Every app grew out of a real need and is built here by one person. What they share: your data stays on your device, there is no advertising and there are no trackers. How far an app is stands next to it – and that only changes when App Store Connect proves it.
GeoShot
Photos & videos with a GPS stamp
In the App Storeavailable
Add location, address, map and time to photos and videos right away – simple proof for private handovers, damage and deliveries.
The stamp is in the image
Location, address, map and time are burned into the photo or video, not just written next to it. Videos carry start and end time.
Proof, not a note
Born out of a real need in security work: document handovers, damage and deliveries so that the recording speaks for itself.
Stays on your device

Your data stays with you
BioPulse stores your data only on your own devices. No account, no ads, no tracking. Face ID can protect the whole app or just BioFlow, and a backup file takes your entries to a new iPhone.
Show numbers, don't judge
BioPulse reads your Apple Health data and explains what is behind each value. For guidance only, with no diagnoses and no treatment advice. BioPulse is not a medical device and does not replace medical advice.
How much does BioPulse cost?
BioPulse is free to download. Today, the last 7 days, every score with its explanation, the journal and the data export stay free. BioPulse Pro is an optional monthly or yearly subscription that unlocks long-term history, trends, connections, the PDF report and more. You can see the current prices on the App Store.

ProjektPilot
Plan projects, calculate dates backwards
In testingcoming to the App Store
Structure tasks, clarify who is responsible and calculate dates backwards from the project deadline – with working days, public holidays per German state and buffers.
Backwards from the goal
You name the deadline, the app calculates the tasks backwards – with working days, buffers and dependencies.
Public holidays per state
The scheduler knows the statutory holidays of each German state and takes them out, instead of assuming plain working days.
On all three devices
iPhone, iPad and Mac, synced through your own iCloud. The provider gets none of it.
A jump game for in between: four enemy types, three boss patterns and three difficulty levels – no ads, no account, no tracking.
No account, no ads
No sign-up, no advertising, no analytics tools. Your progress and settings stay on your device.
Coins without pressure
Five coin packs with amounts that match the shop prices exactly, a permanent doubler, a starter pack and two theme packs, each with characters and its own world theme. No countdown, no nagging.
Game Center if you like
Best scores and a leaderboard per difficulty, plus 75 achievements via Apple's Game Center – optional, the game works without it.
