Sort it out please. Apparently you don’t exist half the time. It’s definitely you not us! ### 2/5 — Not happy customers *2025-02-28, version 3.4.3* Was a good app, now customers having constant issues trying to book due to demand. Needs fixing as it’s an absolute stress for all users at the moment and create huge amount of gym class user complaints. ### 1/5 — Rubbish *2025-02-15, version 3.4.2* This app has crashed so many times. I think every week I am sending a ticket request to fix the problem. Logs me out and then when I log in it says ‘server error’ so annoying when you’re trying to book a class. ### 1/5 — Awful *2025-01-02, version 3.3.0* Can’t even configure the app to send a simple password reset link. Tried over 10 times to reset my password and have never received a reset link. ### 1/5 — Update is rubbish! *2024-11-25, version 3.2.6* This app was excellent. My phone auto updated to the new app on Friday. Tried to book a regular class with my gym this morning and won’t load at all! Keep getting an error message ‘failed to contact the server in a reasonable time’. It also says ‘you have no upcoming sessions this week’ even though I have 2 booked. Turned off phone and still the same, will delete app and download again to see if that fixes it but shouldn’t have to do this! ### 3/5 — Good but with one glaring issue *2022-07-11, version 2.2.1* You should not be able to book a class when the cancellation window for it has closed in my opinion. My phone is broken and as a result I booked a class that I'm not going to and cannot cancel it because it is outside of the cancellation window ### 2/5 — Slow and poor search *2021-07-06, version 2.2.1* The system is slow to access the class options and often gets a server error before completing a booking To find a class you have to scroll through all classes in time order - adding a favourites or some way to navigate to specific classes ie squash or swim would really help make it easier to use. ### 1/5 — Not Great *2020-08-08, version 2.1.7* The app doesn’t work and had to ring the gym to book a session because I keep getting a error message saying the gym has to authorise it. Shame could be really good app, as was recommended by the gym itself. ### 1/5 — Don’t bother *2020-07-12, version 2.1.7* This app has the potential to be great. It is let down by glitches in log in and lack of back up customer service. If you forget your password. Please try again later. Not good if you need access to check in. GymInstructor isn’t much much good and lacks detail. I would of happily paid the monthly subscription if it was all sorted. ### 1/5 — Does not work *2020-01-27, version 2.1.7* I have been a member of my gym for 3 years and tried using this app so many times. I have to use the desktop version because the app has never let me log in. I have logged tickets with the support group and I was initially advised that the issue had been escalated but never heard back. Not fit for purpose. ## Frequently asked questions about GymSync ### Does GymSync work with any gym? No, GymSync only works if your specific gym is currently using the GymSync platform.
