For the first few
Claim a spot Reference deal: I work for your good word
I am building my client portfolio right now. So for the first projects: heavily reduced rates, smaller ones even free — in return I may showcase your project as a reference and quote you. A fair deal. And because quality beats quantity, I deliberately take on only a few projects at a time.
Not sure what you need? I advise honestly — and will tell you when the cheaper option is enough for you.
AI in the mix? I have hands-on experience with AI integration and automation — just bring it up.
All prices are non-binding "from" figures and final prices (as a small business under § 19 UStG, no VAT). You get your fixed price after the free initial call — before the project starts.

About me
One person. My own apps. Zero trackers.
Behind Dangel Studio is a single developer building software that just does its job — no detours, no buzzwords, no nosy data collection.
Three things matter to me: the apps should be fast, work reliably offline and treat your data with respect. Every app is built in-house — from the idea through the design to the final test.

Frequently asked
Good to know
Answers to the most common questions about the apps and working together.
Which apps does Dangel Studio offer?
A growing collection of my own apps that serve as work samples of how I build — such as Haushaltsbuch Pro, Gym-Logbuch and Schichtkalender Pro. Most are currently in beta; you can find them all in the "Apps" section.
Do the apps collect my data?
No. All apps work fully offline, show no ads and do not collect or transmit any personal data.
Where can I download the apps?
The apps are arriving on the Google Play Store one by one. You will find all the details here on the site — feel free to reach out if you would like to try an early version.
What are the apps built with?
Natively for Android with Kotlin and Jetpack Compose (Material 3). The focus is on speed, offline capability and clean, tested logic.
Can you build my own idea?
Yes — as a website, web app or native Android app. We work out honestly in the free first call what fits your project: often a web app that runs on any device is enough; native pays off mainly for offline use, sensors or a Play Store presence.
What does an app or website cost at Dangel Studio?
A website starts from €790, a web app or custom tool from €1,900, a native Android app from €2,400 and maintenance from €39 per month. You get the final fixed price before the project starts — after a free initial call.
Who am I not the right fit for?
Large projects that need a full agency team, 24/7 support or very tight deadlines. If instead you want one direct point of contact for a focused app or website, we are a good match.
