This app is very straightforward, just a series of screens with on-touch audio, and a tracker at the end, so users can be inspired to use it every day. We have the design! There is a storyboard so you can see all of Day 1 at a glance. This storyboard refers to Day 1, and there are 6 more, almost-identical screens, so only the .mp3 and .jpg / .png name needs to be swapped out.
After the user completes Day 1, logs back in, Day 2 appears, then one by one Days 3-7. On Day 8, it goes back to Day 1 and then just endlessly loops from there.
