Feature Status

The app does not try to replicate every single feature that the Webinterface has. Instead, it tries to be a good companion to access the most used functions on-the-go. More in-depth operations such as creating or modifying rules are not planned for this app.

If you are missing anything, feel free to open a feature request, or look at what other users are requesting.

Releases

The stable releases are published to the Google Play Store, and are also available for download from the GitHub releases page. There is no fixed release schedule.

You can also opt in to the (open) beta channel at Google Play here. The beta channel will feature the "pre-releases" from the GitHub releases page, and might not be as stable.

Technology

The app is built using Flutter, and tries to keep to the Material 3 design guidelines. Additionally, I try to keep the app as "lean" as possible, without any trackers or unneeded dependency on external packages.

Motivation

Having troubles with Bluecoins syncing across devices and not always storing attachments online, I was looking for a self-hosted alternative and discovered Firefly III. After a quick script to migrate from Bluecoins to Firefly III, the only thing left was to download an app to easily track expenses on-the-go… or so I thought.

Unfortunately, I discovered that the existing Android Apps for Firefly III had been either outdated or very buggy and hardly maintained. Always wanting to use Flutter for something, I started to make my own app, modeling it after the Bluecoins app I used so far and its interface that I really liked.
