### 5/5 — Great for tracking cardio

*2025-07-07*

Simple to use. Appreciate the ability to launch from the phone and see my heart and zones on the large display.

### 5/5 — Great App!

*2025-07-05*

This app is awesome.  It excels at giving vision into what stages your BPM goes through during cardio workouts. Really clean way to make sure you hold effort in peak BPM zones.

### 1/5 — Don’t recommend

*2025-02-06, version 1.50.15*

Pretty useless unless you pay for features

### 5/5 — I love it, its awesome, motivating !

*2023-09-04*

Great App, i love it, very motivating.  No more coasting for me, this app makes me push my self a lot harder to get my splat points !

My wife goes to OTF, and i wanted something similar to OTC, but without having to pay $100+ per month + heart monitor.  This app works great with my Apple Watch.  So u wont have to buy a heart monitor.  (But u may have to buy a smart watch that measures your heart rate).  Luckily, i already owned a Apple Watch !

Give it a shot !

**Developer response:** Hey John, really appreciate the review! 

The app will support any heart rate monitor that can connect over Bluetooth as well as the Apple Watch. So, your OTBeat from Orange Theory or your Lionheart from F45, they will work with the app! 

Let us know how we can improve, we love user feedback. Support@pkfitness.com

### 5/5 — One Issue

*2022-11-18*

I’m a personal trainer and I’ve been using this app for two months now and I’ve had a very good success with it. There’s not much I would change with it that I would write in a review other than the icon will not load to Apple Watch face screen. You can find it in the mixture of apps that you have on your watch but you will not be able to move the icon to the home screen if that makes sense. Like I said, it’s not a big deal but if you want to get to it quickly - you have to look for it. Otherwise outstanding app!

### 5/5 — Great addition to my workout!

*2022-09-27*

This app has been awesome to keep track of my cardio and make sure I’m pushing myself when I need to. Great for HIIT too to make sure you’re heartbeat slows between bursts of energy. The app is easy to use, allows you to see the amount of time you spend in zones via graph and lights the whole face of your watch in colors depending on the zone you’re in to make it an easy check while working out. Would recommend to anyone looking for a useful training tool to add and take their workout up a notch.

### 5/5 — Great

*2022-01-29*

Love the live workout treadmill stats

### 3/5 — Cardio workouts, outdoor walk, workout and Elliptical

*2021-10-31*

Very good at tracking, a little inconsistent on how it prints out, especially on the outdoor walk. Once I got a path I took. But have never gotten it again. How did that happen?

**Developer response:** Each workout type records specific information. For example, the outdoor walk workout type will record a gps path while an elliptical workout will not. Go back into your history and see which workout type was recorded for the workouts where you are expecting a path. Reach out to us at support@pkfitness.com and we can help figure things out.

### 5/5 — Favorite Workout App

*2021-04-08*

Super easy to use. Gives me all the information I want during my workout with just a glance to my wrist. The summary email I get after is also really cool.

**Developer response:** Love it, thank you!

### 5/5 — Bike riding

*2021-01-20*

Best heart monitor..App ...love it on my Apple Watch

**Developer response:** Love that! Thank you.
