Interval? in IOS

A music-training game

Our Expert Score

82/100

Interval (or Intervals Pro) is the gold standard for workout timers on iOS. It’s rare to find an app that is this powerful yet stays so user-friendly. I’ve used it for everything from high-intensity interval training (HIIT) to Pomodoro study sessions, and it excels at both. The way it integrates with Apple Watch is a game-changer; being able to leave my phone in the locker and get haptic prompts on my wrist for the next set is worth the download alone.

The customization is what sets it apart. You aren't stuck with basic 'work/rest' cycles. You can name every interval, assign colors, and even have the app announce the name of the next exercise via voice prompt. It turns your iPhone into a professional-grade gym timer. If you're serious about your training and timing, this is the app you need.

Various updates and improvements.


Challenge your musical skill with Interval by determining which chord was played. For each puzzle, three chords are played with the musical notation displayed for the first two. The third chord will be one of four choices displayed - choose your answer by touching the right chord. The point value for each game will be added to your score for the correct answer, but half the points will be deducted for each wrong one. You can play the three chords as many times as you like, and you can move on to the next puzzle without answering and without penalty. Your musical knowledge will increase with repeated playing of the game.
