Flotti
An otter budget app that floats on the money you have left today
When you spend, just type the amount. Flotti the otter floats on the water by as much as you can still spend today; go over and it dives for a moment, then surfaces again tomorrow. You can log spending without opening the app, through the home screen widget or by sharing an order screenshot. Your records are stored only on your device. Logging is free, and there is a subscription (Pro).
Start small, ship all the way.
Two people, from idea to operations.
We split planning, design, development, store review, and post-launch operations and ads between us.
We pick the tools each app needs.
Our apps are built with Flutter, React and Capacitor, Godot, and Swift. We don’t fix the stack in advance.
Every app states what it collects.
Every app has a privacy policy and a support page that list the data it collects, item by item.
