Great app for intervals. Best part is the upload a photo and adjust for user. Easy quick use. Now only con for me is, I am a calorie and stat person. It will sync to apple health. But no track of calories, heart rate average, and workout details when it syncs. I use Strava and like this app. But when it comes to this app no stats. Fix this and I will change to a 5. **Developer response:** Hi there - thanks for the feedback and were glad you like the app. One clarification - app does support tracking calories and heart rate when paired with an Apple Watch and the watch app is used and connected to the iPhone app during the workout. Hope that helps! ### 1/5 — Terrible just terrible *2026-02-19* It’s just AI slop. Timer is glitchy, asks for a subscription and like what exactly am I supposed to be paying you for. The AI voices are jarring, your phone buzzes like crazy if you have haptic feedback turned on, there is no way this wasn’t made in a week. Not to mention this looks like a rip off of a different timer. ### 5/5 — INCREDIBLE APP!!!! *2026-02-18* This is exactly what I needed and is beyond amazing!!! **Developer response:** Glad you like it! ### 1/5 — Paid timer *2026-02-16* Wtf. I’m not paying a subscription for a glorified timer. Fo. Junk. ### 5/5 — Really Helpful *2026-02-02* This timer keeps me on the mark. I use it to walk three minutes. Slow three minutes fast, for a total of 30 minutes. Prior to this I was trying to wash the clock, which wasn’t always successful. And I tried different apps that didn’t work as easily as this one does. Worth it. **Developer response:** Thank you for your feedback - glad you like it! We just added a voice queue for half way mark too! ### 1/5 — Why does this cost money?? *2026-02-02* Only allowed me to do 3 workouts before making it a pay wall app **Developer response:** Hi there - thanks for the feedback. The app does have costs and is actively developed and maintained which requires charging a very small amount. If it provides you value, I hope you reconsider - I believe this is the best app out there for interval training - and will keep getting better! ### 1/5 — App crashing every time I open *2025-10-01* Could never get passed the opening screen **Developer response:** Sorry about that, this has now been addressed! ### 5/5 — Great app *2025-08-23* I looked for a great workout timer app and this one is perfect. Simple to use, easy to save workouts. Highly recommend. **Developer response:** Glad you like it✌️ ### 3/5 — Close but too buggy to use *2025-06-28* This is the best timer for my needs, but it’s unusable since it adds extra time that I didn’t configure. Also when I try to save a timer, the timer doesn’t save correctly because it adds extra rest time or doesn’t save updates. I’ll pay the yearly if these bugs are fixed, but for now, I’ll continue searching **Developer response:** Hi - sorry you’re experiencing issues! We just published an app update that fixed the issue. Let us know if you are still experiencing it after updating by contacting us via the app! ### 5/5 — Great for simplicity AND great info! *2025-06-23* Not too simple yet not too complicated! I’ve tried DOZENS of apps looking for just the right mix. This app gives me the simple tools with tons of information! Kudos! **Developer response:** Glad you like it! ## Frequently asked questions about Interval Timer HIIT Workout ### What does the Interval Timer HIIT Workout app do?
