For tutors, coaches and instructors
Every lesson stamped. Nobody argues about the count.
Your students prepay for 10 lessons. Three weeks later nobody remembers if it was 6 or 7 left. Stampbook is a stamp card that lives in your browser.
Open the app Free for 3 active packs. No sign-up.
How it works
- Add a student's pack: how many lessons, what they paid, how long it is valid.
- After each lesson, tap the next circle. The date goes on the stamp.
- When one is left, copy a ready-made renewal note. Pro: send a balance link the student can open.
Unearned money, visible
See what students have paid for but not yet taken. Lapsed packs are listed, and what to do about them is your call.

When the last lesson is stamped, start the next pack with the same terms.
Notes per lesson
What you covered and what to do next time, kept beside the date.
Pay once
Price and checkout link are placeholders until payments are set up.
Questions
What if I clear my browser data?
The stamps go with it. Use Backup now and then, and restore from the file. Installing the page to your home screen does not change this.
Does the balance link show my other students?
No. The link carries one student's name, lesson dates and count, packed into the address itself. Anyone with the link can read it, so share it only with that student.
Does it handle payments or reminders?
No. It counts lessons and money already paid. It sends nothing for you.
Can I use it on my phone?
Yes. Open the page in your phone browser and add it to the home screen. It works offline once loaded.
