The solution to using multiple apps during your workout is here, and it's called Pedal! A hub for all your data, with a focus on cycling.
In april 2021 I started cycling, and quickly realized that I wanted a way to track my rides, my weight and my progress. There wasn't any app out there that could do all those things at once, so I decided to make one myself.
I started designing a few mock-ups. And after a few weeks of development, I had a working prototype. I used NextJS for the app and Firestore for the database. I then started working on automating the import of ride data from third party apps and I'm currently still working on integrating with more apps.
Examples of how the overview, profile and ride badges look like are shown here. The ride badges also feature achievements and tiered styles ranging from bronze to platinum.
