I like the idea, and watched videos on the mfg website, but after installing the app on my iphone 5s (with latest updates), it loads the login screen and immediately freezes. I cannot enter any login information or interact with anything in the UI. I tried restarting my phone and even re-installing the app to no avail. Went with BitGym instead.
