Vaultsum is an offline-first expense tracker for Android. It reads payment notifications from Google Pay, Phonepe, Paytm and your bank's SMS alerts, turning them into a one-tap transaction - no manual entry. No sign-up needed for the core app, no ads, and your data stays in an encrypted database on your device. Budgets warn you before you overspend, Insights show where your money actually went, and an optional Groups feature splits shared expenses with friends.
