New one is up: Kreis.
It came out of my cycling club near Salzburg. Every family bike day ends the same way - a few hundred photos scattered across phones and chats, and afterwards nobody can find
anything.
So we built one private album for one group. In September we tested it on the real thing: people scanned a QR code at the stations and their photos went straight into the
shared album — no app to install, no account. A hundred by the evening. 154 now, because
people kept adding theirs afterwards.
It sorts photos by day on its own, keeps likes and comments next to the pictures, and
holds everything in full quality. No ads, no tracking.
Two of us built it: I do product, releases and support, my partner does web. On the App
Store and Google Play — and the next features I'm building with my clubmates first.

It records your path over GPS and always points you back home — fully offline, using just GPS and a compass. Built for mushroom foragers, it works for anyone who wanders off the trail.
The idea and most of the engineering are Ivan's @Ivan Lukichev . I owned the part that takes a strong product and gets it into people's hands:
• Localization into 8 languages (EN, DE, PL, FR, CS, FI, SV, RU)
• Full ASO — names, subtitles, keywords, descriptions per locale
• App Store Connect setup, subscriptions, and submission
• Handling the App Review process end to end, including a Guideline 2.1 review round
Result: approved and live on the App Store 🌲 Just shipped: VERT — Altimeter & Ski Tracker, live on the App Store. 🏔️
An honest altimeter and hike/ski tracker for iPhone, built around one idea: never lose your day, and never need a signal.
The craft decisions I'm proudest of:
→ Crash-safe by design. Every recording writes to disk continuously — no "press stop to save," no lost day, ever. I tested it against real SIGKILLs.
→ Offline-first, for real. Barometer for altitude, no account, no cloud. Nothing leaves the phone.
→ Honest numbers. The ± you see is the accuracy the OS actually reports — I refused to fake a comforting figure.
→ Real photographs, not stock. The backgrounds are my own shots from the Austrian Alps, keyed to the altitude in their EXIF.
→ Buy once, $1.99. No subscription. The paywall isn't a hostage situation — the app is fully useful free.
Ten languages. Made in Austria, on the trails it was built for. Version one — with plenty more, and Android, on the way.
