Building LET: The Privacy-First Habit Tracker That Lives Offline

LET challenges the data-hungry habit tracker model by delivering a full-featured offline app that requires no account, subscriptions, or cloud sync. Built through AI-assisted 'vibe-coding,' it demonstrates that production-grade applications can be developed with fewer traditional engineering constraints. For privacy-conscious users and developers, it signals a growing trend toward local-first applications that prioritize user data ownership.
