A few small tools I shipped and keep alive. Pick the build for your device — free, open source, and your data never leaves your machine.

Wiz

A vocabulary flashcard app that makes words stick — memory curve, spaced repetition, quiz mode, built-in SAT / ISEE / AP banks.

Memory curve — spaced repetition reschedules each word right before you'd forget it (Ebbinghaus).
Smart intervals — the better you know a word, the longer the wait; review load stays minimal.
Weak-word drill — words you keep missing get collected into a drill bank until mastered.
Per-word stats — accuracy and progress for every word on the dashboard.
Quiz mode — multiple-choice quizzes convert "known" into "mastered".
Built-in banks — SAT 2200, ISEE, and AP vocabulary included, plus favorites and a "don't know" notebook.

Choose the build for your device. Both contain the same Wiz v0.5.0 (build 260820004).

These builds are unsigned — your OS treats them as development software. Allow them once on first launch:

Android

Download the APK and tap it — Android asks to allow installs from this source.
On the prompt, enable "Install unknown apps" for your browser / file manager, then install.
When the system warns it "can't be trusted", confirm you still want to install it.

macOS

Open the DMG and drag Wiz into Applications.
First launch: right-click (Control-click) Wiz → Open → Open, to bypass Gatekeeper once.
Or go to System Settings → Privacy & Security → click "Open Anyway".
