April 15, 2023 | Version 1.0.5

I was in a dilemma for quite a few days, wondering if I should subscribe to FitOn Pro. The main reason why I’m thinking to subscribe is to connect with my Garmin, yet a lot of negative reviews are written for Garmin’s FitOn app. I decided to give it a try anyway, and I’m so glad I did. It records my heart rate smoothly during the workout so I can keep track of it, and they do record your finished workout on Garmin so it’s all connected! You can only see heart rate and calories burned for the data on each workout though, but I’m happy with that. I don’t usually give reviews, but I think I should do justice for FitOn based on my experience. Hope this helps! :)

As it is, it’s useless…did not work in any of my workouts…last update was in August 2022!!

March 28, 2023 | Version 1.0.5

Heart rate gets stuck often and ruins my workouts.

Sabina De Lorenzo
March 16, 2023 | Version 1.0.5

Agree with everybody else, the heart rate suddenly disappears and it stops measuring and recording the sessions. Let's not even start with counting the steps. However I believe the issue is with Garmin and not Fiton. Sadly, we all have the same issue but the bug does not seem to interest the developers.

February 14, 2023 | Version 1.0.5

It often stop measuring my pulse after few minutes. Pretty annoying, because it seems like its the only feature of this app. I quickly change back to my standard measuring apps.

Nicole S J

I think you need to have FitOn Pro to have comparability.

January 29, 2023 | Version 1.0.5

This app does nothing. The design is incorrect. It does not update FitOn. A server to server integration like Strava or Apple Health is the correct way to build this.

Kelly Zara

I LOVE FitOn, I wish Garmin would improve connectivity with the app! It only recorded 1 of my workouts in the last couple of weeks. I'm not sure what the issue is

Same here, app not connecting to the phone. I need to Link my device every time I start a workout in the Fiton app on my phone. The phone should connect to the watch automatically.

Sharon Bennett
November 26, 2022 | Version 1.0.5

So, I get my heart rate showing on my watch. Now what?! Completely useless.

Lakecia Allison
November 21, 2022 | Version 1.0.5

It is laughable and irritating AT THE SAME DAMN TIME! It doesn't record any workout you do on the app! Just records heart rates!!? Like seriously!? Just remove the app and trash it!

Juanita N
November 3, 2022 | Version 1.0.5

I have the app installed in Connect IQ but when I try to link my watch in the Fiton app it keeps saying Application not Installed.

September 27, 2022 | Version 1.0.5

So disappointing. Doesn't post workout at all. I can get my heart rate from other apps.

Mark Johnson
September 26, 2022 | Version 1.0.5

It doesn’t do anything apart from show heart rate

Tony Bouchard
August 22, 2022 | Version 1.0.5

Ne fonctionne pas du tout juste un logo :(

August 20, 2022 | Version 1.0.5

Doesn't connect to the app, just shows HR on your watch!

July 17, 2022 | Version 1.0.2

Like many others find the integration hit and miss, mainly miss. Half the time it makes my watch restart midway. Rarely syncs the workout, usually end up adding a manual activity into Garmin connect. Disappointed as this was a major reason I paid for Pro!

Mariana Ballina
July 15, 2022 | Version 1.0.2

50/50 chance on whether it will actually record a workout on Garmin Connect. I will connect via fiton AND my watch, and it will show correctly on my watch. Sometimes it works fine, and then there is just a 15 second lag once my workout is done to auto stop the activity and save. But the other 50 of the time, at some point throughout the workout it will just stop midway through without warning, and you're left with nothing. Given that it only tracks your heart rate, and the integration with the fiton app is minimal, I'll probably just switch to starting a strength activity through Garmin the traditional way.

July 13, 2022 | Version 1.0.2

The worst app in the history of mankind. Doesn’t record the workout. Stops during workout without any warning of indication

Jakub Vrana
July 13, 2022 | Version 1.0.2

After few workouts, app stop adding workouts to Garmin connect. On watch show only HR. Pls. add more data fields like calories, time, real time etc

Selina Esquivel
June 29, 2022 | Version 1.0.2

I don't know what the point of this is.. my heart rate isn't even accurate. I expected this app would track the workouts in the app& record them accordingly. This is just a waste

June 12, 2022 | Version 1.0.2

Only picks heart rate, but doesn't show calories burned!

April 26, 2022 | Version 1.0.2

It's just a heart rate monitor that won't even connect to my fiton.

April 25, 2022 | Version 1.0.2

I can’t even get my to connect. It shows my watch as an option but it keeps telling me to (re)open the app, which is already open or has already been reopened. It’s just not working for me. And it was also the reason I went Pro. Very disappointed. Won’t be renewing my subscription.

Erwin Roossien
April 2, 2022 | Version 1.0.2

What a letdown.. I was hoping Fiton workouts would actually register on Garmin Connect. But all it does is show your heart rate in the Fiton app and even this sometimes gets stuck. One of the reasons to go pro was because of the 'compatibility' with Garmin but it's just a fancy heart rate monitor atm.
