Fletcher MCP vs Yaver IO

Fletcher is a privacy-first location tracker built for the AI era: it records your movement history, keeps it under your control, and lets your AI assistant answer questions about where you've been — with every access logged in plain sight. TRACK QUIETLY • Battery-friendly background tracking using significant location changes and visit detection • A clear Tracking toggle — when it's off, it's off, with an unmistakably grayed-out map • Live map that follows you, with manual zoom controls YOUR DATA, UNDER YOUR CONTROL • History lives on your device and syncs to the Fletcher sync server — or run the open Fletcher server yourself and point the app at it in Settings • No account, no email, no name: registration is an anonymous device ID • Retention you choose, from 7 days to forever — enforced locally and on the server • Delete a single point, or wipe everything locally and remotely, anytime CONNECT YOUR AI ASSISTANT (MCP) • Fletcher includes a Model Context Protocol (MCP) server — the open standard supported by Claude and other AI assistants • Generate a connection token in the app, paste it into your assistant, and ask things like "Where was I last Tuesday afternoon?" or "How often did I visit the gym this month?" • Precision control: share exact, ~100 m, or ~1 km coordinates with assistants • Revoke a token at any time — revocation takes effect immediately, even mid-session TRANSPARENCY, BUILT IN • Every assistant request is logged: what was asked, when, and how many locations were returned • Review the full request history right in the app • No analytics, no ads, no third-party SDKs EXPLORE YOUR HISTORY • Interactive history map with start and end markers, smooth even with thousands of points • Fast list view with swipe-to-delete • Sync status view with diagnostics and manual controls Fletcher is for people who want the convenience of a location-aware AI assistant without handing their movement history to a data broker. Your location data is used for one thing — your own history — and is never sold, shared, or used for advertising.
