For a while I have been looking for a good self-hosted solution for recording my gym sessions. I have a good solution for tracking my cardio sessions (cycling and running mainly) in Endurain, but never for strength training. I have tried a few:

• wger - a good solution, but the UI is a bit dated and it is also geared towards managing a gym rather than a single user.
• Wingfit - also good, but I just did not click with it. Shame, because the developer is from Brittany, which is my adopted home.
• A multitude of different open source Android apps. These all had UX issues and no syncing, so kind of sucked for me.

As a result, I stayed on Strong for much longer than I would have liked.
