A workout timer you can read from the floor

Round & Rest shows one phase at a time as a full-screen block of colour with ultra-bold white digits. You read it in peripheral vision, phone flat on the ground, mid-burpee — including outdoors in direct sunlight.

Five formats, nothing else

• Intervals Work then rest, repeated. The classic HIIT structure.
• EMOM Every Minute On the Minute — a fresh round starts on a fixed beat.
• AMRAP As Many Rounds As Possible in a fixed window, with a round counter.
• For Time Count up until you finish, with an optional time cap.
• Circuit Several blocks, each repeating its own list of exercises.

Tabata is not a sixth format — it is intervals of 20 seconds on and 10 seconds off, eight rounds. Open a Tabata timer already set up.

Built for CrossFit, HYROX and benchmark WODs

• Timer for CrossFit The four formats a box actually uses, and which one fits your WOD.
• Timer for HYROX Eight runs, eight stations, one roxzone — time a piece or simulate the race.
• WOD Timer Fran, Cindy, Helen, Chelsea, Murph — preset and ready to open.

Why it looks like this

Most workout timers are designed to be read at arm's length, on a desk. A timer in a gym is read from three metres away, upside down, while you are out of breath. That single constraint decides the whole design: one flat saturated colour per phase, white digits as large as the screen allows, and no thin text, no gradients, no low-contrast greys.

There are exactly three sound cues — a countdown tick before the start, a go signal at each round, and an end signal. Not one more. A timer that beeps constantly stops being information and becomes noise.

Free, offline, no account

• No sign-up. Open it and use it. Nothing to create.
• No ads, no tracking, no data resale.
• Works offline. Install it on your phone and it runs in a basement gym with no signal.
• Nothing leaves your device. Your sessions and history live in your browser.

Describe your session out loud

Round & Rest also plugs into a conversational assistant. Say "three blocks of two one-minute exercises, four rounds, ninety seconds rest" and the timer appears in the conversation, already configured. Connect it to Claude or ChatGPT, or read what changes for coaches and athletes.

The timer also plugs into other tools — an assistant, a preset link, an ambient display: see the integrations, or mirror the session on a BUSY Bar.

Share a session

Every session fits in a link, and the app turns that link into a QR code. Whoever opens it gets the timer already set up — no account, no install. Useful for a coach handing the same session to a whole room.
