Your AI usage limits, at a glance.
See how much of your Claude, Codex, Gemini and Cursor limits you have left, and when they reset: on your Windows desktop, your phone and your home screen.
Download
Start with the Windows app: it reads your limits from the accounts you're already signed in to. Add the Android app to carry them to your phone; the Windows app shares with it directly.
If the Android app closed as soon as you opened it, install the latest version. The startup crash in 1.0.0 and 1.0.1 was fixed in 1.1, and updates install over earlier versions.
UsageNotch for Android
The desktop dock in your pocket, in liquid glass: the same rings and logos, widgets in any size, a live countdown, budgets, alerts, a Quick Settings tile, a 90-day history and an offline mode. Open the APK on your phone to install it.

On your PC, open UsageNotch → Settings → Phone and turn on sharing. On your phone, tap Scan QR code. No extra app, no files to copy. Scanning with the phone's camera works too, even before the app is installed.

You only need the phone steps if you want the Android app.
- Run UsageNotch on Windows. Open
UsageNotch.exe. If SmartScreen appears, choose More info → Run anyway. Connect Claude, Codex, Gemini or Cursor in Settings. - Turn on phone sharing. Open Settings → Phone and switch on Share usage with paired phones. Allow Private networks if Windows Firewall asks. A QR code appears.
- Scan it. Install the APK, open UsageNotch and tap Scan QR code. Then add a widget or the Quick Settings tile from the Widgets tab, and turn on Live countdown or Usage alerts in Settings.
Widgets in any size
Resize freely: a single ring, a dock row or column like the desktop, or the full view with every limit. Glass that lets your wallpaper through, the desktop's colours, the real Claude, OpenAI, Gemini and Cursor marks, and a refresh button that updates from your PC.
Keeps working when your PC is off
Your sign-ins stay on Windows, so new usage is measured there. When the PC is off or you're away, the phone stays useful and never pretends.
Saved readings, live countdowns
The app and widgets keep your last readings, marked with their age, and count down to each reset. The status says PC offline, not an error.
Renewed, right on time
When a reset time passes, the limit shows Renewed, and with Reset alerts on your phone notifies you. It needs no connection at all.
Optional encrypted internet sync
Windows can upload each reading to a secret gist in your own GitHub account, encrypted with a key only your paired phone has. Turning it on takes two clicks, and your phone switches over by itself on your Wi-Fi. Get readings on mobile data, and keep the last one after the PC shuts down.
Private by design
No accounts, ads, analytics or tracking. AI sign-ins never leave Windows, and Wi-Fi pairing uses HTTPS pinned to your PC's own certificate.
Questions
Windows says “Windows protected your PC”
UsageNotch isn't code-signed with a paid certificate yet, so SmartScreen doesn't recognize it. Choose More info → Run anyway. You can compare the download with the SHA-256 checksums published on each release.
Android won't install the APK
Android asks you to allow installs from the app you downloaded it with, such as Chrome or Files. Allow it once, then open the APK again. Updates install over the existing app and keep your pairing.
The phone says “Couldn't reach your PC”
In UsageNotch on Windows, open Settings → Phone, check sharing is on and your Wi-Fi address is selected (not vEthernet or WSL). Keep both devices on the same Wi-Fi or a private VPN such as Tailscale, and allow UsageNotch on Private networks in Windows Firewall.
I used UsageNotch Link before. What now?
Update UsageNotch for Windows to 2.3 or later (it updates itself), open Settings → Phone and choose Switch to built-in. Your phone stays paired: same key, same certificate. Link is closed and removed from startup.
Can the phone check my usage without the PC?
Not new usage: only UsageNotch on Windows signs in to Claude, ChatGPT, Gemini and Cursor, and your credentials aren't copied to the phone. Saved readings, countdowns, Renewed states, history and reset alerts all work offline, and internet sync gives you the latest reading from anywhere.
