Tap & Tally
Tap a student, then what they did, to keep a live count of class participation, with reports and nothing leaving the laptop.
Name a class, paste the roster, and lay out the room or use a grid. During class, tap a student and then a button to count what they did, or hold a tile to mark someone absent. Reports show each class for today, this week, this month or all time, with a spreadsheet download. There’s no account: everything lives in the browser, with a backup file to move it.
