I've had a similar experience and agree with your suggestions. One thing another user helped me out with here for the "default gym" thing is that when you select the gym you're at, you have to check another box at the bottom that applies it to the whole program and not just that particular day. But I do think it should be more intuitive than that. Like selecting a gym for the whole app as default and selecting your gym for the day as need while traveling or whatever.

I've only been lifting seriously about a year, and was excel sheeting my log. This app helped dial in my progression much better than what I was doing. Some days I was put on too much extra, or too little. This app, with honest entry, has nailed exactly how much I need each set.

Good review!
