Unlike timers that keep counting just because they're left on, Tomatoma's camera AI skips the time you're away from your desk and counts only your pure focus time. Study, work, or reading — the time you focus never goes to waste. Every 10 minutes of focus earns you 10 tomatoes. Raise animals, compete in leagues, and survive in the Survival Game. The more tomatoes you collect, the more there is to enjoy! AI study timer that counts only pure focus time The camera AI checks whether you're at your desk. If you step away for more than 30 seconds, the timer pauses and resumes when you're back. Only the time you actually stayed and focused is recorded. 10 minutes of focus = 10 tomatoes Tomatoes stack up every time you complete a focus session. Use them to enjoy everything below.
