Declare war on chaotic calculation of expenses
The perfect app for couples 🙂 We use the shared shopping list almost every day and then share the costs directly in the app. And the cleaning schedule is also very useful 😂

Android / CouplesGreat app for organising shared flats! You have a shared calendar for all flatmates, cleaning schedule, shopping list and easy accounting of who has paid what. We only organise these things in our shared flat using the app… Really practical!

Android / WG BewohnerIt’s so easy to see all the important things. No more stress when it comes to cleaning. The checkout function makes it easy to lay something out. Definitely 5/5*!

iOS / CoupleDid you know that you can try FlatUp!…
…without registration?
Creating an account for an app that you don’t even know yet is pretty annoying. That’s why we’ve gone to great lengths to provide you with an anonymous login. This way you can test FlatUp! without registering and find out if it’s what you’re looking for. All the functions of our household app are listed here. If you have any questions, just write to us.
FlatUp! the upgrade for your household!

How do I edit an article?
To edit an article, simply click on the word of the respective article. This will open the editing screen where you can change the name and, if necessary, the category of the item.
Can I view the ticked items?
Yes. When viewing your shared shopping list, you will see a tick symbol in the top right-hand corner. This is either slightly greyed out or fully visible. You can show and hide the ticked items here.
I want to categorise my items - is that possible?
There are two ways to do this. Either you edit the respective article by simply clicking on the word. Or you can click on the pencil icon in the top left-hand corner of your shared shopping list view in the app. Here you can now select the category to which you would like to add items. This option is best if you want to add several items to one category.
