What users complain about in fitness tracker apps

The complaints that repeat

Each heading sums up what reviewers wrote; the quotes under it are their own words.

1. 01

   Unreliable smartwatch synchronization and lost workout progress across Fitbod, Fitlist, and Strong

   Many users

   “-1 star for not being able to RELIABLY go between my Apple Watch and phone to track progress or complete sets or workouts.”

   “Today I did an 1 hour and 45 minute workout but Strong doesn’t show I completed this workout so I have no record of what I actually completed today”

2. 02

   Aggressive subscription billing, unexpected annual charges, and refusal of refunds in Fit AI and Gym Life

   Many users

   “Instead you need to lease the app by paying $60 yearly if you want to get any true use out of it. App is totally hobbled without the subscription.”

   “I decided to cancel the suvscription , so they won't charge me for the next year. My current subscription is funushing in March 2027. Now when I am opening app , it straight away suggests me to subscribe”

3. 03

   Arbitrary paywall limits on routine creation and core logging in Strong and Gym Life

   Several users

   “I just need 5 different schedules and this app only lets you make 2 before having to get an “elite” subscription.”

   “My biggest complaint is that I can only create three routines without upgrading. I wish there were a way to pay a flat fee for a few more services”

4. 04

   Buggy workout creation and inability to add or edit supersets in RepCount, Fitlist, and Hevy

   Several users

   “When working through a superset, the app thinks I’m finished before I’ve completed all the sets. Sometimes it will just stop toggling back and forth between the two exercises in my linked set.”

   “Then going back in and editing it to be able to add sets or more exercises all the buttons in the UI of the routine would not let me add more sets or exercises after adding one or the other.”

5. 05

   Data loss and disappearing historical tracking data over time in Fitlist and FitNotes

   Several users

   “After about six months, it started randomly dropping weightlifting totals a few days after they were entered, showing zero pounds and reps on days when I did full workouts.”

   “Cons: no way to import or export data, data gone if switching devices- only needs a backup method to gain 5 stars.”

What users ask for

• Barbell plate math calculator with percentage of one-rep max

  Asked for once or twice

  “Feature request: on the plate calculator, please add a percentage field. I would like to enter a weight, enter a percentage (e.g. "85" %), and be able to see what weights to load onto the bar.”

• Mixed weight units (lbs and kg) supported within the same workout or gym profile

  Asked for a few times

  “It would be really great if you could switch between lbs and kgs for weight entry, from one session to the next -- yet have the weights recorded and displayed consistently.”

• Carryover and persistence of previous workout notes into active sessions

  Asked for once or twice

  “It's imperative that previous notes copy over and remain editable so we can easily update them!”

• Visual guides such as exercise demonstration pictures and GIFs for beginners

  Asked for once or twice

  “I do wish they'd allow you to add a picture or gif to the workouts. Such would let us newbies see what equipment to go to more easily and even add a gif showing how to use it.”
