Our apps.

Three web tools that are live, free and need no account, and two Mac apps that are built and not yet released.

A short tour of the work

A 34-second loop: Calendar, the Utility & EV Calculator and the Car Loan Calculator, the two Mac apps, and the *.brunei.app wildcard.

The month is an illustration: October 2026 on the government week, with one leave day bridging Friday to Sunday. The electricity reading, 750 kWh, follows the published residential blocks to BND 18.00. The loan is a sample of BND 60,000 over 5 years at 3.50% flat, as the Car Loan Calculator works it out: BND 1,175.00 a month and BND 10,500.00 interest in total. The Pointsistant and USMS Widget scenes are illustrations with made-up figures, not screen recordings.
