Keeping up with your kids' lessons? "I forgot the tuition envelope again." "The make-up lesson expired." "The recital clashed with sports day." LessonNote is a lesson organizer for busy parents: tuition, make-up lessons and schedules for the whole family, in one place. The core features are free. WHO IT IS FOR - Families juggling several lessons per child - Parents who want tuition amounts and payment days at a glance - Anyone who keeps missing make-up lesson deadlines - Families whose school events collide with lesson days FREE FEATURES [Tuition, handled] Register the amount and the payment day for each lesson. Reminders arrive the day before and on the day, so the cash envelope is never forgotten. See every lesson's payment status side by side. [Never lose a make-up lesson] Record the make-up date and get reminders 7 days and 3 days ahead. Tick it off when it is done. Simple, reliable make-up management. [Catch schedule clashes] Add school events - sports day, class visits - and the calendar flags any overlap with lesson days. Record how you handled it: skip, reschedule, or go ahead. [One calendar for the family] Every lesson appears on the calendar in its own color, so the family's week is clear at a glance. [Every child, separately] Manage each sibling's lessons on their own page and switch between children in a tap. PLUS FEATURES (monthly or yearly plan) [AI import from school newsletters] Photograph a newsletter or pick it from your library, and AI reads out the events. Review and confirm, and they land on your calendar in one batch - no retyping. [Clash alerts on the home screen] Overlaps between lessons and events surface on the home screen by themselves - no need to open the calendar. [Advance push notifications] Get notified ahead of time when a lesson and an event are about to collide, so you can adjust plans calmly. [Yearly tuition summary] Look back on this school year's tuition by lesson, and see what the year of lessons actually cost. HOW IT WORKS 1. Register lessons (name, day, time, tuition, color) 2. Add school events - by hand, or in one batch with Plus's AI newsletter import 3. Check today's lessons and tuition status on the home screen 4. See the month on the calendar 5. Let reminders track payment days and make-up deadlines for you PRIVACY Everything you register with the free features - lessons, children, tuition, calendar - stays on your device. It is not sent to any server. Only when you use the Plus feature "AI import from school newsletters" is the selected image sent for AI analysis. The image is not stored after analysis. Unless you use this feature, no image ever leaves your device. SUBSCRIPTION Plus is an auto-renewing subscription (monthly or yearly). Payment is charged to your Apple Account at confirmation of purchase. The exact price in your local currency is shown in the app before you confirm.
