Hi everyone, I 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.

I’m a psychologist, and I think most focus apps measure the wrong thing. They only measure time. But lately I started wondering: does spending 25 minutes in front of a task actually mean we were focused?

What I kept noticing both in myself and others was constant “micro-distraction”:

• checking notifications,
• switching apps for a few seconds,
• opening social media automatically.

Tiny dopamine breaks that slowly destroy attention. The scary part is that we barely notice how often it happens. So I started experimenting with a different idea: what if instead of measuring productivity time, we measured attention consistency? That led me to build a small Android app. During a focus session, if I leave the app even briefly, the session loses part of its “integrity score.” It is not as punishment. More as awareness training. What surprised me most while testing it: people consistently overestimate how focused they actually are.

I included a screenshot of what the session integrity looks like in practice.

What usually breaks your concentration first? Have you noticed your attention span getting worse over the last few years?
