Feedback Bites

A micro-lesson app built for phones: three-minute lessons, one quick check each, and a review deck that uses spaced repetition — cards you know come back less often, cards you miss come back tomorrow.

• Leitner boxes — 5 boxes with review gaps of 0, 1, 3, 7 and 14 days.
• Works offline — a small service worker keeps the app on your device.
• Installs like an app — add it to your home screen.
• Private — progress is stored only in this browser.
