AI-Created · iOS
Careful little apps for iPhone.
Eight games and tools, made by one person. Private by default, on-device, no ads, no tracking — most are a single one-time purchase.
The chrome is grey on purpose. The color is the apps.
What they all have in common
A point of view, not a feature list.
- Private by default
- Nothing leaves your device unless you ask it to.
- On-device
- The work happens on your iPhone, not on a server.
- No ads
- None. Not now, not later.
- No tracking
- No analytics profile, no third parties watching.
- No nonsense
- One-time purchases where we can. Competitively priced subscriptions where we have to. No nagging.
Who builds them
Designed and built by the same person.
Marco has spent decades shipping web and mobile software — and just as long as a senior product designer who lives in UX. He figures out what people actually need, designs exactly that, then writes the code to build it. No handoffs, no telephone game between design and engineering.
AI tools help with the typing. The judgment, the interaction design, and the testing are his. Every app here is carefully engineered, reviewed, and put through real-world testing before it reaches the App Store — no shortcuts, no vibe-coded filler.
