One backend for web and Android: lessons from Lettzio
Lettzio runs as a Next.js site and a Flutter app on top of the same Supabase database. Sharing one backend saved us a lot of work, as long as security lived in the database.

Tracking per app data usage on Android without a VPN
Many data monitor apps run a local VPN to see your traffic. Data Usage Monitor does not. It reads the statistics Android already keeps, through NetworkStatsManager.

Building an offline first finance app with Flutter, Drift and Riverpod
Spendly keeps every transaction on the phone, with no account and no server. This is the stack behind it and why we chose a local database over the cloud.
