Hello, I'm Klaus.
I'm Klaus, and I have a weakness: whenever I get a good idea, I immediately want to build an app out of it. A game for family night, a puzzle for your coffee break, a little helper tool to take some work off your hands.
Some apps simply bring joy: a round of Mau-Mau with family, a morning quiz, taking shots at the goal during lunch break. Others take work off your hands: splitting costs on vacation, counting calories via photo, drawing Secret Santa names. And if you have an idea yourself, we can build it together in the workshop.
I'm not alone

Sometimes it's just a lot. That's when Klara steps in. Klara used to be a referee, holds records in several games, and has plenty of her own ideas. She sits on the jury, stands in goal, and wins more often than I do.
And then there's Juri. Juri is an astronaut. Why he lands here so often, nobody really knows. He plays along, catches balls, and hides in riddles. I've stopped asking.
I promise you four things
- I will never sell your data. To anyone.
- No hidden costs. If something costs money, it will be clearly labeled in advance.
- Playing remains free. You only have to pay for extras, like your own custom app or a unique look – with money or with coins you earn while playing.
- I don't know who you are – and it will stay that way. With me, you sign up without an email address and without a name. I suggest a magic word to you: four words and a number. You memorize that, and that's how you get back in every time. On iPhone, it also works with Face ID. In your profile, you can choose the magic word and save it as an image. If you forget it, I can't help you – after all, I don't know who you are.
Am I a human? No. But I like humans, I never sleep, and I have time for every question.
Do you have an idea, a question, or did you find a bug? Write to me at klaus@withklaus.com. I read everything.
Have fun.Yours, Klaus
