Dann Gerät ausgestellt. Abends am Handy stehen 0 Schritte. Ich mache das Gerät an. Aktiv Synchronisieren kann man nicht. Aktivität nicht protokolliert. Schade… ### 3/5 — Рекомендации по улучшению *2026-04-22, version 6.0.7* Приложение нормальное, но хотелось бы добавить одну функцию чтоб приложение учитывало только мою ходьбу а не всех кто ходит по дорожке. Если можно сделать персонализацию то будет отлично. И еще почему то у меня не работает функция учета пульса с эпл вотч. Перестало работать приложение и на телефоне и на часах постоянно пишет что б я подождала или отключила на 5 минут но ничего не помогает . Почините приложение пожалуйста ### 3/5 — Schlechter geworden mit Apple Health *2026-04-13, version 6.0.7* Eigentlich war ich richtig zufrieden aber seit einiger Zeit werden meine Trainings nur teilweise zu Apple Health übertragen. Wenn man die KS Fit mehrmals schließt und wieder öffnet kann es sein das sie dann erscheinen. Es wäre toll wenn ich einen Bitton hätte zum erneuten übertragen so fehlen mir wichtige Trainings in Apple Health und das mit einem Hochpreisigen Laufband sollte so nicht sein ### 2/5 — Ga bisa go *2026-04-08, version 6.0.7* Sudah konek ke mesin, tapi saat pencet go, katanya device blum siap suruh tunggu, udh tunggu lama masih sama ga bisa , dulu seblum updade bisa, skrg jd aneh ga bisa, karena remote lagi ga bisa pakai baru mau coba pakai app ks fit app iphone ini ### 2/5 — Steps are not syncing into Apple Health *2026-04-07, version 6.0.7* Steps are not syncing into Apple Health ### 3/5 — Bitte Apple Health Integration *2026-03-31, version 6.0.7* Die App funktioniert an sich, mir fehlt aber die volle Integration der Trainingsdaten in Apple Health ### 2/5 — Mileage not reported. *2026-03-19* I frequently have the mileage I walk not reported to the corresponding activity it logs in Apple Health. It reports the time and steps correctly, but frequently it doesn’t report the mileage. I’ve also noticed that if you start a workout with your Apple Watch and use the app, double reporting of activity happens. Another thing I noticed, unrelated to app function, there are also visible non English characters in the app, which makes it look suspicious. ### 4/5 — Smart Watch *2026-03-12, version 6.0.7* When can I add my smart watch to this app. It appears to not work. ### 3/5 — Great with one exception *2026-03-05, version 6.0.7* Works great. Pairs with walking pad and Apple health. Wish it had a pause function rather than stopping a walk altogether. ### 3/5 — Please add data reset option *2026-02-26, version 6.0.7* I recently bought a new treadmill and wanted to start tracking my progress from zero. Unfortunately, there is no option in the app to reset or delete total distance data. Previously, this account was used on another treadmill by more than one person, so the statistics are not accurate for me anymore. I also tried to delete my account and create a new one, but there is no such option available. Please consider adding a data reset or account deletion feature. It would really improve the user experience. ### 3/5 — Problem *2026-02-25, version 6.0.7* Impossible to modify programs since last update. ### 3/5 — Missing feature *2026-02-25, version 6.0.7* Cant pause, there is only option to stop which ends training ### 4/5 — Pas de bug *2026-02-24, version 6.0.7* Facile à connecter, fonctionne bien. Cependant petit bémol concernant le comptage des pas dans l’application santé. Une partie seulement des pas sont comptés dans l’application santé de manière automatique. Cela rend le compte des pas à la journée impossible à suivre. Si je fais par exemple 5000 pas sur le tapis je vais avoir 2800 pas dans l’application santé ### 3/5 — It warns you about losing background sync *2026-02-17* If you don’t keep the app open and the phone unlocked, it will give you a notification that you can lose sync by running it in the background. I can’t think of any other Bluetooth accessory that can’t run in the background. This seems like the most basic feature. Truth be told, it generally is OK, but sometimes it does lose its connection. They should not treat us as a feature… Recognize it for the bug that it is and fix it. ### 3/5 — Decent *2026-02-16, version 6.0.7* It’s a decent app. The only problem is the steps don’t sync with step apps or apple health which is annoying ### 2/5 — Can do better *2026-02-15, version 6.0.7* Connects to walking pad. However reliability is questionable. But an even bigger issue is this has access to health data on my iPhone. I have a set of scales that record the data onto the health app. However I have to manually enter my latest weight records. Why is that? It seems to be inept of the software!!