I would love to give this a higher rating as it's very useful for having easy access to my medical information and such, but it's incredibly frustrating that I regularly have to uninstall and reinstall the app because it won't open if I forget to sign out before I close the app. When I first downloaded it a year or so ago, it did just fine with opening and then using my swipe passcode to 'log back in'. Then a few months later it began having issues, and I can't figure out how to fix it.
