First, check out how the old design looks like:

This is how my redesign looks like:

In Redesign, I added features such as:

1.Hinting all the related apps on the splash

2.Faster switching between children's data

3.Separate errors for each field in the login form

4.Second parent registration, while would increase the app installations with at least 25%

5.Children's activities capturing and sharing(which would share the app itself)

and more...

Have fun!
