Afraid of waking the person next to you? Never miss an alarm again. 'Nenne' is a nap timer that plays alarm sounds exclusively through your earphones. Because no sound comes through the speaker, you can sleep comfortably at the library, on the subway, or at your office desk without worrying about others. [At a Glance from Your Home Screen] - 3 Home Screen Widgets: Nap Timer, Wake-up Alarm, and Combined Nap + Wake-up Alarm. Check remaining nap time and scheduled wake-up alarms without opening the app. [Personalize to Your Style] - Light & Dark Mode Automatically switches with system settings, or manual selection in Settings. - More Alarm Sound Choices Expanded from 9 to 22 sound options. Browse by theme (melodies, chimes, nature, SFX) and preview before selecting. [Why Earphone Alarm is Different] - Plays ONLY through earphones Alarm audio never leaks to the speaker, so you won't wake people nearby. - Pauses when earphones are unplugged Unplugging your earphones while the alarm is ringing automatically pauses it. No need to hurry and pull out your phone—just remove the earphones to stop the sound. - Resumes when reconnected Plugging the earphones back in resumes the alarm. Designed so you won't miss an alarm if the cable accidentally gets pulled out. - Supports wired & Bluetooth earphones Works seamlessly with both 3.5mm wired earphones and Bluetooth devices. - Switch modes while timer is running If you find yourself alone, switch between Earphone and Speaker modes anytime during the timer. - Precision down to the second Set your target time down to seconds, not just minutes.
