This timer meets the needs of amateurs as well as professionals. It was designed to be flexible and highly customisable so it can be used for all kinds of trainings. There is one important difference between this app and other apps on the App Store. No need to change timer configuration when switching exercises all the time. Create and configure timers once and use them multiple times. For more demanding users timers can be composed into entire workouts. All timers and workouts can be categorized into groups.

For each timer can be enabled location tracking. With enabled location tracking you can seethe route and location based statistics like distance, speed, pace and altitude.

Another great feature is support for heart rate training using a Bluetooth LE heart rate monitor. User can create multiple profiles and switch between them. Heart rate training profile contains all settings for your training like heart rate zones and notification options. During exercising user can be notified about current heart rate and zone. One heart rate zone can be selected as target zone. Voice coaching can notify the user to adjust tempo to stay in current zone.

The user interface is designed to be clear and readable from a distance. For notification can be used vibrations, sounds and also text to speech voice. No more looking at the screen to know the current interval. Each timer is composed from intervals. Each interval has a configurable name, duration, color and music. Music can be set also for whole timer.

Your workout sessions can be saved into history where you can see how you performed during exercising.

Doesn't work in background

Overall it's a great app. It's easy to set up a variety of intervals and the workout feature lets you string together different intervals. Unfortunately since a recent iOS update it only works properly when the screen is on and the app is in the foreground. If the screen is off or the app is running in the background it doesn't signal the intervals on time. I told this to the developer a while ago and they got back to me right away but still haven't updated the app.

I love this app, but it is lacking some features

I love this app, but it lacks functions that many others have now implemented.
As much as I love this app, the lack of Apple Health integration, and not having an Apple Watch app, I am seriously looking at finding an alternate solution.

I used to recommend this app to all my collegues, but I can't do that any more.

If you implement these changes I would happily give 5 stars.

The BEST interval timer app. Period.

I was strugling to find a good interval app trying dozens of different timer apps, when I suddenly ran into this young an dedicated devteam, whom was ready to listen on what are the features takes an interval app a good one. I am using this app twice a day, as a part of my preparation training for a Trans-Atlantic rowing, and I can state, that the app not only has super clean interface, logical setup structure, but it does what its promise: realiable, verstaile still easy to use iterval timer. Best for all whom really want to train and improve there endurance. Since interval trainings are the best for your body, is a must for all, trust me, with 6 hours daily training, I can tell the difference. The support of this app is superior, I never got a response later than 48 hours, and all features/modifications were completed in no time. I am very happy both with the app and the Team behind.
