Games & apps · Quito
pablin.me is a one-person studio making games and apps for Apple devices, one at a time. No accounts, no analytics, no network calls of their own — everything here does what it does entirely on your device.

Native to Apple's platforms, drawn from real geometry, and private by design — not by setting.
A one-button runner. Tap or hold — and what that means depends on which of eleven heroes you are: a cube jumps, a ship flies, a ball flips gravity.
iPhone & iPad · iOS 26 · Free on the App StoreA puzzle game with the runner turned round. The tape presses the one button and never changes; you place the pieces so the run gets through.
iPhone & iPad · iOS 26 · Free on the App StoreA gear puzzle. Set gears on the pegs, let the mainspring turn the crank, and every dial has to stop exactly where the level asks — then the door opens for Milo.
iPhone & iPad · iOS 17 · Free on the App StoreA watch-repair game. Twelve watches nobody came back for, six real calibers, and every part where a watchmaker would find it.
iPhone & iPad · iOS 17 · US$4.99 on the App StoreExpenses, subscriptions, debt, and goals — tracked and narrated entirely on your device. No accounts, no cloud, no analytics.
iPhone & iPad · iOS 26 · Free on the App StoreFive tools for photographs shot more than once: stack the focus, average the noise away, clear the crowd out of a square, build star trails, or keep the sharpest frame of a burst.
iPhone & iPad · iOS 27 · Free on the App StoreFrame-by-frame video for coaches: step through every frame of the clip you just shot, measure angles and airtime, compare two attempts, talk it through, and send it back slowed down.
iPhone & iPad · iOS 26 · Free on the App StoreEverything around the edit, on the Mac: copy a card to two drives and check every file, cull RAWs at the speed of the keys, merge focus brackets and night skies, then geotag, caption and export.
Mac · macOS 15 · Coming soonLight, air and focus, after the shot. Rake Plus reads how far away everything in a photo is, then clears haze, relights with real shadows, adds fog and shafts of light, and moves the focus.

Four commitments every project here is built on — decided before a single feature, not adjusted for one.
We ship AI on-device only, through Apple's own Foundation Models. No server call, no account, no analytics — it isn't a setting, because it was never a choice.
We draw interfaces from actual shapes and native components, not pictures of them. If it's on screen, it's the same geometry the code collides against.
We write Swift, SwiftUI, and Apple's own frameworks end to end. No cross-platform runtime stands between an app and the OS it ships on.
We treat a third-party package as a liability until it proves otherwise — one more thing a user trusts with their data without ever agreeing to it.

A software engineer based in Quito, Ecuador, working mostly in Swift and C#. pablin.me is where that work ships. Outside of it: books, music, and more podcasts than is reasonable.
