I made 22 sales total of Safe Vision app on Amazon App Store between July 12 and September 12, 2017. After that I changed the app to require paid subscription of $15 per year with free 7 day trial. I also offer free 1-year subscription if parent helps the project with classifying videos: safe.vision/free

So far nobody purchased the subscription and one person received free 1-year subscription (someone from Poland).

I decided to start tracking key metrics for my business: acquisition, activation and retention. I’m going to track them based on weekly age cohort (click for bigger image):

The chart shows that for example in the week starting September 18:

• 90 people installed the app (acquisitions)
• out of those people 23 watched at least 10 videos on the same day or the next day (activations)
• 11 people watched at least 5 videos a day after installing the app (retention)

My plan moving forward is to start inbound marketing by making guest blog posts. Please let me know if you have ideas on topics that would be interesting for parents of kids 5-7 years old.

Also I’m going to ask parents that installed the app recently to give me feedback on why they decided not to use it.

Onward!
