync the shared calendar directly with your phone's native calendar (Google Calendar on Android, Apple Calendar on iPhone). Go to Calendar → Settings → Sync to enable this feature.

Once enabled, Koabit calendar events will automatically appear in your regular calendar app. It's the easiest way to integrate the household schedule into your daily life without having to open Koabit every time.

Koabit offers 4 splitting modes to suit every situation:

• Equal shares: the amount is divided equally among the selected members. Perfect for shared groceries or dining out
• By percentage: each person pays a set percentage. Useful when incomes differ (e.g., 60/40)
• By fixed amount: you assign a specific amount to each member. Handy when everyone ordered something different
• By weighted shares: you assign a number of shares to each member (e.g., 2 shares for an adult, 1 share for a child) and Koabit calculates the proportional amount

You choose the mode when adding each expense, and you can exclude certain members if an expense doesn't apply to them.

Receipt scanning takes 3 steps:

1. Preparation: from the expense creation screen, tap the 📷 button at the top. You can either take a photo directly or import images from your gallery. If your receipt is long, take multiple photos.

2. Analysis: make sure the photos are in the right order (you can rearrange them by drag-and-drop or delete some). Then tap "Scan". The AI analyzes the receipt and automatically extracts each item with its price, promotions, the total, the store name, and the date.

3. Review: Koabit displays the list of all detected items and promotions. You can edit the name or price of each item, add or remove lines, and manage promotions (link them to a specific item or apply them to the entire receipt). If the app detects a discrepancy between the total read from the receipt and the total calculated from the items, a warning is displayed so you can correct it.

Once confirmed, the items become sub-expenses that you can split individually among household members: each item can be assigned to one or more members using the splitting mode of your choice.

To edit or delete an existing expense, tap on it to open its details:

• Edit: tap the edit icon (pencil). You'll see the creation form pre-filled with all the expense data (amount, date, category, split, sub-expenses). Make your changes and confirm.
• Delete: tap the delete icon (trash can). You'll be asked to confirm before permanently deleting the expense. The household balances will be automatically recalculated.

When you confirm an expense (manually or via scan), Koabit's AI automatically assigns a category based on the expense title and your list of available categories. Categories include: groceries, restaurants, transport, leisure, health, housing, subscriptions, and more.

Categorization happens at the time the expense is confirmed. If you're not happy with the assigned category, you can always change it afterwards by editing the expense. Categories are then used in statistics to visualize the breakdown of your spending.

Koabit automatically calculates the balances between each member of the household by taking into account all shared expenses. The app optimizes reimbursements to minimize the number of transactions needed: instead of everyone reimbursing each other, Koabit simplifies the flows.

For each reimbursement to be made, you can clearly see who owes how much to whom. Once the transfer or payment is done, tap "Mark as reimbursed" to update the balances. The full reimbursement history is available at any time.

Yes! If you travel or if your household is international, you can add expenses in any currency. Koabit automatically converts amounts using exchange rates updated once a day. Each member can set their preferred currency in their settings and will see all amounts automatically converted. This is especially handy on holidays abroad to keep a clear view of the group's expenses.

No, the household's main currency is set when the home is created and cannot be changed afterwards, as it serves as the reference for calculating all balances and reimbursements. If you need a different currency, you can create a new household with the desired currency. If you run into any issues, feel free to contact our team via the Contact button.

Yes, for regular expenses like rent, subscriptions (internet, streaming, electricity...) or any fixed charge, you can set up a recurring expense. Enter the amount, the members involved, the splitting mode, and the frequency (monthly, weekly, etc.). The expense will be automatically added at each due date, saving you from having to re-enter it every month.

Yes! Koabit lets you create, edit, and delete your own expense categories. For each category, you can choose an emoji, a name, and a color. Go to Expenses → Settings → Categories to manage them.

Categories are used to filter and sort your expenses, and to view the breakdown by category in the statistics. Koabit's AI also uses these categories for its automatic suggestions. Default categories are provided when the household is created, but you're free to customize them to suit your needs.

Koabit lets you create as many lists as you want, for any purpose:

• Shopping lists: add items throughout the week, check them off at the store
• To-do lists: for organizing a move, preparing a trip, planning an event
• Custom lists: gift ideas, movies to watch, recipes to try...

Each list can have its own name and icon. You can share them with the entire household or only with certain members.

Yes, all shared lists are instantly synced between all members involved. When someone adds an item, checks it off, or deletes it, everyone sees it immediately on their screen. This is especially handy for shopping: while one person is at the store, another can add a forgotten item from home and it will appear in real time.

Each list can contain as many items as needed. You can rearrange items by drag-and-drop to sort them in whatever order suits you (for example, by store aisle). Checked-off items are automatically moved to the bottom of the list to keep a clear view of what's left to do.

Every day, each household member can log their mood by choosing an emoji that represents how they're feeling, and add an optional personal note for context. Your mood history is saved and displayed as a calendar, making it easy to spot long-term trends: stressful periods, happy moments, the impact of events on the household's well-being. It's a simple yet powerful tool to take care of yourself and stay attentive to those around you.

Your mood visibility is fully customizable. You can choose to:

• Share your mood with the entire household (the emoji appears on the dashboard)
• Keep it entirely private (no one can see it)

In all cases, personal notes always remain private: only you can read them. This setting can be changed at any time in your preferences.

The security of your data is our top priority. Here are the measures in place:

• All data is encrypted in transit (HTTPS/TLS) and at rest on our servers
• We never sell or share your data with third parties
• No ads, no ad tracking
• The app complies with the GDPR (General Data Protection Regulation)
• Servers are securely hosted

You can read our Privacy Policy, accessible from the site footer, for more details.

Only the members you have invited to your household have access to shared data (tasks, expenses, calendar, lists). No one outside can view or access your information. If you want to control who joins your household, you can enable manual approval of new members (see the question "How do I prevent automatic access to my household?").

You can delete your account at any time from Profile → Settings → Delete My Account. Deletion is permanent and irreversible: all your personal data, history, and preferences will be removed from our servers.

If you are the last member of a household, that household's data (tasks, expenses, calendar, lists) will also be deleted. If other members are still present, your past contributions will remain visible to the household but will no longer be linked to your account.
