About this app
HAT is an Android app that answers a question most people never think to ask: where did my day actually go?
It does this by watching your app usage — something Android already tracks in the background — and inverting it. Every minute you weren't on your phone becomes a labeled block of time called a gap. You can leave those gaps empty, or fill them in: Sleeping, Working, Reading, At the gym. Over time, you end up with a complete picture of how you spend both your screen time and your offline time.
There are no accounts. No servers. No cloud sync. HAT has no internet permission at all — it can't send your data anywhere even if it wanted to. Everything lives in a local SQLite database on your device. You own it completely.
