Mobile punishes ambition. The apps that survive do one thing on the home screen and hide everything else behind intent.
Decide the home screen first
Whatever occupies the first screen is what your app is. If it is a menu, your app is a menu. Put the primary action there and let navigation be secondary.
- One primary action, reachable with a thumb.
- State that survives a cold start — nothing worse than a spinner on launch.
- Optimistic writes with honest failure, so it feels instant and never lies.
- Notifications that earn their place or none at all.

Build a habit tracker mobile app.
Today screen: today's habits as large tap targets, one satisfying
completion animation, streak count per habit.
History: month grid heatmap, tap a day to see what was done.
Habit detail: rename, schedule (days of week), archive, delete.
Data: habits and check-ins per user with row-level security, streaks
computed server-side so two devices agree.
Offline: cache today's list, queue check-ins, reconcile on reconnect.
Design: dark-first, high contrast, thumb-reachable, no decorative
illustration. Motion is physical — things settle, they don't bounce.Paste it as your first message, or send it straight through.Build with Luminax
