Topf-Secret
A personal cookbook that keeps notes. Say what you feel like or what is in the fridge and get one recipe that fits your kitchen devices, your time and your allergies.
Workshop
What I build next to client work.
My own apps and web tools, most of them born from a problem in my everyday life. Some are on the App Store, some run in the browser, some are only just taking shape.
Try them
Publicly available, with a website and an app.
Sprachverliebt
A rare German word every day, plus proverbs, idioms and aphorisms. With meaning, pronunciation and an example. The app is in German.
events
RSVPs, bring lists, rides and photos in one place. No more WhatsApp chaos before every party. Guests need no account.
zeit
Track hours, keep an eye on projects and turn both into the invoice. Built for freelancers who are done giving money away.
Still in progress
Not public yet, only in my own daily use or still being built. If one of them interests you, drop me a line.
casa
Learn English and Spanish as a family. Learning games and a path without streak pressure.
henry
AI voice companion for kids. Parents see everything in a dashboard and can pause it at any time.
Mondbuch
Bedtime stories made from a wish, read aloud over AirPlay on the speaker in the kids' room.
Family Assistant
Reads along in WhatsApp groups and pulls out dates, tasks and deadlines. Every entry quotes the original message.
Dreierpack
A focus duel for two: each of you sets three tasks in the morning and sees the other's result at night.
Abenteuer KI
Block coding in the browser for a kids' course. Teams build games, AI supplies images and sound.
Layer
3D printing without slicer frustration on the Mac: drop in an STL, AI picks the print settings, click print. With a live monitor for the Prusa.
MailToPDF
Mac menu bar app: drag an email from Apple Mail onto the icon and get an A4 PDF. PDF attachments are saved next to it. Built for bookkeeping.
Optimaze Images
Shrinks images on the Mac right up to the point where you would see a difference. Per image the smallest format wins, measured rather than guessed.
ActionBar
GitHub builds in the Mac menu bar: the status of every repo at a glance, a notification when a run finishes.
Mail Guard
Helps spot fraudulent email in Apple Mail. Checks locally on the Mac and explains the suspicion instead of ever stamping a message as safe.
Finanzen
Household finances as a chat: upload bank statements and ask where we can save. No dashboard, the chat is the app.
takt
Approval app for my social media pipeline: review posts, approve them and spread them across time slots.
What this means for your project
Each of these projects comes from one person: idea, design, app, backend and copy. That is exactly how I work for clients. If you are planning something similar, an app, a web tool or an automation, 15 to 30 minutes are enough for an honest assessment.
