I have developed a Powermeter Comparison app for iPhone and iPad, that allows users to simultaneously connect and analyse up to 5 power sources.
Typical use case would be to compare in real time a smart trainer against an onboard powermeter and, in some cases, two powermeters (crank + pedals for instance).
The app will also output a CSV file with all sources perfectly synced or up to 5x fit files for upload to analysis software, again perfectly time synced.
I understand this has niche appeal to bike geeks/nerds but having been a Slowtwitch forum (mostly) lurker for over 20 years I know this place is the natural habitat for data obsessives.
The app has been in testing with a select group for a couple of months and I believe it is close to final release but i’d love to widen the testing team so if you have an Apple Testflight account and are interested, drop me a PM with your testflight email and i’ll send you an invite.
I plan to charge a small annual fee (under $10) for the app but will provide a lifetime code to testers who are happy to provide a minimal amount of constructive feedback.
Any questions, even if you are not interested in testing, fire away!
Looks like a nice app and could be useful. But there are a few optin for comparing power meters already around. Such as: Zwiftpower, Trainingpeaks dualrecording, DCR Analyzer
Thanks Ben, and agreed that options do exist for power file comparison. Zwiftpower and DCR Analyzer are both for post ride analysis though and have the challenge of time syncing separately recorded files from different head units. I believe TrainingPeaksVirtual is the only one that has live dual recording functionality?
Cool app. Unfortunately I’m on Android, so will have to wait until someone might come out with similar for that OS.
I’ve been using a ConnectIQ app that allows for dual recording quite a bit, but unfortunately it doesn’t work on newer Garmins. I haven’t understood why none of the head unit manufacturers has implemented the option yet, but maybe it comes down to trying to avoid the basic fact that it would show discrepancies that many of them are probably not interested in casting light on as they are themselves manufacturers of powermeters.
