Had one where it recorded a partial workout. **Developer response:** make sure you have the latest version of the app installed. For any problems, please contact us at support@selfloops.com ### 2/5 — Concept2 rowing *2020-03-17* UPDATE Mar.22.2020 Watch stopped syncing after about 2 Weeks of using the app! WISHLIST - Mar.07.2020 The trial version does not allow syncing with third party apps - so I have no idea how this functionality works (for concept2 dashboard). It would be nice to give it a full testrun before deciding which app to purchase (as I am assessing several). That said, the reporting and presentation of stats after a rowing session are very good. UPDATE SelfLoops support very responsive - and the issue I originally reported was resolved in a few days. Feb 2020 : BUG - when iPhone set to dark mode - there is still a white background with white text. So you cannot read the text. However, this is better attempt than concept2 at integrating the Apple watch with the world's most popular rowing machine. **Developer response:** Dark mode support is now available, just update the app. ### 2/5 — Does not work with my Apple Watch *2020-02-26* I have downloaded this app many times. Unfortunately I have yet to get it to work on my watch. Customer service has been trying to help but all through email. I would like to talk to someone on the phone that can lead me to fixing this problem. **Developer response:** Please contact us by email and provide your tel number and we'll provide all the support you need to get started. Thanks. ### 1/5 — What the ??? *2020-02-06* It auto generated my gender, my weight and how I view the units, and there’s no where for me to fix this. So, renders the app totally useless for me **Developer response:** It is now possible to edit all your settings within the app. Please, update the app to the latest version. Thanks. ### 1/5 — Will not open *2019-08-03* I’m struggling to get the app to open on my Apple Watch. I’be added and deleted it multiple times. Any ideas for a fix? **Developer response:** please update the app to the latest version. If you have problems, please contact us by email. ### 1/5 — App does not open on watch *2019-01-17* Installed and setup to watch. Logged in and verified from phone. Click on icon on watch and nothing happens. If I can get it to work with my concept 2 rower I will change the rating but for now it is not working at all **Developer response:** Hi Philbert, could you please write to us at info(at)selfloops.com We would like to learn more about your problem. If there is a problem, we'll fix it. You can also try to update the app to the latest version. Thanks. ### 1/5 — No se instala en el Apple Watch *2017-10-17* Aparte de no instalarse en el Apple Watch tampoco funciona en el iPhone, se cierra. ## Most critical reviews (10 lowest-rated) ### 1/5 — Pessimo *2025-02-07* Su Apple Watch funziona malissimo: dopo aver lanciato l’allenamento ci vogliono almeno 5/10 minuti perché inizi a rilevare il battito e le calorie. Durante l’utilizzo spesso si blocca per periodi di almeno 2-3 minuti. In definitiva i dati che rileva non sono affidabili ### 1/5 — Bad app. *2021-07-20* Bad app. Can’t keep connection, lose data ### 1/5 — Not very well programmed *2020-12-16* Downloaded the app on my Apple Watch to sync it with my Concept 2 rowing machine. But the support is really buggy. It only registers one training interval more than one are not captured by the Watch. And if you press menu on the erg before you end the workout on the watch, it doesn‘t get saved at all. Nice try but that way I cant recommend it **Developer response:** The app currently does not support intervals. ### 1/5 — Very clunky and difficult to properly evaluate *2020-11-09, version 4.5* I found this quite difficult to install and set up - so much so that I gave up the first time I tried it and deleted the app from my phone. I’ve since had another try, but now that my trial subscription has expired and I’m not prepared to fork out €49 to see if it will do what I want it to in the Premium version, that door is now closed to me. What I can report is that I can’t ‘see’ the PM5 from the App running on my phone (SE 2nd Gen, iOS 14) but it syncs straight away if I initiate it from my Apple Watch (series 3). The workout records and syncs to Apple Health, and buried deep is the distance, except that it doesn’t seem to be accessible to HealthFit - I don’t know why but I suspect it’s been written to the wrong place internally. I’m going to go back to using ErgData instead, and will probably just fork out for an independent HR monitor. Sad.... ### 1/5 — Déception *2020-05-24* App marche parfaitement mais on ne peut enregistrer les sessions grâce à l’Apple watch uniquement si iPhone à proximité. **Developer response:** L'iPhone n'est pas à proximité pour utiliser l'application Apple Watch. Si vous rencontrez des problèmes, veuillez nous contacter à support@selfloops.com ### 1/5 — Is this a con?! *2020-05-16, version 3.3* I seem to have automatically been entered into a subscription after a free trial. Which I can’t afford as a student. No option to cancel subscription, no way of contacting to cancel, as contact form doesn’t recognise my login details. ### 1/5 — Ne fonctionne pas sur Apple Watch 4 *2020-05-11* L’appli s’ouvre (ou semble s’ouvrir) et se referme immédiatement. Dommage, c’était prometteur sur le papier... **Developer response:** assurez-vous que la dernière version de l'application est installée. Si vous rencontrez des problèmes, veuillez nous contacter à support@selfloops.com ### 1/5 — Doesn’t work *2020-03-01* Paid for premium to connect to my Concept2 rower and it says its connecting but it doesn’t transfer any of the data over. Completely useless! Updated 1st March 2020: Stand by the fact that the app didn’t work even when paying for premium. Developer did send refund after brief email back and forth discussing the issues. **Developer response:** Several people use it everyday to connect to Concept2 machines (rowers,skiErg, bikeErg). This is the only Apple Watch app able to connect to C2 machines. We'll always provide full refund, no questions asked. ### 1/5 — Crashed when trying to input age *2020-02-21* Downloaded, tried to change some settings and it immediately crashed. In dark mode, the settings panel has white text on a white backdrop. Not ready for prime time. **Developer response:** Please contact us by email and we'll provide all the support you need to get started. Thanks. ### 1/5 — Doesn’t save data *2020-02-07* Weight wrong, MHR wrong, no way to input correct numbers and didn’t save data after a PB on my erg. Deleting as my AW does a better job on heart rate. **Developer response:** It is now possible to edit all your settings within the app. Please, update the app to the latest version. Thanks. ## Most praised reviews (10 highest-rated) ### 5/5 — Works great! *2021-10-22* Connected to my Concept2 ERG, recorded all data, and synced with Apple Health on the first attempt. Using Apple Watch Series 7. Awesome! ### 5/5 — Great App *2020-07-02, version 3.5* As a concept 2 user (Ergo) I was incredibly disappointed to see that neither the native app nor the ergo itself supported Apple Watch connections. This app has bridged the gap. Initially it had problems with remembering calorie data when disconnected from the machine before ending the workout. This seems to have been fixed and the app works great. Would highly recommend, well done developer! 👍 ### 5/5 — use it at my local gym *2020-03-06* I love it!!! I just walk in to my gym and tap the spark icon on my apple watch and my name is up on the heart rate monitor for my workout! And it fills in my rings cause I am a freak about closing them!! **Developer response:** thank you ### 5/5 — Apple Watch for Group Fitness Classes *2020-03-06* Selfloops is outstanding! Spark is the only app that lets you connect your Apple Watch as a heart rate monitor for group fitness classes on the big screen, and uploads all your workouts to the Selfloops dashboard for analysis. I have trained for 50k paddle board and trail running races with Selfloops as well as all my day-to-day fitness over the last 4 years and adding Apple Watch support was a great (and convenient) addition! ### 5/5 — App for Apple Watch not found *2019-10-08* Downloaded the iPhone app, but the Apple Watch app didn’t appear. I emailed Selfloops and they got back to me fast with correct troubleshooting steps. Now it works great and I’m syncing my Concept2 data with my Apple Watch! So awesome. **Developer response:** Thank you! ### 5/5 — Works well *2019-07-19* It took me a little trial and error to get it connected to my concept to rower, but once I did it worked perfectly. Connects to my Health app, and monitors my rows. **Developer response:** Thank you! ### 4/5 — Issues *2020-05-07, version 3.3* Problem 1: when recover my data, even it is rowing, it will show as cardio. Problem 2: when I refresh my activities, duplicate items will appear. ### 3/5 — Issue with syncing the whole workout *2020-08-29* It will not sync for longer than 45 mins for a group workout session. It will end the session and then start a new session. It will track the new session on my watch & phone but now on the workout screen at the gym so I cannot easily very my HR **Developer response:** there are no limits of 45 minutes for a session. Please make sure you have the latest version of the app. If you still have problems, please contact us at support@selfloops.com ### 3/5 — Need iOS12 version *2018-09-18* Pairs nicely with concept2 rower. However, stops pairing once I updated to iOS12. **Developer response:** A new version is available on the App store with full iOS12 and WatcyOS 5 support ### 2/5 — Not working after update *2025-07-28* The app will not work in the gym after the update. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