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Can do better *2026-04-26, version 6.0.7* Connects to walking pad. However reliability is questionable. (This has changed to it stopping recording exercise data onto my iPhone). So to record my exercise sessions I have to manually select on my Apple Watch an Indoor walk. Another issue is this has access to health data on my iPhone. I have a set of scales that record the data onto the health app. However I have to manually enter my latest weight records. Why is this getting steadily worse? It seems to be inept of the software!!! ### 1/5 — Useless App *2026-04-20* The app is totally useless and fails to wake up the WalkingPad. Then when its awake it had difficulty connecting. Getting this thing to connect is always a 5 min process of starting, attempting to connect, restarting - absolutely ridiculous. Good luck using this thing without the remote. ### 1/5 — Sync issues *2026-04-01, version 6.0.7* The app isn’t able to sync properly with the device if not always left open and active. Also steps are not reporter properly into Health app. If you pause your run and start again you’ll miss on a big chunk of the steps done after that pause. And now it’s been 2 days that I can’t get the app synchronized with the device. Shouldn’t be rocket science to fix. ### 1/5 — Really terrible app *2026-03-11, version 6.0.7* Buyers regret - I should have looked at the software before buying the walking pad. The app consistently fails to connect to the app watch, it reads steps really wrong, writes to health kit incorrectly - who developed this app? It’s atrocious. ### 1/5 — Odradzam *2026-03-02, version 6.0.7* Po 3 miesiącach użytkowania usunęli konto, nie wiadomo dlaczego. ### 1/5 — App doesn’t work. *2026-03-02, version 6.0.7* App randomly logged me out and trying to log in or regain access to my account just doesn’t work which renders my walking pad useless. Garbage. ### 1/5 — Не открывается шаблоны *2026-02-24, version 6.0.7* Что вы сделали с приложением перестали открываться шаблоны и программы всё виснет ### 1/5 — Lock screen function *2026-02-09, version 6.0.7* It not completely black. My phone battery drained faster with lock screen function on.. please fix ### 1/5 — Big privacy red flags 🚩 *2026-02-06, version 6.0.6* Big privacy red flags 🚩 Extremely broad device identifiers collected Installed apps list accessed Clipboard access Location + Bluetooth + Wi-Fi combined Chinese law applies (government access clauses are wide) Revoking consent doesn’t erase past data immediately ### 1/5 — Unable to pair *2026-02-04, version 6.0.6* Simply does not find the device. I’ve done all troubleshooting steps and more and nothing helps. ## Most praised reviews (10 highest-rated) ### 5/5 — 생각보다 좋아서 놀랬어요 *2026-02-21, version 6.0.7* 나이키런 어플 쓰려고 했는데 그냥 이 어플 쓰려구요! 모든 것이 다 잘되어 있어요. 완전 추천. ### 5/5 — Widgets *2026-02-21, version 6.0.7* Please add Apple Watch widgets 🙏🏻 ### 5/5 — Good at Tracking+Controlling *2026-02-20* Tracks just like any other treadmill at the gym and lets you control pace easily. Don’t know why the other reviews said it doesn’t track because I was able to see my steps, mileage, and estimated calories burnt. I also easily connected the data to apple health. ### 5/5 — Enjoying KS Treadmill *2026-02-15, version 6.0.7* Great product, great app too ### 5/5 — Fixed problem with Bluetooth *2026-02-12, version 6.0.7* Recently had problem with Bluetooth connection on one of my devices, but I did some investigation in Reddit, Google and AI. I fixed it successfully as a reason was of the location of the phone so I changed the region at Phone from Italy to Ukraine and it works as expected. Thank you. ### 5/5 — Getting Better! *2026-02-09, version 6.0.7* Update, 2026/02/09: the last couple of updates seemed to have fixed the connection issues as my Watch has been reliably connecting to my Walking Pad. Thank you! =================== Original, 2026/01/05: I got my MC 11 treadmill the beginning of November 2025 and have been using it daily. I love my treadmill, but this app – especially on Watch – seriously leaves a rancid taste in my mouth, and is something to be desired. Many times, I just want to turn on my treadmill, open the watch app, tap ‘connect’, tap ‘go’, complete my workout, and get on with my day. Sadly enough, the update from a few days ago has only made the app worse. Now, every time I want to connect my watch to my treadmill, I have to force quit the app on my watch, unplug the treadmill, plug it back in, get my phone, re-connect the app to my phone, and – while the workout is in session – re-connect my watch. IT’S FREAKIN’ FRUSTRATING! Especially today as I just finished a 45-minute workout, and didn’t even get credit for it! that’s another downside: if you do a workout and the app doesn’t connect to your device(s), you can’t force sync the data from your workout device to the app. also, when the app actually does decide to work “properly“ (and you do more than one workout in a day), the KS Fit app shows all of your workouts as one session, but you only get credit for the first workout in the Apple fitness app… as if any other other workouts never existed, i.e., about a month ago, I did five 30-minute workouts in one day, but only got credit for one of them an Apple Fitness. the algorithm/functionality of this app really needs to be re-thought. Also, make the app compatible/universal with iPad. It’s 2026! 🙄 ### 5/5 — Hibátlan *2026-02-09, version 6.0.7* Ne féljetek az apptól, kb. minden hibáját orvosolták már. Tökéletesen tudja amit kell, és az apple health sync is műkodik. ### 5/5 — Walk n work *2025-12-22, version 5.9.13* So far good ### 5/5 — I really like 6.0 Upgrade version *2025-12-19, version 6.0* The UI in versions prior to 6.0 was very cluttered, especially the homepage, but this new version is much nicer and easier to navigate. ### 5/5 — It does what is supposed to do *2025-12-18, version 5.9.13* It turns on the belt. It tracks the activity. That's what I needed, in my opinion. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
