Ask HN: What iOS app pricing strategy worked for you?

I did public transport train routing and scheduling app for my city.

Free + iAP worked for me, with around 4% conversion rate. Granted that the iAP is priced at just $0.99, most feature are free, just that viewing the train ticket price and which stations are near to certain attraction places require iAP

It really depends on the type of app you’re offering and your user acquisition costs/strategy.

Freemium games with in-app purchases and ads worked for me but I’m sure paid apps in top categories can do amazingly well.

I recommend you do some research in sensor tower to get an idea of the landscape.
