How to Use Track Expenses Offline

A simple workflow built into every LetzGo experience.

01

Seamless Transition to Offline

When cell reception drops in high valleys, flights, or subways, LetzGo switches to local SQLite storage seamlessly.

02

Log & Browse Instantly

Add expenses, view schedules, check packing lists, and see running balances without waiting for a server spinner.

03

Automatic Background Sync

The second your phone picks up Wi-Fi or 4G/5G, LetzGo resolves sequence clocks and syncs all changes with the group.
