BisikDuit: Expense Tracking by Voice, Locked on Your Phone

bisikduit.com Observed source
Editorial interest 84/100 Selection signal · not a rating of the site

An Indonesian expense tracker that turns spoken, everyday descriptions into categorized transactions, encrypting the records on the user’s phone.

Landing page captured for the 2026-09-06 issue.

Field notes

BisikDuit parses spoken Indonesian purchase descriptions into amount, category, wallet, and date, then describes encrypting each record on the phone before storage. Its key model separates a passphrase-derived private key from a random household key, with AES-GCM 256-bit encryption and PBKDF2 at 600,000 iterations. The site also documents a meaningful boundary: voice input is sent to Google for recognition, while typed entry avoids that service. Exports are assembled locally as monthly or full-history CSV files.
