Coursion Studio is an independent studio. We make focused tools: a Mac toolkit, a drawer of everyday utilities, AI usage tracking, a performance monitor for mobile developers, and a few mobile apps for daily life. They do their work on your device, and where it fits, you pay once.
Native SwiftUI apps, each built around one job you'd otherwise hand to three apps, a website or a terminal window.
Convert images, shrink and merge PDFs, pull text out of scans, transcribe audio, cut out backgrounds and turn one picture into a full app icon set. Every tool runs on your Mac with Apple's own frameworks. No uploads, no account.
AI Stats tracks the usage limits on the AI accounts you already pay for, including Claude, ChatGPT, Codex and Gemini, and shows them in your menu bar, in widgets and on your iPhone Lock Screen. There's no AI Stats account and no AI Stats server. Your credentials stay in your Keychain.
Pounce opens apps, does sums and finds files from ⌘Space. Stash holds files mid-drag. Toggles puts your most-used switches in the menu bar. Window Manager snaps windows from the keyboard, Browser Picker sends each link to the right browser, and Reaper finds what's draining your battery.
Watch one app's memory, CPU, threads and frame rate live on an Android phone, the iOS Simulator or a real iPhone. Then let an AI read the session, or reach for bundle size, startup timing, a jank timeline and a dpm command line for CI.
Everyday apps built with Expo and React Native, with native code wherever the platform asks for it. Available on iPhone today.
A daily planner that resets at midnight, so there's no backlog waiting for you. Tell it "plan my morning" or "find a slot for the gym" and it fits the day around you.

Your AI usage limits on the Home Screen and Lock Screen, with a refresh button on the widget. One purchase covers iPhone, iPad and Mac.
Get AI Stats on the App StoreThe rules we come back to every time we start something new.
If a job can run on your Mac or phone, that's where it runs. Your files and data don't take a detour through a server you never asked for.
SwiftUI on the Mac. React Native and Expo on mobile, with Swift and Kotlin wherever a real platform API is the honest answer. Whatever sits underneath, the app should feel quick, quiet and at home.
Our Mac apps are free or a one-time purchase. When an app has a running cost behind it, like AI features in our mobile apps, it may use a subscription, and the App Store page says so up front.
One studio, many apps: utilities, developer tools, health, productivity and lifestyle. Good ideas rarely stay in one category, and shipping across them keeps the work honest.
Email goes straight to the people who build the apps. Press and partnership requests are welcome too.
