Classroom apps
The internet king of small classroom tools.
Timers for centers. Countdowns for transitions. Random pickers for bingo. The little apps a classroom needs, built without the bloat — and built because a teacher asked for them.
Available apps
Each one lives on its own address and does one job well.

Why this exists
InetKing is a place for the small tools that make a classroom run: a timer that is actually visible from the back row, a picker that does not need an account, a countdown that does not require a download. No app store, no subscriptions, no dashboards nobody asked for.
Tell us the job you need done. If it is a good fit, we build it, put it on its own subdomain, and it shows up here for every classroom that needs the same thing.
