The best interval timer app for IOS just got even better! Downloaded by over 100,000 awesome people just like you, Intensity is the workout companion you’ve been looking for. 

*** Now with Siri integration all new for iOS 11 ***

Before we tell you more, have a look at what people are saying:

“This makes HIIT effortless. You don't have to think about what songs to play or how many intervals you have done, it does it all for you.

“I downloaded this app to help with home tabata workouts and it is just what I was looking for. I love having my own playlist to keep me going through a tough workout!”

“What more could you want then your own personal music & timers to keep you moving!”

You love HIIT because it’s a quick workout style that you can easily fit into your daily routine. We agree, and would hate to see you squandering your valuable time screwing around with a lame, hard to use timer app. That’s why we built a workout timer so easy to use, even your technology-challenged family member of choice would adore it.

Download and get started in seconds with built-in curated workouts. Go deeper with the flexibility of the best workout builder on the app store, adding your own custom intervals, rests, warm-up/cool-down,  caloric burn, and music selection. Speaking of music, have it your way with tunes from your own music library or use music from other apps, Intensity runs in the background so you can continue your routine even while using other apps or putting your device to sleep. Subtle sound queues and text-to-speech interval  announcements will guide you through each workout. And of course, we know how important it is for you to make progress towards your fitness goals, so we’ve added a workout log as well as easy integration with the iOS health app.

Intensity - Your workouts, your way.

Nice app


Very straight forward



I have hundreds of apps, all useful to varying degrees. A chance download of TuneTime in my hunt for a seven minute work out timer has got me totally stoked. Its a clean, easy to use and understand interface. Extremely well thought out and above all exactly what you need for the seven minute workout. One final point. Its totally accessible using VoiceOver on the iPhone. Not sure if by luck or design, but I love it when developers like producing apps which are main stream, but accessible by people with disabilities they should be given a pat on the back. I have been an iPhone user since the three Gs and this is the first time I have felt completely compelled to rate an app. One minor feature enhancement I'd like to see is for the app to automatically choose tracks from Apple Music and other streaming services as it does now, but only over a more suitable BpM as the slow soft rock is really not doing it for me! 😆

Timer with music. No more no less.


This is just a simple timer linked to music. That's it. The paid for "workouts" are just settings for a timer. Don't be fooled into thinking you will get a structured work out. Take Tabata for example. For .79 you get a timer split into 20s:10s. You are unable to edit it so no titles of your exercises for example (just "go" vs "stop"). Compared to competitors (eg: seconds pro) I was surprised by the limitations of this app and feel a trifle cheated.
