Small tools,
built to work.

A working collection of web utilities — interactive, offline-capable, and built without frameworks or app stores.

Built by Avin — self-taught developer, atsixty.com. Each tool here is a real deliverable: something that installs on your phone, works without internet, and does exactly one job well. The code is written from scratch, deployed on a self-managed VPS, and audited for performance.
