Small apps, made with obsessive care.
revOS is an independent studio in Istanbul making focused apps for iPhone and Mac. Each one does a single job completely — no bloat, no needless accounts.
Turkish 101 Okey. A new rule every hand.
A rule is picked at the start of every hand and everyone opens to it. Runs, sets, pairs — 50 different rules, real opponents and the table's most thrilling moment: the penalty draw.
Five apps. One desk.
Each one targets a single, specific annoyance — and solves it without compromise.
Your .env files, encrypted in the Keychain.
BuildingPaste plain text, keep code indentation.
BuildingCatches Time Machine's silent failures.
PlannedAn on-device email tone coach.
PlannedTranscribes and summarizes meetings on-device.
PlannedWe build software the way it used to be built: one developer, one desk, one problem at a time. Every app ships small, works offline wherever it can, and stays out of your way until you need it.
A few rules, held without exception.
Constraints are the feature. They force every decision to be deliberate.
One problem, solved completely
Every app targets a single pain and resolves it with no half-measures. If a feature can't justify itself, it doesn't ship.
Native to the platform
Mac tools are written in SwiftUI with Apple frameworks — no Electron. Mobile apps are tuned to feel right on a real device.
Private by default
The Mac tools run fully offline — even NamingAI's AI stays on-device. When the cloud is needed, it's used only for that job.
Fair pricing, fair play
Mac utilities are a one-time purchase. Amerikano 101 has no paid loot boxes, and every move is validated on the server.
Small enough to finish
Each app is scoped to ship in a few focused weeks. That constraint is the feature.
Quiet by design
Most of them live in the menu bar or a right-click. They do their job and stay out of the way until you need them.
What's shipping, and when.
