Catet: Catatan Chat & Jurnal

Catet is a daily notes and journal app that works 100% offline — no cloud, no accounts, no ads. All your notes are safely stored on your own device.

What makes Catet different: notes appear chat-style. Each category is a "chat room," and each note appears as a bubble — like sending a message to yourself, but neat, organized, and searchable.
