Small apps for the problems I kept running into.

Zatech is one developer. I make small iPhone apps for everyday problems, mine, or ones people tell me about. Each one does a single thing, and asks nothing of you to do it.

QR Barcode Scanner & Reader

Thirteen code formats, one screen.

QR codes and barcodes read from the camera, a photo or a video, and acted on straight away: open the link, join the Wi-Fi network, place the call, look at the map pin. Batch mode keeps scanning and files everything in history. It generates codes as well.

The workshop

What I'm working on next.

I build one thing at a time, so this list stays short. It changes whenever an idea turns out to be worse on a phone than it was on paper.

Six problems on a list; one gets builtDeciding

How I build

Four rules I don't break.

01

One problem per app

If a feature doesn't serve the single thing the app is for, it doesn't ship. Small apps are the only ones a solo developer can actually finish.

02

Privacy first

Nothing asks who you are, and nothing is collected that the app doesn't need to do its job. What happens on your phone stays there.

03

Feedback reaches me directly

Every suggestion lands in one inbox and is read by the person who writes the code. A good idea can be in the next release.

04

Worth the space on your phone

If an app doesn't earn its place on a home screen it shouldn't be there. No clutter, no upsells, no features nobody asked for.

Who's behind it

Hi, I'm the whole studio.

I'm Maarten, a senior iOS developer in the Netherlands. Zatech is the name on the apps I build in my spare time.

They all come from the same place: an everyday problem I ran into myself, or one somebody told me about. If I can picture using it, I build it.

Feedback is the part I like most, and the appreciation people send back is what keeps me shipping. If something is broken, or an app doesn't do the thing you need it to, write to me at support@zatech.nl.

Got a problem worth an app?

I'm always collecting them. Tell me what you keep working around.
