Orthonormal Studio
Apps & Software
The studio
Good software starts with clear thinking.
Orthonormal Studio is an independent software studio. This is where apps and programs are made – from games to tools for everyday life. The first ideas date back to 2024; since 2026 the studio has existed officially.

For the little ones Discover divisors, multiples and rhythm by playing – with very easy signals to start with.
For grown-ups Tricky signals with nebulae, echoes and several suns. Pure logic, every one with exactly one solution.
For every ear Every solution makes music: your planets play chords in three-four time.

Behind the studio
Hello, I’m Christian.
I studied theoretical mathematics and computer science and am currently writing my master’s thesis in computer graphics, on Markov chain Monte Carlo methods. At Orthonormal Studio I develop software that I like to use myself: carefully built, reduced to the essentials and mathematically sound.
How I work
Calm, not noise
No ads, no pop-ups, no flood of notifications. My apps don’t push themselves on you – they are there when you need them.
Your data is yours
No tracking, no account, no server of my own. What you do in an app stays on your devices and in your own iCloud.
One pair of hands
Concept, design, sound and code all come from me. That way everything fits together in the end.
Fair prices
As a rule, you can try and use my apps for free. If you want more, you get it with Plus or Pro – as a subscription or a one-time purchase, at a fair price. That is what keeps the studio going, instead of ads or your data.
Thank you for reading this far. I am open to freelance projects – you can reach me via the contact form. And if you like games: at Gradient Wolf I will be making games for Steam.
