Tsumoru: Practice Timer
Track Study & Reading Hours
Free
See your reading, study and practice hours add up. Start from your iPhone or Apple Watch and look back on your week. No ads, no account. NFC tags are optional.
Track the time you spend reading, studying and practicing with Tsumoru. Start a timer, save your session, and see your hours add up. A fifteen-minute session counts too. Taking a day off never resets your total.
START, FINISH, SAVE
Choose a category and start the timer on your iPhone. Name your categories for what matters to you: language study, piano, reading or another skill. Create as many as you need. No NFC tag or Apple Watch required.
SEE YOUR WEEK AND YOUR PROGRESS
• See your time by weekday in a weekly chart
• Review each category's total and the last 12 months
• Set an hours goal and daily or weekly time budgets
• Estimate when you will reach your goal at your pace over the last 7 days
MORE WAYS TO START
Start and end sessions from your Apple Watch. Use the Action button, or hold your iPhone to an NFC tag on your book or desk. Tap the tag again to finish. NFC is optional and needs a tag, sold separately, plus a Shortcuts automation set up once.
PAUSED TIME DOESN'T COUNT
Optionally block selected apps during a session. To use one, choose to pause and unblock, then reopen that app. Paused time is excluded from your record. Return to Tsumoru to resume the same session.
YOUR TIME, AT A GLANCE
See today's time and your running session on the Lock Screen, and your total and category breakdown in Home Screen widgets. Tsumoru also supports Live Activities, the Dynamic Island, StandBy and Apple Watch complications.
KEEP PAGES AND NOTES
Photograph the page when you finish reading to capture its page number. Dictate a note to remember what you worked on. Enable these options for each category. Text recognition and speech recognition run on your device.
KEEP YOUR OWN PACE
No ads, no account, no streaks, no rankings and no notification reminders. Records come from the timer. You can shorten or delete a session, but you cannot add time manually or increase recorded time.
Records are stored on your iPhone and in your own iCloud. Export to CSV or JSON, or choose to save completed sessions to Calendar.
