Small, careful software for Mac, iPhone and iPad.

MetaSage is where Roger Maragh publishes his apps — tools that do one job well, and games that teach while you play.

On the App Store

The whole US market, one research desk — what changed, with the evidence.

Small bites. Big discoveries. An arcade adventure that teaches how markets move.

MacBook parts lookup for repairers and tinkerers.

Windows host with iPhone and Apple Watch apps. License the source, rebrand it with one config file, ship it as your own.

Point of sale: host, browser desk, iPhone and iPad apps, and reports — under your name.

Your own market desk on the web, iPhone, iPad and Apple Watch — as a pilot, a source licence or a hosted weekly plan.

Each comes as a pilot Roger sets up for you, a source licence with the rebrand kit, or source plus a year of updates and support.
