Gloves on? Ask Siri.
“Siri, start Heavy bag in Ringside.”
Saved timers start by name. Or say “Start intervals in Ringside” and Siri asks for rounds, round length and rest.
Ringside: Round Timer
Boxing, skipping & HIIT timer · iPhone
Ringside
No ads. No account. Just rounds.
The round timer you can read from across the gym. Set your rounds, work and rest, press start, and the whole screen becomes the timer.

The running screen
The whole screen is the timer.
Red for work, blue for rest. The colour drains down the screen as each round runs out, so one glance from the bag, the rope or the treadmill tells you where you are. Huge numbers, readable from metres away, and the screen stays on for the whole session.

Short on time?
Drag the colour.
Pull the colour down to speed a round up. Push it to the top to start the round again. Drag along the round strip to jump anywhere in the workout. Pause, skip or restart with big, glove-friendly buttons.
Try it: drag the colour on the timer up and down.

Sounds for every timer
Every alert, your way.
Each timer has its own sounds, as beats or voice. Count yourself in before round one, hear “4 minutes left”, and count down the last 3, 5 or 10 seconds of every round and rest. Sounds play over your music, keep going with the phone locked, and still play with the silent switch on.
Tap a sound to hear the last three seconds. These are the real sounds from the app.
A real boxing bell
Phone locked? Still counting.
Bells and countdowns keep playing on time with the phone locked or another app open. The countdown shows on your Lock Screen and in the Dynamic Island.
Your rounds
Saved. Ready to go.
Heavy bag, skipping, shadow boxing, treadmill: set each one up once, from a quick 30 seconds to two-hour sessions, and start it with one tap. Edit a timer mid-workout and you keep your place when you save.
Light and dark mode, big text friendly and VoiceOver ready.

The sounds stop when my phone locks
They shouldn't: Ringside keeps playing bells and countdowns with the phone locked while a workout is running. Check the speaker button on the running screen isn't crossed out, and that your iPhone's volume is up. The silent switch doesn't mute Ringside. Sounds pause while the workout is paused.
The screen turns off during a workout
Tap the “Screen stays on” button at the top of the running screen. If it says “Screen can sleep”, the screen is allowed to turn off.
I can't see the countdown on my Lock Screen
Go to Settings › Ringside and make sure Live Activities is on. It only shows while a workout is running.
Siri opens the Clock app instead
Say the app's name, Ringside, at the end: “Siri, start Heavy bag in Ringside”. Use the timer's name exactly as it appears in the list. After installing, Siri can take a few minutes to learn the phrases. You'll also find them in the Shortcuts app under Ringside.
How do I change the beeps, bell or voice?
Tap a timer's name to edit it, then scroll to the sound sections: Before start, Minutes left, Final countdown and Round bell. Each has Off, Beats or Voice, plus a choice of eight sounds. Use “Hear it” to try them.
How do I speed up or restart a round?
On the running screen, drag the colour down to take time off the current round or rest, or push it to the top to start that part again. You can also drag along the strip at the bottom to jump anywhere in the workout.
How do I delete a timer?
Swipe left on it in the list, or open it and tap Delete Timer at the bottom.
Do you collect my data?
No. There's no account, no ads and no tracking, and nothing leaves your phone. See the Ringside privacy policy.
