Over time I built a small set of Android apps, mostly single-purpose utilities and one developer-focused companion tool.
Utility apps (no accounts, no subscriptions): - Offline PDF & EPUB reader/editor - QR & barcode scanner and generator - Phone hardware and battery diagnostics
Developer tool: - VSCoder Copilot – a mobile companion for VS Code / GitHub Copilot workflows
For the utility apps, the focus was: - minimal permissions - no background services - all on-device processing
VSCoder is different by nature and supports optional paid features.
I’d appreciate feedback, especially on UX decisions, permission discipline, and whether there’s still room for focused utility software on Android.

Of course, then monetization would only be from donations, but I think this decision attracted a larger audience, because the Play Market already has many similar programs and people search for them most often there and look at them number of downloads, so it will be more difficult to gain an audience there.
