First page on app launch is for account creation / sign-up. That's my pet peeve. Let the user experience the app first, before asking them to create an account. Moreover, a task manager should NOT have a mandatory account requirement to begin with.
EDIT: No, I did not get a chance to use the app functionality, as the very first screen was "must create account". Since I didn't have an account and didn't want to create one without seeing the app functionality, I uninstalled the app after the first screen itself.
