Its really hard to get attention from the app stores themselves until you've been on there a while and have good ratings and user history. The exception to this is that you go viral, which is unlikely of course. You want to think about distribution early on the same way you would a web app. Get it out there on all the standard GTM channels and get those early downloads. The rating is probably the most important thing. If you don't actively pursue positive ratings then the only ones you will get are bad ones from upset users. My advice is to deploy, develop a strategy day 1 for getting positive app store reviews, and then of course play around with paid ads if you have a subscription based app you can monetize and get a positive ROAS on.

So cool to hear that, tell her I said thanks for using Pangobooks!

It looks really good. I did have trouble figuring out what it was though. Maybe the hero title could be more specific?
