Dimodoro | Screen Dimming, Timer, Pomodoro

Dimodoro is an Android app that combines a screen dimming feature with a timer and Pomodoro function. Each can be used independently.
You can save combinations as "Routines" and start them all together.

On November 10, 2026, we released the official version on Google Play. Currently available in Japan and the United States. Thank you to everyone who participated in the closed testing!

Examples of how you can use it

🌙 Dimming + Timer

Before bed, use "screen dimming + 7-hour timer."
Set a 7-hour target until the next morning, and combine the action of reducing screen brightness before sleep with starting the timer in one step. You can adjust the time to suit your needs.

📚 Dimming + Pomodoro

For work or study, use "screen dimming + 25 minutes focus → 5 minutes break."
When you want to separate work and break time, you can switch between focus and breaks while reducing screen brightness.

🏃 Timer + Timer + Timer

For daily exercise, use "10 minutes warm-up → 30 minutes running → 5 minutes cool-down."
Combine timers of different durations to create your own flow.
