Just keeps saying server is busy ### 1/5 — Horrible *2024-12-04, version 1.2.9* It doesn’t work. Imposible to use ### 1/5 — App doesn’t update *2024-10-22, version 1.2.9* I get notices every day the app needs to be updated to fix bugs but the app doesn’t actually update! ### 1/5 — Pause button is gone *2024-09-24, version 1.2.8* I can put up with all the Chinese but was disappointed to see the pause button no longer pausing my progress but ending the workout and resetting the metrics. A pause feature is missing on both the remote and app during walking mode. ### 2/5 — Works as a remote, doesn’t track miles *2024-08-08, version 1.2.8* My remote’s battery died and wanted to be able to use the treadmill while waiting for my new batteries to come in, found this app, and it’s been an easy replacement for the remote altogether. That said, it doesn’t track miles. I don’t NEED it to, I really only got it for the remote function, but I was glad to have the tracking function when I saw it was part of the app, but it’s just completely useless. It stops tracking around 15 seconds, every time. ### 1/5 — Useless and faulty *2024-07-25, version 1.2.7* Not that costway care but app doesn’t work. Everyone has same problem. Why would they pay to make an app not work when it used to be fine? Company should not be allowed to sell in Australia ### 1/5 — Awful app *2024-07-02, version 1.2.7* This app is terrible. It worked for about a week, and now every time I try to connect to my treadmill the whole app shuts down. It doesn’t work. ### 1/5 — App crashing *2024-07-02, version 1.2.7* App is crashing and I m unable to use my treadmill. ### 1/5 — New version crashes *2024-06-21, version 1.2.7* I am unable to use my phone app to work the treadmill. This is frustrating, please fix! ### 1/5 — crashes after trying to connect with treadmill *2024-06-21, version 1.2.7* terrible app ### 1/5 — App won’t connect *2024-06-19, version 1.2.7* My Bluetooth remote rarely works so I rely on the app to control the treadmill. The update to 1.2.7 rendered the app useless as it will no longer connect to the treadmill. My treadmill is now unusable. Pretty frustrating!! ### 2/5 — App is crashing when trying to connect to treadmill. *2024-06-19, version 1.2.7* Since latest version was released, I can not connect to my treadmill. Every time I try connect through the app, the app crashes and closes. I have tried turning the treadmill off and on. Also redownloaded the app.. Please fix as I can’t use my treadmill without this.. :( ### 1/5 — App shuts down *2024-06-17, version 1.2.7* After update, my app keeps shutting down. I can't use the treadmill. 😡😡 ## Most critical reviews (10 lowest-rated) ### 1/5 — Worst app ever *2026-05-20, version 1.3.2* I used it twice with my treadmill and now is showing server is busy try again later. ### 1/5 — App “server busy please try again later” *2026-05-20, version 1.3.2* Ughhhhh. So irritating. I’m trying to go into the app to start my treadmill and it always says “Server Busy Please Try again later” It’s so annoying ### 1/5 — The server is busy *2026-05-20, version 1.3.2* I’ve been using my treadmill through the app for 2 weeks and suddenly today it won’t let me sign in keeps saying server is busy PLEASE FIX ### 1/5 — Worthless company *2026-05-19, version 1.3.2* They sell you an appliance with a physical remote that doesn't work so they can steal your data through an app that also doesn't work. Trash! And they know it! ### 1/5 — Horrible app *2026-03-04* Would not connect to internet and language came up in a foreign language. I’ve had this treadmill for a few years and app always was able to connect. Seems like something fishy is going on. Deleted the app. Do not trust it! ### 1/5 — Bad update *2026-02-04, version 1.3.2* New version is terrible. Cannot change treadmill speed reliably ### 1/5 — Mauvaise app *2026-01-23, version 1.3.1* C’est vraiment une application de base qui remplace la manette (qui ne se synchronise pas) avec mon tapis GoPlus. Après trois jours d’utilisation, impossible de continuer mon training, j’ai du tout recommencer. Impossible de créer son propre entraînement. Application vraiment inutile! ### 1/5 — Doesn't work *2026-01-19, version 1.3.1* Model isn't listed. ### 1/5 — Nonsense *2025-04-16, version 1.3.1* This is app is a waste of time and adds no value. Connecting is a pain, terrible localization, mileage tracking is buggy and impermanent. And no Apple Health integration so if you’re looking to get step/mileage data from this you’re out of luck. I suppose you can use the remote feature as a backup, but that’s not a big plus ### 1/5 — Useless app *2025-02-21, version 1.3.1* It's doesn't work as intended. I shows inaccurate distance and pace. I wonder if it's even working or just there for showoff. It doesn't sync with apple health or fitness. I don't understand why would anyone design an app that is not compatible with anything else in the first place. ## Most praised reviews (10 highest-rated) ### 5/5 — Fixed issue *2024-07-27, version 1.2.8* Thank you for quick response in fixing the issue where my iPhone kept exiting to its main screen when trying to connect to my walking pad , it works now thank you very much ### 5/5 — It works *2022-03-18, version 1.0.9* App works for the treadmill. Could be better, could be worse. ### 5/5 — Génial *2021-07-14, version 1.0.5* L’application est génial, par contre il serait bien de pouvoir contrôler le tapis avec l’Apple Watch ### 4/5 — Stuck on speed *2025-01-28, version 1.3.1* Recently my treadmill will not go past 2.5. How do I resolve this. Reset is not fixing it and the app doesn’t have an update ### 4/5 — Super fit treadmill *2022-02-03, version 1.0.9* Treadmill works great, but it connects my Bluetooth to random songs and people. There’s no option to connect to Bluetooth speaker available showing on my device. ### 3/5 — App is not working for a lot of us!! *2026-03-04, version 1.3.2* I woke up early today and the app is not working. We are all experiencing this currently please fix app ASAP. ### 3/5 — No Apple Health integration? *2025-05-13, version 1.3.1* The app works fine and can be used as the remote control, as well as tracking activities. But the exercise data doesn’t show up in Apple Health. :( ### 3/5 — lots of room for improvement *2023-05-10, version 1.2.0* I’m glad there’s an app to control the treadmill in case the remote gets lost. I’d love to see updates with some more features — syncing with Apple Health would be awesome so I could have all my fitness data in one place. It would be nice to be able to control the speakers from the app rather than having to pair them separately. An option to turn the beeping down or off would be great as well. ### 3/5 — Apple Health App integration not available *2023-04-21, version 1.2.0* 1. It would be better if it had apple health app integration. 2. Doesn’t show the step counts per day ### 3/5 — Functional but lots of room for improvement *2023-02-06, version 1.1.7* I hope they develop this further because there’s a lot of potential it’s just not there yet. I use it regularly and wish there were some quality of life improvements like muting the loud beeping from the treadmill or filtering the ranking of other people to just the people in your contacts. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
