HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (22 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

WHAT THEY COMPLAIN ABOUT · SHARE OF BAD REVIEWS
Worse after an update31%

61 of the 1 and 2 star reviews.

★★★★★ This latest update is AWFUL!
★★★★★ BUT, after a recent update, the app suddenly let me know that sensor support now required a $20/yr subscription.
★★★★★ update: I lowered this to one star because it appears after some experimentation that now you have to pay annually for any sensors, including just your apple watch heart rate.
Bugs, things not working22%

44 of the 1 and 2 star reviews.

★★★★★ It displays error messages when I try to start a workout, and won't load workout routines, including fitness assessments so you can even see where your HR zones are at.
★★★★★ App used to be great. Now the entire workout it keep connected and disconnecting from my Heart rate monitor. Very annoying and inconsistent. Had to delete
★★★★★ My iPhone was broken and I had to reset everything including my appleID (long story).
Lost data, sync, backup22%

44 of the 1 and 2 star reviews.

★★★★★ I'd pay $100 USD for a workout tool that doesn't have a sociopathic need to sync (aka share-steal) my data across my devices and doesn't have a EULA with a so-called “Privacy Policy”.
★★★★★ The first time I didn't notice it had disconnected and so I lost about 20 minutes of tracking before I realized.
★★★★★ I have an iPhone 12 and Apple Watch 6 and despite ensuring the global and local settings are correct (40th time to make this adjustment), the watch and phone app can't stay in sync and everything stops tracking after…
No customer support17%

34 of the 1 and 2 star reviews.

★★★★★ Anyway, I paid the yearly fee for pro and now there is no way to reach customer service through the web site or the app because it won't let me I.
★★★★★ BUT, after a recent update, the app suddenly let me know that sensor support now required a $20/yr subscription.
★★★★★ I tried to find a place to get support from iCardio and posted a question about this issue but never received a response.
Price and subscription16%

31 of the 1 and 2 star reviews.

★★★★★ Disappointed to see such a great app become totally unusable, even more so since I'm not sure I'll be able to get a refund for the subscription fee.
★★★★★ A while ago, I bought a lifetime ad-free subscription to iCardio.
★★★★★ not worth the subscription so many better options that are actually free
Crashes and freezes13%

25 of the 1 and 2 star reviews.

★★★★★ It displays error messages when I try to start a workout, and won't load workout routines, including fitness assessments so you can even see where your HR zones are at.
★★★★★ I'll give them more money." The best companies will even freeze the existing code branch and allow people that already have purchased the app to stay on that with minimal maintenance updates, and then will introduce an…
★★★★★ Heart rate reading freezes up on app.
Wrong or poor results11%

22 of the 1 and 2 star reviews.

★★★★★ The images are now blurry, and when you click for help options, it loads a full-size webpage that isn't designed for mobile use and is hard to read through all of the popups.
★★★★★ But taking away existing functionality from the people who bought your app and supported you in the very beginning was just wrong...
★★★★★ Now I have a useless app.
Login and account problems7%

13 of the 1 and 2 star reviews.

★★★★★ No, you also need a Fitdigits Account.
★★★★★ Today it constantly interrupted my workout with ads and marketing tactics to try to get me to buy an account.
★★★★★ No reason to require a login

Trouble connecting to watch…Always!!

Always having trouble connecting to Apple Watch. Each device claims the other is not in range. Never had this problem with iwalker….never.

★★★★★Dec 27, 2025
Great Workout App!

I have used this product since its inception to track my workouts and have zero complaints. looking back at the saved results, I have logged over 2000 workouts since 2010. It tracks the type of workout from weightlifting to elliptical to open outdoor activities (think yard work) to open indoor activities (think vacuuming or cleaning a bathroom). It tracks the amount of time, calories, and even effort. If you are outside, it will map your route. The app works with my iPhone and my Apple Watch seamlessly. It also connects to my Polar Heart-rate monitor while it is connected to my elliptical. Note: I do find the heart rate strap to be more accurate on the calorie burn than the watch, but you can choose whether the app uses the watch or strap for your heart rate tracking.

No longer functional in 2025

I used this app extensively 10 years ago. Unfortunately, after redownloading it again, it’s completely nonfunctional. It displays error messages when I try to start a workout, and won’t load workout routines, including fitness assessments so you can even see where your HR zones are at. The images are now blurry, and when you click for help options, it loads a full-size webpage that isn’t designed for mobile use and is hard to read through all of the popups. I tried uninstalling and reinstalling the app, and now it’s displaying error messages during the setup process, too, so I cannot even reach the main home screens. Disappointed to see such a great app become totally unusable, even more so since I’m not sure I’ll be able to get a refund for the subscription fee.
