An offline-first Android business app for scheduling lessons, keeping teaching notes, tracking attendance, and reconciling tutor payments.

Landing page captured for the 2026-08-31 issue.

Field notes

CopperPen is organized around the daily sequence of independent tutoring: view the next lesson, review what happened last time, record attendance and notes, then reconcile payment. Its stated offline model keeps data on the device and includes CSV or JSON export, while reporting extends beyond income to teaching hours, no-shows, and unpaid balances. The page says the Android app is in development and offers free use for up to five active students, but does not expose a build or download flow.
