We initially built the tool for this app:
https://itunes.apple.com/us/app/7-second-meditation-daily/id...
From hundreds of different daily meditations it has learned precisely which order to show the content in to maximize retention. So it knows the best message for day 1, day 2, day 3, etc.
The first month retention for this app is 43%, up from the 20s before optimization. The current rating is solid 5 stars ands usually in the top 10 in the mindfulness category.
The In App Purchase prices are automatically optimized, and soon we'll be throwing in a bunch of different background images, all of which will be automatically optimized.
Anyway, I really appreciate the feedback.
