I can’t log in because I can’t find my username, so I just give up and do something else. Just make it email or username. On the positive side 20 free workouts is a great way to get users into it. The app works well. ### 5/5 — Awesome *2026-01-05* This app was very quick to get setup. I installed the watch app and instantly got heart rate info (something Zwift can’t or won’t do for $20/mo). It instantly saw my Kickr and I was off riding in less than 5 minutes. When I was done all of my data was in Apple Fitness. It’s exactly what I wanted. ### 5/5 — Better than Zwift *2026-01-04, version 8.5.3* I rarely leave reviews, but I genuinely love this software. I was a Zwift user back when it first launched, but over time the cost became hard to justify—especially without meaningful updates to match the price increases. I also found myself watching YouTube or TV instead of engaging with the Zwift screen, which kind of defeats the purpose. That’s what led me to TrainerDay. It delivers exactly what I need without the fluff or extra cost. The app is simple, clean, and just works. Huge thanks to the TrainerDay team—you’ve got a fan! ### 4/5 — Very frustrating *2025-12-23* I normally don’t leave bad reviews but i purchased the upgrade and I’m still locked out of the premium features. Also, I don’t see any way to contact the app developers for help. Update: I unsubscribed using apple and resubscribed in the webapp and it seems to work now **Developer response:** Very sorry here, I don't get these notifications and so I don't see this and I don't log in here every day. I hope you got it fixed. ### 5/5 — Great for the price. *2025-12-16, version 8.5.0* I don’t need a video game. Just workouts. This is it for the money. ### 5/5 — Perfect *2025-12-14* I was a previous user of a similar more expense product, but I am not that serious. This is a great app. Does everything I need for structured workouts. ### 5/5 — Game-changer for Heart-Rate–Based Training *2025-11-15, version 8.4.2* I started with TrainerRoad but found the workouts way too intense for what I needed. I switched to heart-rate training with TrainerDay and it has been an amazing experience. The app makes it incredibly easy to structure Zone 2 sessions, add some tempo when I want, and keep my heart rate from going off the rails. The workouts feel sustainable, effective, and perfectly aligned with my long-term goals. TrainerDay has completely transformed how I train. Simple, flexible, and exactly what endurance athletes need. Could not recommend it enough! ### 3/5 — Ramp Test *2025-10-14, version 7.7.6* On the first part of the test, the resistance on the trainer didn’t seem to follow the ramp profile. Then I fiddled with my settings & it went to immediate full resistance. So I stopped it & started another workout session which seemed to follow fine. Hopefully just teething problems for me. ### 3/5 — Tacx Bushido Bluetooth Pairing *2025-09-09, version 6.9.7* Worked fine in previous versions. Resetting reinstalling and trying to pair again fails every time. ### 5/5 — 최고의앱 *2025-09-06* 이 앱을 알았다면 트레이너로드를 쓰지 않았을것이다. **Developer response:** Thank you!!! ### 5/5 — No thrills, just perfect app *2025-09-05, version 6.9.1* Affordable and brilliant. Does the job and ai coach jack is brilliant… Good app with regular support, what’s not to like. ### 4/5 — App crashes often *2025-08-25* Update: the developers are quick with a response and a fix. I have updated my original rating and app works as expected App will crash mid ride or before saving. Based on the online forums this seems to be a common issue. While it was working, it was great. A good value compared to other smart trainer apps. **Developer response:** Sorry about that. We accidentally had a beta version go to production. Version 5.4.4. The new version should be resolved. ### 5/5 — So much love *2025-08-20, version 5.4.4* Best for structured cardio. Dev/founder is super friendly and responsive. Incredible useful, elegant features. ### 3/5 — Amazing app marred by lack of data sync *2025-04-30* The app is amazing. You can do enough for free that most wouldnt need to pay for more, and the ux is better than some other apps I've tested. Plus, an apple watch app too! My big problem is that the app does not sync Power or Cadence data from sensors into apple workouts. I like to track that kinda thing and it's imperative the app I choose does that. It's apparently been on the road map for multiple years now, but I hope to see it soon so I can come back to this app and support them (and please retroactively sync that data when it's finally able to) **Developer response:** Sorry for the slow response. We actually are going to start working on this. ### 5/5 — The best value training app available *2025-02-27* I stopped racing competitively as a cat 2 on the road 10 years ago. Last fall I decided to get a smart trainer and see if I could get some of that fitness back - and I did! I went from 2.8 ftp to a 3.9 ftp in 4 months using trainer jack’s base and sweet spot plans. The workouts are great to get a basic (but effective) structure around your training. Highly