ABI Research has a new survey that found that 3% of users account for one-fifth of all money spent on mobile apps. What does this mean for mobile developers?
Firstly it probably means you need to make the most of the 3% of users who will pay. This means cross promoting your other apps to them, offering them extra in-app purchases and related (web side) services.
The press release doesn’t say why the 3% chose to pay. If you can discover this, for your particular app, maybe you can concentrate on this aspect (technically or marketing-wise) to get more paid users. Support and talk to your paid users and get some insights into their motivations. Many paid users want you to succeed so they get continuation and upgrades to the app. My experience is that most will be open to helping you.
