Monetizing Apps

I’ve been thinking about models for making a little money from my iOS apps. I only have two at the moment and they’re both free on the App Store. Neither app has been downloaded in large quantities. [RxCalc]( – a pharmacokinetics calculator – has around 10,000 users and [Arrgly]( has a super tiny user base – I built it for myself and decided to share it. And, yes, I know the name and UI are completely goofy.

I’ve been working on a new application called _Stream_ and I’ve gone round and round in my head about monetizing it; should it be FREE, free with in app purchase, free with tip jar, or up pay once up front?

So many choices.

My initial thought was FREE with an In-App Purchase Tip Jar. This would allow me to, hopefully, make a few bucks from it and I could reward users with additional icon sets and color schemes.

Then I happened across [Ko-fi]( It looks like a nice way to make a few bucks off of my hard work and not give Apple 30%. On the flip side I wonder how much I’ll lose because folks have to visit my site to tap on the Ko-fi button to support my apps.

If anyone reads this, and knows a little about Ko-fi, could you let me know if it’s something I could, or should, use to support my apps?

Just send email to
