Hi everyone, I’m a psychologist and recently built an Android app called Focus Nest.

Most focus apps only track session length, but I became more interested in something else: how often we interrupt our own attention while supposedly “focusing.”

So I designed an Integrity System:

✔ Lock screen → session continues

✔ Phone calls → session protected

✖ Intentionally leaving the app → you get a system notification, the session loses integrity and is paused until you resume it.

The idea isn’t punishment. It’s awareness of attention-switching habits.

The app includes:

5/15/25/45/60 minute deep work sessions

ambient focus sounds

productivity analytics

interruption tracking

minimalist UI

• No account required • Instant start • Clean Pomodoro & deep work timer • Refined haptic feedback • Distraction-free interface • No unnecessary features

Every detail serves one purpose: deeper focus.

Would genuinely love feedback from the Android community.

Focus Nest - a deep work timer that measures attention interruptions, not just time
