About this app

We are three friends who love high intensity interval training. But we couldn't find an interval timer app we liked, so we created one ourselves that we love ❤️.

💪 Features of Hiitmi (free version) 💪

🕺 No ads at all
♾️ Unlimited number of created timers
💃 Easy and fun to use
📤 Create your own workout and share it with your friends
🎵 Training with music: just use your favorite music or podcast service (Spotify, YouTube, etc.)
👩‍🚀 Energetic and motivating female voice
🚨 Beep sounds for use in noisy environments
📈 Keep track of your workouts with simple statistics
🕶️ Choose between light and dark theme
📳 Vibration
📺 Add video URLs to your workouts

⚠️ In order for Hiitmi to work when the screen is off, a setting is necessary on Samsung, Huawei, OnePlus and Xiaomi devices. More at www.hiitmi.com/dontkillmi.

The app is in English, with English voice.

We received many wishes for additional features, and also the wish from some users to support us financially. So we decided to introduce a subscription based Pro version that provides additional features. This way we can keep Hiitmi ad free and independent. We thought the price of about one coffee ☕ per month would be fair.

💪 Additional features of Hiitmi Pro (paid version with subscription) 💪

Great app! I use this for interval training, getting back into running, have been using it for about 9 months and am really loving it. Also, I sent some feedback, making a request for a minor adjustment, they sent a response thanking me for the feedback and not only did they make that adjustment in a release (I'm sure I wasn't the only one that would find it useful) but they emailed me back saying it was made. I feel like interactions like that with a company are so rare anymore! Love it!

I just installed this app on my Samsung A50 smartphone. It installed flawlessly. I configured my own interval training for running. One was for 6 intervals of hill running at 30/60 work rest intervals. A second was for 8 sprint intervals including a 20 minute warm up and 15 minute cool down with 1 min sprints and 2 minute rest for a 57 minute hiit workout. The voice notifications were loud and clear. I have installed and uninstalled many HIIT apps. This one is the best I have found. And it's free with no annoying ads.

Dear Genesio glad to hear that you were able to adjust Hiitmi perfect to your running intervals and that it convinced you the best among all the available apps. Thank you very much for your words of praise. We would be happy if you could recommend Hiitmi to friends/colleagues. Good luck and have fun training with Hiitmi. Your Hiitmi Team

I rarely make reviews being too lazy for it. But a very few apps don't deserve to be not reviewed when it excelled over most others. For having a built-in voice feedback alone, this belongs to a few exceptional apps. Not to mention you can customize your own sets, and having a separate warm-up set that goes along with cool-down (most others only have the latter) and all those features accessible for free. It caused me to uninstall all other hiit apps I tried. This is tops! 06.10.25 pls add reps.
