Subwatch is a subscription-tracking service designed to help people organize recurring payments, avoid surprise renewals, and understand their spending. Its platform brings subscription details into a calendar, list, and dashboard, with insights that show spending by category and compare monthly and yearly billing. Users can track monthly and annual plans, free trials, and one-time payments, and receive reminders before charges are due. Subwatch also supports multiple currencies, with totals converted to a preferred currency, and offers dark and light display modes.

The service is available through a web dashboard and Chrome extension, which can detect subscriptions from Gmail and display upcoming renewals. Users can also access their information through a Raycast extension or connect their own tools and AI assistants using the REST API and MCP integration. Subscription data syncs across these tools, and the company says it is encrypted and decrypted on the client.

Subwatch offers a free plan with tracking for up to three subscriptions.
