It will often not submit and reset all of your progress. Does not allow you to change the weight in the application. ### 3/5 — Quirky *2026-01-13, version 2.0.14* I use it but when I decide to change the weight, it doesn’t let me. So frustrating. Also, the date is wrong. ### 1/5 — Totally unreliable *2025-12-15, version 2.0.14* How is this app still so bad? Almost every time I use it, it either cannot connect to the server, or even worse crashes when I try to submit my workout. It’s gotten to the point where I have to take screen shots of each page of my workout so I can submit when the app decides to start working again. This doesn’t seem like a difficult product to maintain. So what is going on??? ### 1/5 — Create account? *2025-12-10, version 2.0.14* I would like to use this app, but there is no way to get in touch with Support to create an account. ### 1/5 — Buggy *2025-10-03, version 2.0.10* In theory this app is pretty great and that hit balance is your workouts to hit all muscle groups, to use different methods to work the same muscle groups etc. And it increases the workload very gradually. HOWEVER, the app itself is always rife with bugs. Either at duplicates all your workouts, or doesn’t let you submit them, and rather just resets all the workout data that you’re already entered… Or it won’t let you change the weight for the exercise exercises, even though it offers a pulldown menu to do exactly that… Every time you do it it’s just revert back to what it wants. A lot of just app coding errors like that. Wish it could be better. Also you are not allowed to give feedback directly to active trax, you have to do it through your gym, and they aren’t always cooperative or interested. ### 2/5 — Never loads *2025-09-25, version 2.0.10* Decent app when it loads but more often then not, get to the Y ready for workout and it won’t load. Kinda useless when it doesn’t work regularly. ### 1/5 — Fix it! *2025-09-06, version 2.0.10* Latest update shows the developer did not test it before posting it for use. Obviously they don’t use it themselves. ### 1/5 — Buns *2025-08-19, version 2.0.9* Nothing works ### 2/5 — Never loads *2025-08-03, version 2.0.7* Decent app when it loads but more often then not, get to the Y ready for workout and it won’t load. Kinda useless when it doesn’t work regularly. ## Frequently asked questions about ActivTrax ### What does ActivTrax do?
