App works OK when it's needed. The UI could use improvements for sure. The latest update has an updated sign-in page. The"remember me" checkbox turns white with a very faint checkmark, to signify it's going to remember your username. That needs to be changed. Settings are buried deep in the app under "My Chart" and not an easier-to-find location. Really hate having to sign in every 2 minutes... Or at all on my password protected phone.
