What’s new
Version 1.4 · Updated October 5, 2026
【New】 Pro users can now see their active timer in real time on the Lock Screen. ・Stopwatch and countdown: Shows the subject name and elapsed／remaining time ・Pomodoro: Shows the total session time ・When you pause the timer in the app, the Lock Screen display pauses as well ※Due to an iOS limitation, the Lock Screen cannot display transitions between work and break periods in real time for Pomodoro, so it shows the total session time. Work/break transitions and the end of the session are announced by notifications. To see detailed progress, please open the app. 【Change】 Study records are now assigned to the start date instead of the end date. For example, if you start studying at 11:00 PM on Oct 3 and finish at 1:00 AM on Oct 4, the record will be assigned to Oct 3. ・Records that span midnight will not appear in the “Today” list on the Record tab. You can find them in the History tab under their start date. ・The “Date” field on the record screen is now labeled “Start Date & Time.” ・Existing timer records were saved with a date and time close to when the timer ended. If you want to correct the date of a record that spans midnight, open the record and edit its start date and time.
