FAQ
Frequently asked questions
Which AI platforms does LimitWatch support?
LimitWatch works with Claude, Codex, Gemini, Cursor, OpenRouter, Copilot, and many more. The Mac app automatically detects supported tools and reads quota data locally.
Do I need both the Mac and iOS apps?
The Mac app is the data source — it reads quota information from your locally installed AI tools. The iOS app (and Apple Watch) displays that data via iCloud sync. You need the Mac app running on at least one machine.
Does my data leave my machine?
Quota snapshots sync between your own devices through your personal iCloud account. No data is sent to our servers. We use Sentry for anonymous crash reporting only, which you can disable.
How does sync work?
LimitWatch uses iCloud CloudKit and Key-Value Store. If your Mac and iPhone share the same Apple ID, sync is automatic — no accounts to create, no pairing codes needed. For different Apple IDs, QR-code pairing is available (Pro feature).
What widgets are available?
Six layouts: overview, paged list, minimal list, logo list, ring strip, and ring focus. Available on the iPhone home screen, lock screen, and Apple Watch complications. Configurable platform count and display metrics.
What is the difference between Lite and Pro?
Lite unlocks all widget layouts, quota alerts, trend charts, and billing analytics for one Mac source. Pro adds unlimited Mac sources, session archive with full transcript history, data export, and cross-account pairing.
Can I get a refund?
App Store subscriptions can be refunded through Apple. Go to reportaproblem.apple.com within 14 days of purchase.
Is the Mac app sandboxed?
No. The Mac app needs to read configuration files from AI tools (which live outside the sandbox), listen on a local Unix socket, and optionally control terminal apps for session jumping. This is why it is distributed as a direct download rather than through the Mac App Store.
