OmniAppHub

Tiny, single-purpose web apps for learning and play, all in one place.

OmniAppHub is a small, hand-built collection of focused tools for learning and short, repeatable practice. Every app here does exactly one thing — drill chess coordinates, identify a piano pitch, generate a math worksheet, flip a Python flashcard, track a child's chores — and tries to do that one thing well. There are no accounts to create, no email addresses to hand over, no installers, and no upsell to a “Pro” version. Open a tab, drill for two or three minutes, close the tab, and get on with your day.

The Site is built for students brushing up between classes, parents motivating young children with positive reinforcement, hobbyists keeping a niche skill warm, and teachers who need a free printable in a hurry. Pages load fast on bad connections, work on phones, and stay simple enough to read on a school Chromebook.
