### 1/5 — Pointless

*2024-07-07*

Won’t run in the background. Stopped the interval when the phone was locked or I shifted to another app

**Developer response:** I actually put that in by design. Next time I do a software update I can put in a setting to have it run in the background.

### 4/5 — Good app

*2024-06-30*

Provide more color options for the intervals and the ability to type the time rather than scrolling and this app would be great!

### 5/5 — Day 2

*2026-01-03*

This is my second day and I am so HAPPY! I have been searching for 2 weeks for an app like this.  THANK YOU

### 5/5 — Easy to Use

*2025-10-08*

I’ve been using this timer for over a month now and it’s been great and no problems at all. I can create multiple workouts with different intervals and add the names of the exercise if needed. 

The only improvement that I would like to see added is a countdown timer letting me now how much time is left. When you create a workout, the total time is displayed, but when you actually workout you don’t know how much time it s left. Other than that, it’s perfect.

### 5/5 — Love it !!

*2021-04-11*

Love this app. Very easy to use and I can hear the beeping in the loud gym. I would be nice if they had an option to share our workouts with other HIIT app owners

**Developer response:** Hi! Thank you so much for the review! You can share workouts from your workout list screen by swiping to the left on a workout, choosing the green Share icon, and then either emailing or AirDroping the workout to friends.

### 5/5 — Great app

*2021-02-21*

The app has great functionality and options.

### 5/5 — Flexibility

*2021-02-16*

I love having the ability to customize, not only the type of exercise, but the interval length and the number of repetitions.  This app has become an exercise game changer for me!

### 5/5 — Great for customizing workouts

*2021-02-06*

I love being able to enter the names of my exercises and customizing length of intervals.  Once all my workouts are created and saved, it will be so easy to select which one to do each day, open, and begin. I like the new feature of being able to send my workouts to other app users. The look of the timer is awesome.
