About

Focus Timer

Features
Read full description

Focus Timer is a Pomodoro timer for studying and deep work: run focused sessions on your tasks and see how much time you really spent focused. All features require a subscription or a one-time purchase. Work in short, focused blocks with regular breaks. Pick a task, start the timer and let the Pomodoro cycle carry you — focus, short break, repeat, and a long break after every round. Your study time, sessions and daily goal are tracked for you, so you always know where your day went. FEATURES: • Pomodoro timer – focus sessions with short and long breaks and round dots that show where you are in the cycle. • Custom timer lengths – set your own focus, short break and long break lengths and the number of rounds. • Auto-start – start the next session or the next cycle automatically, or keep full control. • Task list with a timer – start a focus session right from a task and see the focus time of every task. • Study tracker – focus charts by day, week and month for focus time, total time and sessions. • Session timeline – every session of the day on one timeline, breaks included. • Daily goal – set a daily focus goal and watch your progress towards it. • Streak – keep your focus streak alive day after day. • Heatmap – see your focused days at a glance. • Session-end alerts – a notification when a focus session or a break ends. • Keep screen awake – leave the timer visible while you work. • Simple interface – one tap to start, nothing in the way. • Private by design – your sessions and tasks stay on your device. HOW IT WORKS: 1. Choose a task and start a 25-minute focus session. 2. The timer rings when the session ends. 3. Take a 5-minute short break. 4. After four sessions, take a longer break. 5. Turn on auto-start and the next session begins on its own. Great for students preparing for an exam, for homework and study sessions, and for anyone who wants to beat procrastination at work.
