User reviews

Great for tracking cardio

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

Great App!

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.

Don’t recommend

Pretty useless unless you pay for features

I love it, its awesome, motivating !

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 !

Response from developer

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

One Issue

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!
