Rest timer
Finish the set.
Tap once. Rest.
Prop the phone where you can see it. One tap when you put the weight down, three beeps when it is time to pick it up again.
How to use it
- Choose the rest length your plan calls for.
- Do your set. When you put the weight down, tap the dial.
- Rest. You will hear a tick at 3, 2 and 1, then a clear tone when rest is over. With sound off, the dial flashes instead.
- Lift again, then tap again. The timer keeps count of your sets.
Small things that make it nicer
- The screen stays awake while the timer is running, on browsers that allow it, so the phone does not lock mid-rest.
- Need longer? “+15 s” adds time to the rest you are in without changing your setting.
- Ready early? “Skip rest” ends it and waits for your next set.
How long should you rest?
That depends on the exercise, the load and how you feel that day, so this page does not pick a number for you. Use the rest length in your programme, or what your trainer or clinician has suggested. If you feel dizzy, unwell or in pain, stop the session.
This page is a timer, not exercise or medical advice.

Questions
How does a rest timer between sets work?
You tap once when you finish a set. The timer counts down your chosen rest, warns you in the last three seconds and signals when it is time for the next set.
Will the timer keep my phone screen on?
It asks the browser to keep the screen awake while a rest is running. Most current browsers allow this; if yours does not, raise your auto-lock time for the session.
Does it work with the sound off?
Yes. The dial changes colour and flashes when rest is over, and phones that support vibration will buzz.
Does it save my workout?
No. Set counts and times live on this page only and clear when you close it.
