First world problem but a glaring omission really and would be so simple to implement. ### 2/5 — サイクリングパワー設定 *2026-04-01* R-Q002Nを使っています。サイクリングパワーの計測がきつすぎて5分も続きません。ジュニアと判断されますが、初心者向けのトレーニングもきつすぎてもっと下げて欲しいです。本当にこの機種用のセッティングになってるのでしょうか？手動でもっと下げることはできませんか？ ### 3/5 — ネットワークエラーでログイン出来ません。 *2025-09-04* どうしたら良いですか。 ### 3/5 — Network error *2025-05-15, version 1.8.5* I love my bike and the app but sadly can’t use it due to Network error. I count on using the app and my bike due to knee issues. ### 3/5 — Customization *2024-09-22, version 1.8.2* It would be great to be able to make your own customizable workouts or select a workout that you can burn calories within a certain timeframe as a goal. ### 3/5 — Timing is all wrong *2024-09-02, version 1.8.2* For some reason the timing on my AI program is wrong, a 45mins workout i rode for 60 mins. ### 4/5 — Good app until it stops working *2024-08-17, version 1.8.2* update- server is back online, rating updated. for the last few day the app always gave "network error" and would not retrieve hiatorical records or current training progress. it gives me the feeling the main server is offline at Renpho head office. will update rating if this is fixed. ### 3/5 — Ai Gym *2024-08-14, version 1.8.2* Good app, have been using for several months but now gettin a network error message when I try to view weekly stats ### 2/5 — No option Apple Watch with iPad and no Peloton+ *2024-06-19, version 1.8.2* The manual states it connects Bluetooth Cadence with Peloton + , but it doesn’t work. Other apps will work with Cadence, but not Peloton+ as it states. Also, the AI Gym app on iPad does not comply with the iPad’s orientation, leaving the user to have to keep turning the iPad on the stand. How is that acceptable? Take a lesson from every other bike app (Zwift, Kinomap, Fulgaz etc). Please fix the orientation and allow the Apple Watch connect to the iPad. If Zwift and Peloton etc can do it, so can Renpho. ### 1/5 — Such a frustrating app *2024-02-03* Why do I have to spend an age downloading the same workouts, why can’t they remain on my device and/or be streamed without waiting for it to download, delaying my workout. Had a developer response saying they’ll remain on my device, but here I am waiting for the same workout to download yet again. THEY DONT’T REMAIN ON YOUR DEVICE!! Did a workout recently and rather than finish at the end, the workout kept going and failed to register. So annoying! Also, the ability to create my own custom workouts would be fantastic, but they need to get the app working properly first. **Developer response:** Dear customer, I appreciate your feedback and apologize for any inconvenience caused. If you have already downloaded the course on your device, the video will remain on your device unless you clear the cache or uninstall the app. Please ensure that your phone memory is sufficient. If you have any further queries, please do not hesitate to contact us at support@renpho.com. ### 1/5 — Updated firmware and app not reading bike data *2023-11-08, version 1.7.97* Since updating via the app , I can no longer use any of the app exercise programs!!! 😫 ### 2/5 — Nothing works since update *2023-11-07, version 1.7.97* Used to be a great app - I used the workout courses and tracking regularly. Nothing works since the update. I can get as far as selecting a course (or free cycle or anything else) and then it freezes on a grey screen. Disappointed. ### 2/5 — Cannot load user data after update to new version 5 days ago *2023-10-28, version 1.7.97* Too bad ### 3/5 — Bonne application ..Mais.. *2023-10-19* Bonne application Visiblement , le dernière mise à jour a fait disparaître la musique dans l’entraînement libre . Je l’appréciais vraiment car elle soutenait mon rythme . Que je clique sur le haut parleur ou non , c’est le silence absolu ! Dommage ! **Developer response:** Cher client, Nous vous présentons nos sincères excuses pour les désagréments causés. Nous résoudrons ce problème dès que possible dans la prochaine version. N'hésitez pas à nous contacter par courrier électronique (support@renpho.com)Cordialement, l'équipe du service clientèle ### 2/5 — Does not connect to Renpho bike *2023-10-17, version 1.7.94* I can connect to the bike with woohoo app, but not from AI Gym after the update. ### 1/5 — Network error *2023-09-16, version 1.7.94* Is the app down?? I’ve not been able to connect today…keep getting a network error message. I’ve logged out of my account and now I can’t get back in! ## Most critical reviews (10 lowest-rated) ### 1/5 — App broken since update *2026-07-03, version 1.8.8* UPDATE 3/7/26 App continues to go downhill, messaging support does nothing, utterly hopeless UPDATE 9/3/26 - this app gets worse and worse. I’m constantly having to re-download the video courses, and now the UI is all screwed since the recent iOS update where it only uses part of the screen when selecting a workout. Seems free truly means you get a 3rd rate product This app has always had a poor UI and is buggy, however now since the latest update it’s utterly broken. When doing an exercise, you get to the end of the routine but it remains at 0:00 and doesn’t complete, meaning you’re now unable to record your activity. Great job developers, broken an already poorly implemented app! ### 1/5 — App broken since update *2026-03-09, version 1.8.6* UPDATE 9/3/26 - this app gets worse and worse. I’m constantly having to re-download the video courses, and now the UI is all screwed since the recent iOS update where it only uses part of the screen when selecting a workout. Seems free truly means you get a 3rd rate product This app has always had a poor UI and is buggy, however now since the latest update it’s utterly broken.

