About this app

■ Time things together with your oshi

Oshi Timer is a cute timer & stopwatch you can use with your favorite image as the background.
Studying, Pomodoro, cooking, a countdown to a stream — make everyday timekeeping fun, together with your oshi.
All data is saved only on your device and is never sent anywhere (privacy-first).

■ Main features

[1] Your oshi as the background
Set any image from your device as the background, and adjust the zoom and position to frame your oshi just right.

[2] Multiple timers
Create and manage as many named timers as you like. Rename, edit the time, duplicate, or delete freely — one for studying, one for breaks, and so on.

[3] Stopwatch & lap times
Measure elapsed time and record laps. The fastest lap is shown in green, the slowest in red.

[4] An alarm that rings until you stop it
When a timer finishes, the alarm keeps ringing until you press "stop," so you never miss it.

[5] Choose your alarm sound
Pick from six sounds — Beep, Sparkle bell, Marimba, Retro (8-bit), Gentle, and Strong alarm. You can preview each one.

[6] Choose a theme color
Customize the app's accent color from pink, purple, blue, mint, orange, red, and soft pastel tones.
