Features & Capabilities

Simple Interval Timer (SIT) is a minimal, easy-to-use timer designed for all kinds of interval training. Set the number of sets, action duration, and break duration to match your workout, whether it's HIIT, Tabata, running, cycling, or stretching. The clean interface avoids distractions, helping you focus on your training. It also remembers your last five configurations for quick switching.

On iOS devices and with SIT Watch, you can run in the background, prevent the screen from dimming, and track heart rate during workouts. Workout data can sync to Apple Health, and SIT Watch can operate independently after the initial setup, so you can train away from your phone.

User Reviews

The Simple Interval Timer is praised for its simplicity, reliability, and flexibility across workouts and devices. Reviewers highlight its easy setup, strong interval customization, and useful cross-device/background operation. Common drawbacks mention routine management issues (default routines, duplicates, deletion) and occasional audio glitches, plus concerns about ads or paid upgrades in the free version. Overall, it’s a lightweight, effective timer for fitness and tasks, with room to improve routine handling and sound reliability.
Pros
  • Very easy to use with a simple, uncluttered interface.
  • Highly customizable intervals (reps, durations, breaks) for HIIT, run/walk, and more.
  • Reliable audio cues and stays on track without interrupting workouts.
  • Works across devices and in the background (Apple Watch, iPad) and remains visible when needed.
  • Free to use without mandatory subscriptions.
Cons
  • Difficult to manage routines/defaults; editing can create duplicates and there’s no easy delete option.
  • Audio can be unreliable—sounds occasionally don’t play consistently.
  • Ads in the free version and paid upgrade concerns; some users feel paying is not worth it.

I love this timer because it’s straightforward and simple. I love how it will tell you when to walk and run. Using this for my training block this summer. However, it’s frustrating and annoying when if you need to stop in the middle of the run it doesn’t pause automatically. Actually, it doesn’t pause at all manually either. I tried pausing it yesterday when I needed to use the bathroom. My 2 other run apps will pause automatically when it senses I have to stop. If the developers of this app can figure out a way to make it pause automatically, I will give it a 5 star rating and purchase the upgrade.

I don’t need my interval timer to win a design award. I just need it to work — and this one is great! No bloated features, no flashy UI trying to impress me, just a clean, functional tool that gets out of the way and lets me focus on my workout. Honestly, more apps could learn from this approach. Simple is hard to do well, and the developer nailed it.