Great job developers, broken an already poorly implemented app! ### 1/5 — Abstürze nach jedem Training *2025-11-17* Stürzt seit dem letzten Update nach jedem Training ab, Training wird nicht gespeichert. Damit unbrauchbar. ### 1/5 — must be online *2025-09-04, version 1.8.5* unfortunately, server is often offline. ### 1/5 — Horrible *2025-05-17, version 1.8.5* There are so many problems with this app that it negatively impacts exercise. The app randomly closes workouts. No point in using the built in workouts if it’s gonna close halfway through with no way to resume. Workouts tend to slow down the longer they run. The app hasn’t had a successful workout longer than 40 minutes. Garbage. Look somewhere else ### 1/5 — Network not available *2025-05-14, version 1.8.5* Network down nothing works in this app ### 1/5 — This still happen to disconnect *2025-03-29, version 1.8.5* That ruin your effort record and it just lose connection to the bike then bike reset to 10 resistance. This release of tension lose my balance and once I hit on the handle badly. No update correct this so I believe it’s hardware defect. And it’s mostly disconnect close the end of the goal. All time ruined. Useless app. ### 1/5 — App broken since update *2025-01-20, version 1.8.3* This app has always had a poor UI and is buggy, however now since the latest update it’s utterly broken. When doing an exercise, you get to the end of the routine but it remains at 0:00 and doesn’t complete, meaning you’re now unable to record your activity. Great job developers, broken an already poorly implemented app! ### 1/5 — Cannot open the apps *2024-11-26, version 1.8.2* Always said network problem but my network is totally fine, pls advice ### 1/5 — Netzwerkfehler *2024-10-17* Es werden keine Kurse, Videos oder Tests angezeigt. **Developer response:** Sehr geehrter Kunde, wir entschuldigen uns aufrichtig für etwaige Unannehmlichkeiten. Unser technisches Team hat dieses Problem umgehend behoben und es sollte nun normal funktionieren. Bitte melden Sie sich erneut bei der App an und zögern Sie nicht, uns zu kontaktieren, wenn weitere Probleme auftreten. Vielen Dank für Ihre Geduld und Ihr Verständnis. ## Most praised reviews (10 highest-rated) ### 5/5 — Great for free *2025-01-07, version 1.8.2* Used exclusively with Renpho underrated ai bike I’ve done over 530 miles using this app whilst watching YouTube videos and soccer, fed up with subscription fees on Zwift where I’m often zoomed past by bike doped egomaniacs. No Renpho has been the one for me to just tootle along or use the ftp builder. I use heart rate and the bikes power meter it can do hills up to about 6 or maybe 9 percent which I accept is no good for a very serious rider,but for most others I would recommend. Good app ### 5/5 — Audio issue *2024-07-06, version 1.8.2* The app reduces the audio played from other apps. This is frustrating as i like to listen to music on Spotify when I workout and the music is way too low. I’m an iOS developer and it’s a simple fix. It should only take priority if the user decides to listen to the in-app music. ### 5/5 — AI Gym *2024-05-19, version 1.8.2* Great app, perfect for Renpho AI Excersise Bikes. ### 5/5 — Works fine for me *2023-08-26, version 1.7.89* For the people having issues connecting APP to bike, turn on Location under phone settings and make sure Bluetooth is enabled. Enjoy ### 5/5 — It works great *2023-01-13, version 1.7.78* I set up my goal and track every day, working great so far ### 5/5 — Success *2022-08-25, version 1.7.70* The product, as it is, works well. Thank you ### 5/5 — Works well *2022-06-17, version 1.7.67* Works great for the bike and the app is completely free. ### 5/5 — Why the Video didn’t show up once complete downloaded. Try many times *2022-05-20, version 1.7.66* Why the Video didn’t show up once complete downloaded. Try many times ### 5/5 — Update - reset Bluetooth after firmware update *2022-04-18, version 1.7.63* I sent a review after my AI Gym stopped working after a firmware update. Renpho answered the call within a day or two with instructions on how to reset my connection and get things going again- together with a direct email if this didn’t do the trick. It did, and I’m delighted to be reconnected on my Renpho bike with AI Gym on my iPad. Thanks, Renpho! ### 5/5 — Great app, thanks! 👏 *2022-04-05, version 1.7.63* Really great app, thanks! The free app was a good reason to me to buy the bike. It works well. Great job. Continue! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
