Hear your timer. See your time add up. Chatty Timer brings voice cues, focus and workout timers, a talking stopwatch, and activity history together. Use it for study sessions, desk work, or training, then look back at the time you put in. FOCUS AND BREAKS Set your focus time, break time, and number of sets. Alternate between focused work and rest for Pomodoro study sessions or everyday tasks. Spoken start and end cues help you follow the routine without constantly checking the screen. WORKOUT INTERVALS Set work and rest periods and repeat them across multiple sets. Hear phase changes, remaining sets, and the final 3, 2, 1 countdown. Use timed intervals for HIIT or Tabata, or finish each strength-training set manually before starting your rest. SEE YOUR TIME ADD UP Save your activities and review daily, weekly, and monthly totals. Use labels to organize study, work, and workouts, and see your activity in daily charts. Set weekly or monthly time goals and check your progress. A TALKING STOPWATCH Hear elapsed time at the interval you choose. Record laps and splits, then pause and save the session to your activity history. SAVE YOUR ROUTINES Keep your favorite focus and interval settings as presets, ready for your next session. A standard timer and alarm are also included. Stopwatch elapsed time announcements continue while timing, even with the screen locked or another app open. Force-quitting the app stops announcements. Timer history follows each preset's save setting; stopwatch sessions are saved manually. BACKUP AND RESTORE Back up your alarm and timer settings and imported audio to iCloud.
