Definitely a fan of the metrics you’ve shown here. Great to see how you experimented along the journey and didn’t give up. I’ve seen many indie devs assume that their apps will be a great success when released, and then when it’s not give up due to disappointment.
Your write up has been really useful for us as we experiment with marketing our app (Color Crunch) before its release.
Heres the promo video of our app if you’d like to take a look: http://youtu.be/VPArA7eT22E
