# Questions about Flatsby > Answers about Flatsby: price, Android and iPhone, splitting rent by percentage, moving from Splitwise, privacy and the AI assistant. Updated: 2026-10-09 Short answers to what people ask before they move their household into Flatsby. ## Questions ### Is Flatsby free? Yes. Shopping lists, expenses, settlements and groups are free, with no member limit. The AI assistant and automatic categories use credits: 5,000 a month for free, 40,000 on Starter ($4.99 a month) and 100,000 on Pro ($9.99 a month on the web). On iPhone, Pro is $7.99 a month in the US App Store. ### Does Flatsby work on Android? Yes. Flatsby is in the Google Play Store, the App Store and on the web at flatsby.com. It is the same account and the same data on every device. ### Can I move my expenses over from Splitwise? Yes. Export your group from Splitwise as CSV, then upload it under Group settings, Import expenses. You pick the currency and match Splitwise names to your flatmates. Each expense keeps the exact amount every person owed, so percentage splits arrive as amounts. Rows in other currencies or with several payers are skipped, and the preview lists them first. ### How does Flatsby split an expense? Equally, by percentage, by shares (for example 2 parts to 1), or by exact amounts per person. Expenses can be in EUR, USD or GBP, and Flatsby keeps a running balance per person for each currency. ### Can I set up rent as a recurring expense? Not yet. Add rent as a new expense each month. Each expense keeps its own split, so a 60/40 rent split and a 50/50 grocery split can sit in the same balance. ### How many people can be in a household? There is no member limit. A group admin adds each flatmate by the email they signed in with. ### Is the web app the same as the phone apps? Almost. Lists, expenses, settlements and group settings work on the web, iPhone and Android. The AI assistant is web only for now. ### Do shopping lists update in real time? Not instantly. Everyone shares the same lists, and a flatmate's changes show up when you open the list again or come back to the app or tab. ### What does the AI assistant do? In the web app, you ask about your household in plain language. It reads your lists and expenses, answers with charts and tables, and can add items or expenses for you. ### Who can see my household's data? Inside Flatsby, only members of your group. The hosting, analytics and AI providers listed in the privacy policy process it to run the app. Two features send data through the Vercel AI Gateway. The AI assistant asks for consent first, uses OpenAI or Google models, and its data is not used to train them. Automatic categories send the names of shopping items and expenses to a classification model. You can export all of your data or delete your account from your settings. ### Is Flatsby open source? Yes. The code for the web app, the mobile apps and the server is on GitHub under the MIT license. There is no public API for other apps. ## More about Flatsby - [Home page](https://www.flatsby.com/index.md) - [A shared shopping list the whole flat can use](https://www.flatsby.com/features/shopping-lists.md): One shopping list for the whole flat on web, iPhone and Android, sorted by category, with who added each item.
