Hi, I’m Reinder. I help people play with code.

Play with code? Yes! I built LearnAppMaking.com to help iOS developers make their best apps – for fun and profit.

Maybe you’ve come up with a great app idea, but you’re new to iOS development. Maybe you’re thinking about a career change and want to learn how to get hired as a professional iOS developer. Maybe you’re looking to make money in the App Store, and you want to know how.

I’ve been there. I had the ideas, wrote the code, made the deals, and conquered the bugs. It took me years to figure out how all that stuff works. I mean, I once showed up at a company meeting in shorts!?

I finally got to a good place where I can create my best work. I want to help you do the same.

The Story Of How I Got Here

I’ve been a professional software engineer since 2007. In 2010 I built my professional first app – a barcode scanner – for about $400. I told the client it would take me one day of work. Or so I thought…

Invoice no. 15

I had no idea how to build apps, so I bought a book: Sams Teach Yourself iPhone Application Development in 24 Hours. The original – now useless – first edition! You’d code Objective-C of course, and iOS was still called “iPhone OS 3” back then.

I soon learned that “24 hours” was a bit of an understatement. I finished the app about 3 weeks later. It was then that I decided: I want to build iPhone apps (and preferably for more than $5/hour).

Since then I’ve created a few dozen professional apps for iOS, Android and the web. I’ve worked for local startups, global brands like Philips and Tommy Hilfiger, and created indie apps of my own. My code, designs, articles and tutorials touch the lives of hundreds of thousands of people around the globe.

Some of my more “professional” accolades include:

  • I once made national Dutch television with a website to raise awareness of violence in public transportation – although I had faked the “votes” on the site
  • My MacBook broke down on a tropical island and I had a client deadline 3 hours away, with no repair shop in sight – got it done with screen mirroring on my iPad and got the laptop repaired 3 days later
  • Years before Tinder we pitched this dating app to Heineken – didn’t get the deal – and all I can remember is the awful flowery shirt I wore to the meeting, and this huge “Heineken” logo on top of the building

Believe me when I say: if I can do it, you certainly can too! Don’t forget to play ;-)

In 2017 I started working on Crest, a goal planning and journaling app. I’m writing about that journey here on LearnAppMaking.com. Both sharing my insights and ideas, and creating tutorials based on the strategies that I use. Read more here.

“Here’s to the crazy ones. The rebels. The troublemakers. The ones who see things differently. While some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world, are the ones who do.” — Steve Jobs, 1997
