### 5/5 — It’s a Simple Interval Timer

*2026-07-31, version 5.1.2*

This kind of app does not need a monthly subscription or a load of bells and whistles - it just needs to be basic and work. Which is exactly what this app does. 

Easy to use, with a nice customisable widget. Zero complaints.

### 5/5 — Does exactly what it’s meant to do.

*2026-07-27, version 5.1.2*

Does exactly what it’s meant to do. It works perfectly for running a given time period followed by a given walking time period. Great for plantar fasciitis programs prescribed by your PT.

### 5/5 — Straightforward and effective

*2026-07-26, version 5.1.2*

This app makes HIIT workouts easy to maintain. A real boon to anyone serious about maintaining fitness.

### 4/5 — Simple but Annoying …

*2026-07-13, version 5.1.2*

I love this timer because it’s straightforward and simple. I love how it will tell you when to walk and run. Using this for my training block this summer. However, it’s frustrating and annoying when if you need to stop in the middle of the run it doesn’t pause automatically. Actually, it doesn’t pause at all manually either. I tried pausing it yesterday when I needed to use the bathroom. My 2 other run apps will pause automatically when it senses I have to stop. 

If the developers of this app can figure out a way to make it pause automatically, I will give it a 5 star rating and purchase the upgrade.

### 5/5 — This is how apps should be

*2026-06-27, version 5.1.2*

I don’t need my interval timer to win a design award. I just need it to work — and this one is great! No bloated features, no flashy UI trying to impress me, just a clean, functional tool that gets out of the way and lets me focus on my workout. Honestly, more apps could learn from this approach. Simple is hard to do well, and the developer nailed it.

### 4/5 — My “go-to” for interval

*2026-06-14, version 5.1.2*

This has been my go to for interval training for several years. It could be improved, but everything can be improved and I did this able to handle all basic intervals. If it could be programmed for multiple variations at once that would be awesome.

### 5/5 — Simple free and works great

*2026-06-12, version 5.1.2*

All the others wanted a lot of $$$s this one does the job. Thanks

### 5/5 — Just what I needed

*2026-06-07, version 5.1.2*

Simple, effective, free

### 5/5 — Great app!

*2026-06-06, version 5.1.2*

I love this app! It’s good for my workouts, I use it all the time. One thing I really want is for it to get updated daily to work well with the latest future iOS updates.

### 5/5 — It’s perfect

*2026-06-03, version 5.1.2*

It’s so refreshing when an app is t trying to drain you wallet or distract you. Long live function!!
