# Rounds

> Rounds is a gym interval timer for iPhone. The round, seconds left and next movement live on your Lock Screen and Dynamic Island. The phone stays locked.

This file describes Rounds, a gym interval timer for iPhone made by UpSys Consulting. The App Store name is "Rounds Gym Interval Timer".

## The app

- Timers: Tabata, EMOM and any work and rest structure you can write in seconds, with sets and a break between them.
- Lock Screen: a Live Activity shows the round, the seconds left and the movement you are on, in the Dynamic Island too. Pause and skip are buttons there, so the phone stays locked.
- Movements: name what you do in each round, with reps and weight, and the Lock Screen says which one is next.
- Sound: a rising tone into work, a softer one into rest and 3 ticks before every change. Your music dips under the cues and keeps playing.
- No drift: the workout is laid out as a timeline when you press start, and the time left is read from the clock, so a suspended app wakes on the right round.
- Privacy: no account needed, works offline, no ads, no analytics and no tracking.

## Availability

- iPhone, iOS 27 or later.
