Native speakers wanted.

My apps are available in 16 languages. I speak German and English fluently — the other translations were created with great care, but might sound more natural in some places. That's where you come in.

§ 01

The situation.

Klaus Mack Software is a one-person studio. For translations into French, Italian, Spanish, Dutch, Portuguese, Danish, Swedish, Norwegian, Turkish, Russian, Japanese, Korean and Chinese, I rely on modern translation technology and very careful reviews.

Even so, a native speaker often spots phrases that are understandable but don't sound quite natural — the typical Apple-style address (formal vs. informal), regional quirks, or small stylistic inconsistencies. That's exactly where I need your help.

§ 03

How it works.

/ 01

Install the app.

Download one of my apps from the App Store and switch the language to your native one. Take a look around — menus, dialogs, forms, error messages.

/ 02

Note what stands out.

Are texts unidiomatic? Wrong form of address? A word nobody uses in your region? Typos? Note everything that catches your eye — even small things.

/ 03

Send me a message.

Send your notes by email. Ideally with a screenshot and a suggested fix, but a rough list helps a lot too. I'll get back to you personally.

/ 04

A small thank you.

For serious feedback, you'll receive a promo code for the Pro version of one of my apps if you'd like one. If you don't need one: a heartfelt thank you and a mention in the release notes.

§ 04

Write to me.

A short email with the language and a few examples is more than enough. I'll reply personally.
