  1. [R2] Strong Workout Tracker Gym Log 5/5 · US My 5 year anniversary: Starting using this in August 2021. And if nothing else, the fact that I’ve used it consistently during the last 5 years should speak for itself. I’ve logged 963 workouts in the app. It makes progress easy to track, the watch sync captures my hr data and the features such as sticky notes, adjustable timers and failure/drop sets really do cover eventuality for me. Can’t recom
  2. [R5] Strong Workout Tracker Gym Log 4/5 · US Almost perfect: The exercise catalogue is impressive and you can create custom exercises if you can’t find what you need. My biggest complaint is that sometimes the watch app doesn’t sync and then you need to remember what you did to log it correctly on the phone app. And it seems you need to be connected to WiFi for the watch app to sync, which is incredibly frustrating.
  3. [R8] Strong Workout Tracker Gym Log 5/5 · US My workout partner: I use this app in every single workout. I can’t remember the weights and repetitions and seeing them precisely allows me to see progress. I love the ability to create my own templates when I get too comfortable with my workout I create alternate templates to explore, newer types of exercise, like body, weights, or kettle balls, or any number of things.
  4. [R14] Strong Workout Tracker Gym Log 5/5 · US Phenomenal: Nearly 700 workouts done using this app. Absolutely a beast at tracking sets. The graphs monitoring progress over time are super helpful as well. Definitely recommend!
  5. [R23] Strong Workout Tracker Gym Log 5/5 · US Fantastic workout partner: I’ve been using Strong for over two years. I now have a huge record of specific workouts and exercises and can see my progress. Super easy to plan workouts and record exercises.
  6. [R30] Strong Workout Tracker Gym Log 3/5 · US Laggy text entry: Used to work great, tried again recently and finding that nearly every time I enter in the weight or reps for an exercise it lags and I have to do it over.
  7. [R32] Strong Workout Tracker Gym Log 5/5 · US Amazing for it being free: Been using it to track workouts for the past 3 years. Very intuitive interface and very generous for it being free. No ADs either which is a plus. Great history and tracking features as well
  8. [R35] Strong Workout Tracker Gym Log 5/5 · US Fantastic!: I have been using it for 9 months, I have 199 recorded workouts. It is really easy to navigate from my apple watch, I don’t need to use my phone when at the gym. Great to see the visuals on how to perform an exercise. I only wish it had a record for tracking the amount of perceived effort for each set. But, I tried many others, this is fantastic and have recommended it to many peop
  9. [R1] Strong Workout Tracker Gym Log 1/5 · US It stinks now: It used to sync well with my watch. Not anymore. Almost useless.
  10. [R4] Strong Workout Tracker Gym Log 2/5 · US Buggy: Today is my first day working with this app. I’m entering custom exercises to build my first routine. The app has frozen several times and needed to be restarted.
  11. [R3] Strong Workout Tracker Gym Log 3/5 · US Hevy Free version better: Hevy app gives more options, insights and charts than this app. The free version is not sufficient and would need us to pay for it to be usable
  12. [R10] Strong Workout Tracker Gym Log 2/5 · US Buggy, even with the paid version: This app is incredibly inconsistent, especially when it comes to syncing up to my Series 11, sometimes it absolutely refuses to communicate with the watch and vice versa. The timers between sets often freeze or don’t engage at all, it throws in random numbers for weight and reps into my workout templates and a large amount of my recorded sessions seem to disappea
  13. [R18] Strong Workout Tracker Gym Log 3/5 · US Good app. Poor sync.: I’ve used this app for years to track my workouts. Overall, it’s good when it comes to tracking workouts, but the sync feature between the app and Apple Watch can suck. Sometimes it syncs fine and other times they won’t sync unless you reset the app on both the phone and Apple Watch. This issue is persistent enough to where I experience it on a pretty regular basis. I wouldn’
  14. [R7] Strong Workout Tracker Gym Log 2/5 · US The workout app field is expanding rapidly and Strong is getting left behind.: I’m quickly finding that there’s no perfect workout app. There’s always a these things are great or improvements over this app…but…and the “but” is the key because it comes down to which app is offering the trade offs you’re willing to live without? My frustration with Strong is we are still dealing with syncing issue
  15. [R11] Strong Workout Tracker Gym Log 5/5 · US Best Workout Tracker: I have been using Strong daily since 2017 and because of its compatibility with my Apple Watch, I will go no where else. They have continued to develop the app and are quick with bug fixes. It has everything I can think of to track my workouts and progress. It is the main reason for me keeping my Apple Watch. I have the lifetime membership.
  16. [R13] Strong Workout Tracker Gym Log 1/5 · US Junk app: If you ever have to reach out to the developer team, know you’re in for zero help. This app has constant issues integrating with Apple Watch which, for a fitness app, renders it useless. Every time I reach out to support they just tell me to uninstall and reinstall the app. If that was going to work, don’t they think it would’ve worked the first time? They’re lazy and uninterested in mak
  17. [R24] Strong Workout Tracker Gym Log 3/5 · US A Former Great: I used Strong for years and it was a great app. Unfortunately the devs haven’t kept up with the times and recent sync issues with my Apple Watch have caused me to switch to a different app. Will it do the basics and do it well? Yeah. Are there much better, more feature rich workout apps? Also, yeah.
  18. [R47] Strong Workout Tracker Gym Log 1/5 · US Mediocre UI: UI is mediocre. Only 3 free templates and a $99 lifetime license. Get a $1 notebook and a box of pens. Your iPhone already has a timer. App is free otherwise to see the prebuilt templates.
  19. [R51] Strong Workout Tracker Gym Log 2/5 · US Templets: You should let people do more then three templets without the pro I know your trying to make money but like four not three you guys are just trying to take money from people
  20. [R25] Strong Workout Tracker Gym Log 2/5 · US No Longer Updating: The app is good except for the fact that is seems like they've stopped caring or updating the app. The list of workouts in their database is extremely limited. You can add your own, but they don't allow you add any images/ videos/notes for reference. I think with ALL the apps out there, they should be updating their list of workouts weekly to include visuals and notes. Or at
  21. [R36] Strong Workout Tracker Gym Log 3/5 · US Okay: Decent at tracking workouts that exist. Very limited options to create custom exercises. And you cannot edit or delete them? What is this buffoonery?
