Kala Sang Waktu

Have you ever felt like a regular digital clock just displays cold, meaningless numbers?

Kala — Sang Waktu is an analog clock and calendar application for Indonesian culture, presenting time as knowledge, philosophy, and harmony with nature.

One circle, many ways to read time. Kala combines the Cakra Kala analog clock with cultural patterns and five cross-traditional calendar systems, calculated mathematically, precisely, and transparently.
