Pupilon

Pupilon is a calm, offline planner for private tutors, teachers, and coaches. Keep your whole teaching week on one clean agenda — see today's lessons, what's coming up, and exactly how much each student still owes you, all without an account or an internet connection.

Add each student with their subject and hourly rate, then book a lesson in seconds: the price fills in automatically from the rate and the duration you pick. Mark lessons completed, flag who has paid, and Pupilon adds it up for you — earned, outstanding, and lessons taught for every student.

Highlights:
• Clean daily agenda with a tap-to-switch date strip
• Per-student billing: earned, outstanding balance, completed lessons
• Automatic lesson pricing from hourly rate × duration
• Mark lessons scheduled, completed, paid or cancelled
• Light, Dark and System themes, plus 8 languages
• 100% offline — no account, no ads, no tracking; your data stays on your device

Important: Pupilon is a personal planning and bookkeeping tool for independent tutors and educators. It runs entirely on your device with no sign-in and no internet permission, so your students' details never leave your phone.
