Ask HN: Transition from Free to Paid Apps - Android

Hi All,

Are there any good/established/proven strategies on how to transit from a free app to paid app on Android Play Store?

I released my first app on Play Store, and I have been getting some decent downloads in last couple of days. I understand that this could be entirely due to the fact that the app is free. I wonder how does someone go about on this decision to make a paid version of the app, with some added features.

I am not sure if I can share the link here on HN (guidelines), but I will be happy to share if it is acceptable.

Thanks!
