On an aesthetics note: pick a cleaner, more serious font than the script. It shows that you mean business with your app and it's meant to be used seriously rather than as a fun one-off.

On a consistency note: the examples in your copy should match those in your example image. You have 30 min for exercise and 1 hour for emails in the image but they're the opposite in your copy.

The app looks good though and quite useful. Might I also suggest, instead of listing all the features to have them displayed around the image with arrows pointing to what they're referring to. Context can make all the difference, especially with a long page.
