Timer
Read full descriptionHide full description
An interval timer for routines you build yourself: any number of steps, in any order, repeated as often as you like, with your own voice and your own pictures. Free. No advertising, no purchases, no subscription. A COUNTDOWN YOU CAN READ ACROSS THE ROOM One number, as large as the screen allows. The exercise plays in a band above it while you copy the movement, and a bar along the bottom shows every round, step and rest at once — so you always know how much is left. YOUR OWN VOICE Record a note for any step and hear it the moment that step arrives. Where you have not recorded one, the phone reads out the step's name as it begins, so you are never guessing what to do next. IT WORKS WITH THE SCREEN OFF The cues sound with the phone locked and in your pocket, and they sound through the silent switch. A timer that goes quiet when you need it is not a timer. TWO ROUTINES TO START WITH A back stretch and an active workout, filmed and ready to run. Change them, or build your own from nothing: your steps, your durations, your rests, and a video or a photograph behind each one. SIX COLOUR THEMES The original gold, plus Aquatic, Nature, Candy, Energy and Lagoon. Chosen in the settings, applied everywhere the app draws — the running screen included. Every one is measured for contrast, so the countdown reads the same in pink as it does in gold. NOTHING LEAVES THE PHONE No account, no sign-in, no analytics. The app holds no network permission at all, so it could not send anything anywhere even if it were asked to. Your recordings and your pictures stay in the app's own storage and are deleted with it. MADE TO BE USED MID-SET Large type, high contrast, full VoiceOver support with each phase announced as it changes, and haptics for when the ear misses a cue. Twenty-seven languages.

Verdict
The clearest difference is in-app purchases: Timer at none against Lets HIIT's 2. Timer also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
