I published my first two apps, party games, at 16. Today four apps are on the App Store, with four more on the way. I build an app when something bugs me in daily life and nothing out there fits.
I wanted a group kitty that everyone adds to themselves, on iPhone and on the Mac, and that shows where the money goes. Teilo works out to the cent who owes whom and settles up with as few payments as possible. For trips, shared flats, couples or parties.
Before, I logged every workout awkwardly in the Notes app. The apps on the store did not match what I wanted, and I did not want to depend on a provider without knowing what would happen to the app. Now I log sets in seconds, see my progress and train with Apple Watch.
With lots of letters and invoices you lose track quickly. I am a big fan of going paperless, but nothing may get lost, and I want to search for anything, anytime, anywhere. Paperkeep scans, recognises the text right on the device and keeps deadlines and warranties in view.
Learn vocabulary with numbered flashcards, like the ones in a cardboard box. Snap the word list in your schoolbook and enter the test date. The app spreads the new words over the days until the test and goes through all of them again the day before.
The mileage log that keeps itself. Odira detects trips automatically, asks “business or private?” when you get out and creates the report for the tax office. For Switzerland, Germany and Austria; everything stays on the iPhone.
The job-report app for service tradespeople. Record time, materials, photos and signature on site, send the PDF report right away and turn it into a quote and a Swiss QR invoice. No account, no server.
Log grades and calculate averages per subject, with weighting and grading systems from around the world. For students and parents.
Sort photos and videos with a swipe: keep, delete or hide, straight into the albums of the Photos app. For iPhone, iPad and Mac.
My first apps, built and published myself at 16.
The ideas come from my own day: training, paperwork, driving, shared expenses. I sketch flows and screens, write the copy and decide what goes in and what stays out.
Everything is built in SwiftUI and tested on real devices. Translations, screenshots, store copy and the submission to Apple follow.
