I tried to use it but I found the UI/UX confusing, with many exercises lacking images too. I support the idea but the workflow was not for me.
I settled with Iron for iOS, which is also free software despite the platform it runs. Still looking for an equivalent on Android, the LiftLog app seems to have potential, but I think the UI is not that great.
I've been lifting for ten years thereabouts. Used JEFIT, Hevy, and Strong throughout that time.
I've given up on apps completely and log with a reMarkable.
All of these apps use their own data schemas, which makes normalizing the data for export into something like Google Sheets really hard. Consequently, you're locked into those apps and whatever design choices they choose to implement.
Moreover, I don't like using my phone when I'm at the gym, and, well, they're phone apps.
