Fact Lab
A native iOS and iPad app for multiplication fluency, with no accounts, ads, or subscriptions.
Fact Lab is a times-tables practice app I built as a local, direct-install alternative to the paywalled drills.
It covers facts 0 to 12, plus division, missing-factor, sprint, and assessment modes, with an adaptive queue that orders due, weak, and new facts and tracks mastery on the device (a fact counts as known after three fast correct answers spaced at least four hours apart). No accounts, ads, telemetry, or subscriptions, everything stays local.
