Apps and games that keep to themselves.

Seven private apps for iPhone, iPad and Apple Watch: no tracking, no accounts with us, and your data is never sent to us. And two games: Runo 51: A Cyberpunk Kalevala, a story-rich cyberpunk RPG of stealth and hacking in an alternate-history Finland, for PC and Mac on Steam, and Sleep Dungeon, a pixel-art roguelike RPG for iPhone that runs on your sleep.

Runo 51A Cyberpunk Kalevala

Nuclear war. Nuclear winter. Finland sang itself a shield.

Finland, 1988 — five years after the end of the world. A murdered lineman, raked back from the dead and invisible to the network, walks where its machines can't look.

Sleep Dungeon

A dungeon run while you sleep.

Equip your hero at bedtime; the longer your sleep window, the deeper they can go. In the morning, play the night's run door by door, or watch it on autoplay, and bring home the loot.

New in 1.0.2: Game Center achievements, a weekly boss leaderboard and a tougher climb.

Research

Teaching AI to judge what can’t be proven.

Software that a test or a proof can check is largely within reach of today's AI. Stationify Research works where neither can help: on whether something is coherent, natural, useful, genuinely good. Our AI system makes complete, original software end to end, judges what it made, finds where it falls short and writes its next version. A new version only counts as better when it beats the last one in the same fixed evaluation, on the same inputs.

Think of picking every square with a traffic light in a CAPTCHA. We're still picking squares. They've just become a lot more complicated.

Quality score, version by version

Each point is one version of the system. Versions 1 to 10, built between 10 and 12 October 2026, were scored the same way on the same inputs. From version 11, each version is scored on a newer, fixed test with its own scale, so the second line doesn't continue the first. The dotted stretches pass version 13, which has no score on the newer test yet, and version 16, which was not kept.

The studio

A small studio in Helsinki, making software that respects you.

Founded in 2026 by Perttu Salmenjoki, Stationify Oy designs, builds and supports every app and game itself, and runs its own AI research. Good apps are invisible, dependable and honest, and they don’t need your data to be any of those things.

  1. Private by design

    No accounts of ours, no analytics SDKs, no ads, no tracking. Your health data, recordings, plants and saved games stay with you — on your devices, and in your own iCloud where an app syncs. There is no server of ours for them to go to.

  2. Intelligence on the device

    In the apps, coaching, transcription, plant identification and scoring run on your iPhone and Apple Watch with Apple’s on-device frameworks, including Apple Intelligence where your iPhone has it — never in someone else’s cloud.

  3. Built to be relied on

    Native apps for iPhone, iPad and Apple Watch, and a game for PC and Mac, updated often and answered by the person who wrote them. Honest pricing, and free tiers that stay useful.
