HealthFit

The app was very easy to set up: A couple minutes after download to configure what data I wanted sync’d, and I was off and swimming/running. I actually spent most of my time remembering my logins for the data syncs like Strava, SmashRun, and Dropbox. :-) For me, the key feature this app enabled was pulling activity data off my AppleWatch+iPhone into a storage sync of my choice. Without it, I had to get multiple activity apps for the variety of workouts I do (e.g., Strava doesn’t track swimming). HealthFit simplifies things for me in the background, with very prompt synchronizations (feels like seconds between when I wake up my phone, to when I get notified of sync completion). When the start time of my activities uploaded to Strava didn’t look right, and I reached out to support, Stèphane was very responsive and helpful in chasing down the cause, which turned to be Strava not using time zone information. Stèphane even went out of her way to share potential solutions Strava-side. This demonstrated the developer’s dedication and passion for the success of this app!

Edited after developer's comment: This is NOT how CTL works. Yes, CTL is the 42 day training load. ATL is the one week training load. Agreed. But go to any search engine you want, ask any AI you want, talk to any professional trainer you want,,,CTL will not go from 120 to 44 during a 3 week rest period. Most will tell you it should drop slightly over 10%. You DO NOT loot a year's fitness in three weeks. If you believe that, you do not understand the CTL/ATL/TSB model. Have a food day. This app is both great and terrible. It's great because it gathers all of the data your watch collects during each workout and presents it in a clear and easily understandable manner. If all you care about after your workouts is time, distance, pace, heart rate, and these types of basics, this is the app for you. BUT, they claim to give you accurate fitness (CTL), fatigue (ATL), & form (TSB) data, which in my opinion they DO NOT. I started the year with a CTL of 44. I ran through the spring and moved to my bike in the summer and took my CTL up to 120. I then took three weeks off as i transitioned back to running. In that three weeks off, they dropped my CTL all the way back down to 43! Running outdoors in November brought it back to 67. That was last Sunday. This week i did 5 treadmill runs: 1 in HR upper zone 2 and 4 in mid-zone 3. I took Wednesday and today, Sunday, as rest days. Today's CTL is 64, three points lower than last Sunday. At this rate if i run all winter i'll get my CTL back down to 44 again and show ZERO fitness gain from 430 miles run and 1,240 miles on my bike. Nonsense. Bogus. Laughable.

wow. healthfit (HF) is special. if you want to centralize your workout data (some of the most personal and valuable information we record) for your own analysis or to simply possess that information, you need to get HF. the value is incredible. my use case: I wanted to see how certain metrics have changed from my 20s to now (40s). over those 15ish years of recording, I've used different platforms: mapmy, runkeeper, strava, apple health, coros, whoop, and trainingpeaks. turns out that's a much harder task than I imagined. the earliest data is just gone: mapmy apparently deletes inactive account data. runkeeper either has the same practice or deleted my info when they were acquired by shoe brand. the rest of my data was divided between strava, apple health, coros, and whoop platforms. besides coros, none of the others exported usable data. enter HF. this team has put together an incredibly powerful tool that "just works" for an incredibly reasonable price. no subscription, data is only yours and is stored locally, and you can export data to various formats and file types. plus it offers you a private analysis and planning platform. the only thing I wish is that all the connections were two way so that users can push and pull historical data from anywhere. currently it appears HF can only pull historical data from apple health. that said, the team is probably limited by those platform's APIs. BUY IT!
