About Customodoro

Customodoro is a handcrafted productivity timer built to help you focus better, manage your time, and maintain balance.

Why I made this? I built this for someone special — my girlfriend — because she told me the traditional Pomodoro style wasn't working well for her study sessions. So, I designed Reverse Pomodoro just for her — something more gentle and flexible, the way she needed it.

This app is for anyone who wants to focus with intention, rest with clarity, and make every session feel like progress.

Handcrafted by YabuTech — born from feedback, built to empower.
