Two-phase timer
Built around one repeating rhythm: Ten, then Three.
Minimal Timer App
Ten Three
A simple two-phase timer for focus and reset.
Ten Three is a lightweight timer built around a repeating flow of Ten and Three. Start a phase, pause when needed, and switch directly between the two without extra setup.
What Ten Three is
Ten Three keeps one repeatable rhythm in view. It is meant to feel immediate, clear, and easy to return to throughout the day.
Instead of adding setup screens, presets, or extra tracking, it stays focused on a single job: helping you move between Ten and Three with as little friction as possible.
Direct phase switching
Tap Ten or Three at any time to move directly into that phase.
Simple controls
Start, pause, resume, and reset without digging through menus.
Minimal by design
The interface stays out of the way so the rhythm stays clear.
How it works
The flow is intentionally small. Start, switch, pause, and repeat.
01
Start Ten or Three
Begin with whichever phase you need right now.
02
Let the phase run
Keep the timer moving, or pause if you need to stop.
03
Switch directly when needed
Jump between Ten and Three without extra setup screens.
04
Repeat as long as you want
Use the same calm loop for work, rest, focus, or reset.
Why it is intentionally minimal
Ten Three is not meant to be a larger productivity system. It keeps one simple rhythm visible so you can begin quickly and stay in it.
The goal is speed, calm, and clarity. No clutter, no extra setup, and no need to manage more than the timer itself.
