Not sure why they didn’t just update the previous app, but ok. The new app has some new additions that are nice. Gym card now is available in the Apple Wallet, however, because it isn’t NFC and instead is a barcode to scan, it doesn’t show the barcode on the Apple Watch Wallet - preventing you from being able to leave your phone at home and only using the Apple Watch. It takes a long time to prep your workouts and you aren’t able to prep the reps you plan to do prior to the workout. You have to start the workout before you can record your reps. I have a schedule that I would be willing to transfer to their app but because there isn’t an import feature, it takes a long time to do, and you can’t prepare your workouts prior, it makes it completely useless to me. I don’t ever open the app now because of the lack of these features.
