Nibbora is an Android study timer for students. You pick a countdown (15, 25, 45 or 60 minutes, or your own length) or a stopwatch, choose a subject and study. Every focused minute earns one sunflower seed, plus 5 bonus seeds when you finish a session of 25 minutes or longer. Seeds buy snacks that level up your hamster, hats it can wear and rooms it can live in; they cannot be bought with money. While the timer is running the app shows no full-screen ads. Sessions are stored on your phone and shown as day, week and month charts colored by subject, with a monthly report. If you study past midnight, a day-start setting (00:00 to 06:00) keeps late-night study on the right day.
1 minute = 1 seed
A fair reward: every focused minute earns a seed, and finishing a 25-minute session adds a 5-seed bonus.
No pop-up ads mid-timer
Nothing full-screen appears while you focus. A small banner stays at the bottom, out of your way.
A hamster that never gets sad
Pause or stop any time. Your hamster just naps, and you never lose seeds you earned.
Snacks, hats and rooms
Feed snacks to level up, try on a grad cap or a crown, and move from a cozy room to a library or the beach.
Study hours by subject
Day, week and month charts with subject colors, plus a monthly report with total hours, best day and top subject.
Built for night owls
Set when your day starts, so studying at 1 a.m. still counts toward yesterday and your streak stays correct.
Delete sessions that didn't count
Long-press any session in your stats to remove it.

FAQ
- Does it show ads while I'm studying?
- No full-screen ads appear while the timer is running. Nibbora is supported by a small banner and by occasional full-screen ads at natural breaks, such as when you open the app or after you close a session result. Never in the middle of a session.
- How many seeds do I get?
- One seed per focused minute. Finish a countdown of 25 minutes or more and you get 5 bonus seeds. Sessions shorter than 5 minutes are not saved.
- What happens if I pause or leave the app?
- The timer keeps counting from its start time, even if you switch apps. Pausing stops the clock; your hamster just naps and you keep every seed.
- I study after midnight — why does it count as the next day?
- Most timers split the day at 00:00. In Nibbora you can set the day to start at any hour from 00:00 to 06:00 in Settings, so late-night study counts toward the day you started.
- Can I buy seeds?
- No. Seeds, snacks and items are earned only by studying. There are no in-app purchases.
- Will it tell me when the timer ends?
- Yes, with a notification. Choose sound, vibrate or silent in Settings. It does not use exact alarms, so on some phones it can arrive a little late; if the app is open you see the result right away.
- Can I use it as a pomodoro timer?
- Yes. Start a 25-minute focus, then take the 5-minute break offered on the result screen.
- Do I need an account?
- No. There is no sign-up and your study history stays on your phone.
