Tap a subject. The clock starts.
Hourlit is a simple study timer that tracks your study time by subject. Your subjects sit on the home screen with a play button each, today's total is shown in big numbers, and a goal ring fills as you study. No account, no study groups, no server: it works offline, so the timer always starts and your hours never reset to zero.
Get it on Google Play
One tap to start
Each subject has its own play button on the home screen. Tap it and the timer is running. No menus to dig through.
Today's total and a goal ring
See today's study time in big numbers. Set a daily goal and watch the ring fill as you study.
Full-screen focus timer
Subject, elapsed time and today's total on one calm screen. Take a break and resume; breaks are not counted as study time.
A timer that doesn't reset
Leave the app and it keeps running. Time is saved by start time, not by the screen, and a lock-screen notification shows the running timer with a Stop button.
Stats by day, week and month
Totals, daily average, time by subject with bars and percentages, and a month heatmap that gets darker the more you study.
Fix forgotten sessions
Forgot to start the timer, or left it running? Add or edit any session by hand so your log stays honest.
Built for exam season
A D-day countdown for your next exam, a study streak, and a "new day starts at" setting so 2 AM study counts for the day before.
Widget, share card, no login
Start a subject from the home screen widget and share a clean card of today's hours. Your data stays on your phone.
FAQ
- Does Hourlit work offline?
- Yes. There is no server, so there is no "can't connect to the server" error. The timer starts and stops on your phone, with or without internet.
- Does the timer stop if I leave the app or my screen turns off?
- No. The timer keeps running in the background and shows on your lock screen and notification shade with a Stop button. Time is calculated from the start time, so it never jumps back to zero. You can also keep the screen on while the timer is open.
- I forgot to stop the timer. Can I fix the session?
- Yes. Open the session and correct the time, or add a session by hand if you forgot to start the timer at all.
- Do breaks count as study time?
- No. Tap break in the focus timer and the clock pauses. Only the time you actually study is added to your totals.
- I study past midnight. Which day does it count for?
- You choose. Set when your day starts, for example 4 AM, and anything you study before then counts for the day before.
- Are there study groups, chat or rankings?
- No. Hourlit is a private study log just for you. There are no groups, no chat and no leaderboard to pull you away from studying.
- Is there a subscription? Are there ads?
- There is no subscription and no login. Hourlit is supported by ads, and there are no ads while the focus timer is running.
- Is my study data private?
- Your subjects and sessions are stored only on your phone. There is no account, and nothing is uploaded to a server.
