I'm surprised that none of the mobile apps I tried will send me a notification prompting me to enter data. Instead I have to remember it myself, open the app, navigate through a few screens and finally enter a single data point. Ugh.
Instead I should be prompted to enter the data via a notification, and when I tap the notification the app should go to exactly the right place to enter the data. It should be: a notification pops up, tap notification, enter data, save. That's it.
