Cross-device Pomodoro and todos that sync without any sign-up

Problem: Many people want a cross-device Pomodoro and todo tool, but mainstream apps force account creation or rely on cloud services that raise privacy concerns. Someone built Pomoflow with no-sign-up sync, showing real demand, yet such tools remain fragmented and hard to migrate between.
Solution: A local-first Pomodoro + todo app that syncs peer-to-peer across devices via end-to-end encrypted WebRTC or LAN discovery, with zero servers and zero accounts. Users pair by scanning a QR code or entering a short code.
Users: Privacy-conscious developers, students, and freelancers who hate creating accounts; fans of 1-bit retro or minimal productivity tools
MVP: Pomodoro timer and todo list; WebRTC P2P pairing sync via QR or short code; all data stored locally with E2E encryption; desktop apps for Windows/macOS/Linux plus a mobile web app; no cloud backend
Revenue: One-time purchase at $5-10, open-source with a paid sync relay at $2/month, or in-app theme/sound packs
Why now: WebRTC and local-first stacks are mature with broad browser support. Account fatigue and privacy awareness keep growing among developers. A solo dev can ship an MVP using Tauri/Electron and P2P libraries quickly.
