Fletcher MCP vs Shellton

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.

Shellton is a native ACP cockpit and persistent SSH/Mosh terminal for developers who want to run coding agents from iPhone without moving their work into a proprietary cloud relay. RUN CLAUDE AND CODEX ON YOUR HOSTS. Connect to a saved SSH or Mosh host, choose Claude or Codex, and start or resume an agent session in the directory where your code already lives. Shellton launches the official Agent Client Protocol adapter on demand and carries the session over your existing encrypted connection—no Shellton account, relay server, or host daemon. AN AGENT INTERFACE BUILT FOR MOBILE. Follow live transcripts, reasoning, tool activity, and plans without squeezing a desktop terminal onto your phone. Approve or deny tool requests, send the next instruction by keyboard or voice, switch between conversations, and hand control back to tmux when you return to a computer. EVERY DROPPED SESSION IS A BUG. Shellton tries Mosh first on every connection. Mosh survives Wi-Fi handoffs, dead zones, and locked-screen suspends. If the server does not have mosh-server installed, Shellton transparently falls back to SSH. VOICE INPUT, ON-DEVICE. Tap the mic and dictate agent prompts or terminal commands. Supported speech engines run on your device; your audio is never sent to Shellton. KEYBOARD THAT WORKS FOR DEVELOPERS. Use a configurable accessory bar with modifier keys, arrows, and custom escape sequences. Build bars in the app or author them in YAML and import them from Files. Hyper, Meh, Kitty keyboard protocol, and tmux prefix shortcuts are supported. FULL-SCREEN TERMINAL. Use a true-color SwiftTerm terminal with Nerd Font glyphs, themes, snippets, per-host history, SSH key management, host-key verification, Live Activities, and tmux-aware navigation. YOUR DATA STAYS YOUR OWN. Shellton uses privacy-preserving product analytics for feature adoption and connection reliability. Analytics never include hostnames, addresses, usernames, commands, terminal text, credentials, voice audio, transcripts, or raw errors, and can be disabled in Settings. There is no advertising or cross-app tracking. SSH keys live in the iOS Keychain, app data remains local, and accessory-bar configuration can sync through your private iCloud container.
