Lighthouse Prep · Focus timer

A focus timer that tracks every minute of real study.

Run timed study sessions that stop themselves, silence your phone automatically on Android, see how much of each planned session you really studied, and watch your real study hours add up — for SSC, UPSC, banking, TNPSC, RRB and GATE.

One timer for focus and progress

Most timers are just a clock with a beep. Lighthouse Prep's focus timer runs your session and records every focused minute against a real topic in your study plan — so the time you put in turns into visible progress, not just a daily number.

What the focus timer does

  • Sessions that stop themselves — each session runs for its scheduled length, keeps going when you lock your phone, and stops when the time is up, so a two-hour block is really two hours.
  • Tied to your plan — every session counts toward a topic you're actually studying for SSC, UPSC, banking, TNPSC, RRB or GATE.
  • Real study-time tracking — your focused hours add up by day, week and month, so you always know how much you really studied.
  • Works offline — the timer keeps running with no connection and syncs when you're back online.

Focus Shield — your phone goes quiet automatically

On the Android app, Focus Shield silences your phone the moment a session starts and brings it back the second it ends — without you touching a thing. Notifications stop sounding, calls go quiet through Do Not Disturb, and you can see a small count of how many distractions were blocked.

It switches on automatically whenever a study session is running or you've opened the current-affairs reading sheet — both count as real study time. You can also turn off the auto-on behaviour and control it yourself. Focus Shield is Android-only: on desktop and iPhone the rest of the app works exactly the same, just without the phone-silencing.

See where your time actually goes

The wastage report puts each session's planned length next to the minutes you actually studied. Over a few weeks it shows your real patterns — which sessions keep falling short, and by how much.

Your study history, ready to download

Every session you run is recorded with its date, its planned length and the minutes you actually studied. Studied without the timer? Correct the session in the wastage report. When you want it all in one place, Export PDF Report in the menu downloads the whole history.

Frequently asked questions

Is this a Pomodoro timer?
Not a separate Pomodoro mode. Each session runs for the length set in your plan — 25 minutes for a Pomodoro-style block, or 50 or 90 for deeper work — and stops itself when the time is up, with the breaks between sessions left to you. Every session counts toward a topic in your study plan.
Can it silence my phone while I study?
On the Android app, Focus Shield turns on automatically the moment a session starts — notifications go quiet and Do Not Disturb engages — then switches back off when the session ends. It isn't available on desktop browsers or on iPhone/iPad, where Apple doesn't let apps control Do Not Disturb.
Does it track how much I actually studied?
Yes. Every focused session is logged against the topic you were studying, so you can see your real study hours by day, week and month — not just a vague sense of effort.
Can I download my study history?
Yes. Export PDF Report in the menu downloads a summary of your sessions and how much of each you actually studied. If you studied without the timer, you can correct a session's studied time in the wastage report first.
How is wastage tracking different from the timer?
The timer measures the time you actually studied. The wastage report puts that next to the time each session was planned for, so over a few weeks you can see which sessions keep falling short, and by how much.
Is it free?
Yes — the focus timer and study tracking are free to use.
