BlockGain's focus timer, 24:58 left in the first round, with Instagram, YouTube, TikTok, Snapchat and Netflix blocked

01 · Focus

Two taps, and you're studying

Pick a timer or Pomodoro rounds, see exactly how your session splits into focus and breaks, and start. Your blocked apps stay closed until the timer ends.

  • Timer or Pomodoro, breaks built in
  • Your distracting apps, blocked for the session
  • Strict mode: no stop button, no way to unblock
  • YouTube study mode: only your study channels
The session setup: Pomodoro rounds, the session bar, blocked apps, and Strict mode and YouTube study mode

02 · Plan

Know when you study

Set your study times once: mornings on weekdays, longer sessions at the weekend, whatever fits. BlockGain reminds you as each one starts, and one tap opens the timer set to the right length.

  • Weekday and weekend schedules
  • A reminder when each one starts
  • Open a blocked app at study time and "Time to focus" asks first

03 · Get up

An alarm that sends you to your desk

Turn on alarm reminders and a real alarm rings when your study time starts, even on silent. Pick a picture and a sound you like, then tap Start focus and your timer is ready.

04 · Look back

See your week of focus

How long you really focused, how long you spent in the timer, and every day of the week against your goal. Plus your screen time, so you can see where the rest went.

Focus time for the last 7 days: hours focused, time in the timer, sessions done and a bar for each day

Free, for every student

No subscription, no paywall, no account. The timer, blocking and schedules are always free. Strict mode, YouTube study mode and ending a session early are free with a short ad you choose to watch.

Questions

Does it work on iPhone?

Yes. On iPhone, BlockGain uses Apple's Screen Time to block apps and websites while you focus. Apple doesn't let apps see inside YouTube or Instagram, so on iPhone you block whole apps, not just Shorts or Reels.

Can I stop a session early?

A normal session, yes: end it after a short ad. In Strict mode, no. It ends when the timer does, so turn it on when you really mean it.

Is it free?

Yes. There's no subscription. Strict mode, YouTube study mode and ending a session early are free with a short ad. There are no ads anywhere else.

Why does it need Accessibility on Android?

It's how Android lets an app see which app is open, which blocking needs. BlockGain explains exactly what it reads before you turn it on, and nothing it reads is stored or sent anywhere.

How do I delete my data?

Everything is on your phone. Uninstall the app or clear its storage and it's gone. There's nothing on our side to delete.
