About Simple Interval Timer
Simple Interval Timer (SIT) can be used for any kind of interval training, such as running, cycling, HIIT sessions (including Tabata method), stretching, etc.
SIT is exactly what you would expect. An interval timer, which is easy to set up and use. It features a nice plain design, with no unnecessary controls.
Adjust Number of Sets, Action and Break duration to your needs and you are ready to go!
On the iOS an extra switch control allows you to prevent the screen from dimming.
SIT remembers the last 5 configurations you have used. Swipe left across the Settings screen to switch to another configuration.
SIT can run in the background, while you are playing music, watching videos or doing anything else on your iOS device.
SIT Watch features the same simplicity as the iOS app while offering the same functionality, plus it will measure your heartbeat during the workout sessions. The recordings will be available in the Apple's Health app.
SIT Watch runs independently of the phone, so no need to have your phone around during your workouts (although you will need your phone during the very first time you launch SIT watch).
SIT lets you avoid any tedious set up and focus on your training!

Apple Watch companion app is just as simple as the SIT iOS app. Adjust the number of Sets, Action and Break duration to your needs and you are ready to go! The app will notify you with a single haptic at the beginning of each set, and with a double one at the beginning of each break.
You will only need your phone during the first time you run SIT watch, after that SIT Watch will run independently, so no need to have your phone around during your workout.
The SIT Watch remembers the last 5 configurations you have used. Swipe left across the Settings screen to switch to another configuration.