recommended due to its high value. ### 5/5 — Affordable and easy to use. *2025-02-18* Not quite the same as TR but you get 75% of the features for 25% of the cost. I just wish this was available on Apple TV. ### 5/5 — Incredible app and incredible developer *2025-02-14* This app is perfect for controlling your indoor trainer and even can pull your heart rate from Apple Watch for free. On top of that the paid options seem really reasonable and the developer is pretty responsive if you have questions. ### 5/5 — Test2 *2025-02-03, version 5.1.5* Great ## Most critical reviews (10 lowest-rated) ### 1/5 — Кошмар *2026-04-02, version 9.6.5* Приложение постоянно сворачивается, этим просто невозможно пользоваться ### 1/5 — Constant Crashes *2025-02-11, version 5.1.7* Used to be a great app, and still works great until you need to save an activity. Upon clicking Save on the Workout Finished screen, the app crashes and returns to your Home Screen. ### 1/5 — Ux poor, hard to find anything. *2024-11-11, version 5.0.7* Focus on training info and aim otherwise you loose track of your user ### 1/5 — Crashes constantly *2024-11-05, version 5.0.7* Paid for the subscription and the app crashes every time I use it. Worse than useless because it’s frustrating as heck. ### 1/5 — Just crashes *2024-05-28, version 4.8.2* Can’t end my first workout. Multiple crashes during the workout. It also crashes every time I hit stop. One time I made it all the way to save but still crashes before saving. I was hoping for a zwift alternative but this isn’t it. ### 1/5 — Poor *2023-11-13, version 4.2.2* Set up and calibrated my Kickr Core. Pairing devices was straightforward. First ramp test ended early with no ramp. Second attempt ramped up so quickly I couldn’t get through half of it. Waste of time. ### 1/5 — HR does not work. *2023-09-17, version 3.9.0* Tried everything. It was like being tortured. ### 2/5 — 파워가 일정하지 않고 자꾸 튑니다. *2024-10-22* 무료라그런지 이부분은 해결이 안되는군요. 아쉽습니다. ### 2/5 — Potential but where are the features and devs ? *2023-10-16, version 4.1.7* Has potential but it’s missing important features. At its current state it’s not worth the $. I’d rather pay more and have more features. ### 2/5 — Not connecting to kinetic trainer and no ability to change weight on the app *2021-12-18, version 2.6.2* To my kinetic trainer ## Most praised reviews (10 highest-rated) ### 5/5 — Tacx + Apple Watch *2026-07-07* I finally got this app to connect with my second hand TACX trainer and Apple Watch for a heart rate. It appears not many apps do that. If you’re having trouble, connecting your Apple Watch heart rate data to the app make sure to open the Trainerday app on your Apple Watch, also allow heart rate monitoring in settings under privacy and the Trainerday app. ### 5/5 — Does what it’s meant to do, no fluff *2026-06-17, version 10.0.3* If you don’t care about the VR part of cycling and just want to get good reps in. This is the app for a fraction of the price. ### 5/5 — Amazing *2026-06-16* the app and its functionality amazing! But it is second compared to Alex and his team. What they do behind the scenes has saved me from needing to buy a new trainer. Thank you Alex! ### 5/5 — Great option for training *2026-06-03* I got this app because I was supplementing my strength training and running routine with indoor training, to also be in shape for some casual mountain biking, and got tired of paying for features I didn't need with TrainerRoad. Found this app and I'm blown away. I can't tell much of a difference and like the ai workout generation better than TrainrRoad's. Wish I'd found it sooner. Nicely done, TrainerDay team. ### 5/5 — Great app *2026-05-13, version 9.9.7* Been using for 2 years. Helped me train for numerous events. Great workouts and pricing. Give it a go, you won’t be disappointed. ### 5/5 — Is App… is good! *2026-05-12, version 9.9.7* Nice app at a reasonable price. ### 5/5 — Best affordable ERG app *2026-05-11, version 9.9.7* Been using this app for years to run my TrainingPeaks workouts. Easy to use with all the right features, at a fraction of the cost of Zwift, TrainerRoad, Rouvy, etc. ### 5/5 — Perfect training app *2026-04-10, version 9.6.8* Simple, smooth and just works. Switched from training peaks premium to trainer day and it’s a better app at half the price ### 5/5 — Impressed *2026-03-16, version 9.1.3* Coming from Trainer Road this is a fantastic and similar alternative and for me (grandfather pricing) a third of the price! Having to manually upload to Garmin is a pain but doesn’t take long. Make sure you sign up via the website it’s cheaper. ### 5/5 — Relative simplicity *2026-01-30* I tried the apps that have gaming and videos and I find the very distracting even though they are quite impressive in appearance and functionality. Trainer day is perfect for me. It is simple, straightforward and very pleasant to look at even though it is static relative to the others. Rich in workouts and plans, smart management of both within the app itself and those it connects with. Perfect for me. Well done. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
