Hardware specs to consider

In order to reach a good rating it‘s important to consider the screen size and resolution when designing the app UI:

PhonePixelsPoints1
PinePhone (Pro)720 × 1440360 × 720
Librem 5720 × 1440360 × 720
Moto G4 Play720 × 1280360 × 640
OnePlus 61080 × 2280360 × 760
Xiaomi Poco F11080 × 2246360 × 752

When landscape use and the mobile shell's own UI are also considered, this leads to a recommended dimension of 360×294px in GNOME's HIG for a fully mobile compliant app.2

Finding a project

If you have time on your hands, but don't have an idea (and looking through the app list has not helped you with coming up with what is not there nor inspired you to help out a listed project), you could do the following:

  • Pick up an existing project that's

    and go ahead and revive it!

  • Make adjustments to an app that mostly works, but does not really fit the screen and thus has a mobile compatibility rating of

If you rather want to start your own project, maybe the Wishlist on the Mobian Wiki can be a source of inspiration. If that's not it, maybe go through related subreddits, or the PINE64 or Purism forums to find out what people are longing for.

App Testing

If you don't have a device, get in touch by commenting on the issue linked below:

Points at default scaling of 2x on low-end devices, and 3x on Snapdragon 845 devices. Fortunately, all phones with good mobile Linux support default to a width of 360 points. 2: That said, few of our 5/5 rated apps actually fulfill the landscape criterion.
