Jizailog

Overview
Jizailog is a local-first GPS tracker built to escape the subscription hell. Track where you go, save it on your phone using SQLite — no cloud account required. Your data stays on your device by default.
Want to sync across devices or share with your family, team, jogging club, or co-workers? Just pay a one-time fee to connect your own Supabase database. No recurring subscriptions — you only cover your own infrastructure costs. It’s the digital DIY era with AI support.
Concept
We provide a secure app and API. Users own database, GPS data, and privacy. As long as Supabase and Cloudflare provide their services, JizaiLog will keep saving you money compared to subscription-based alternatives.
