After blindly going about mobile app development for the longest time. I recently learned/experimented with a few simple things, that I'm embarrassed that I avoided for so long & I know there's more things to explore with A/B testing.
I made an Android app called "Delightful" (also now on iOS - http://delightful.today/), a simple gratitude journal & gradually got downloads over the last few years & app reviews. I've earned about $30 so far from in-app donations (which I know is not sustainable).
The things I finally started experimenting with are Play Store A/B testing on my app's description & adding code for rating popups in the app.
I added a simple rating library to my Android app at the beginning of June, that pops up after starting the app 10 times or opening it after 14 days. I had about 20 app reviews & now after 2 months I'm up to 104 reviews with a 4.8/5 rating.
The tools available by Google are awesome to test different versions of your Play Store listings. On the flip side, it seems difficult to optimize your Apple App Store listing without multiple app updates since I learned that Apple doesn't let you change your listing without an app update. So I plan to use my Play Store app description for the Apple App Store & see if that translates to more downloads there too.
For anybody making mobile apps, any advice on ASO & optimizing apps on multiple platforms? Any other mobile app advice?
