About Rupin (formerly Udhaar Book)
Rupin, previously circulated under the name Udhaar Book, is a business application from Toko Lab Inc. that carries forward the familiar credit-book workflow in a modern package. The app is distributed under the package identifier com.oscarudhaarapp, so it installs alongside or replaces the earlier Udhaar Book build on the same device. A Rebrand With Familiar Roots The shift from Udhaar Book to Rupin keeps the identity of a ledger-style business tool intact. Anyone who kept records under the previous name will recognise the purpose immediately, and the new label simply reflects how the developer now presents the product. Business Category Focus Rupin sits squarely in the business category, which frames it as a working tool for day-to-day commercial record keeping rather than a leisure or media app. That positioning is consistent with the earlier Udhaar Book branding, where the emphasis was on tracking what is owed and what is received. Device Requirements And Storage The build requires Android 8.0 or newer. The current package weighs 173.5 MB, so it is worth confirming you have room to spare before installing, and newer devices will handle the footprint comfortably. Release And Developer Details The latest build is version 32.9.2, dated 2026-10-02, and comes from Toko Lab Inc.
