A term, not twelve bookings
One hour a week,for the whole term.
Every date of the term is shown before anything is committed, then booked in one press.
- The same tutor, the same hour
- Half-term left out
- 7 weeks at £24 — £168
- A free hour is free on every week left
- Carried into the next term unless they say no
What happens between two lessons
The note goes home,and comes back ticked.
Each thing to practise has seven days under it, and the tutor sees the count before the next lesson.
- What we did, and up to eight things
- A thing at nought is in red
- Shared once, to that child's family only
- A first name and a year — nothing else
- Never a text, and never to the child
Tuesday, from the front desk
Three cards that appearonly when they must.
Notes still to write, make-ups still to book, and the statements somebody is behind on.
- A day's notice earns a make-up, two a term
- Told later, it stays on the statement
- A tutor away always gives one
- One statement a family, paid in three parts
- Nothing is cancelled by the app itself
Tutors, in the teaching room
Lesson 5 of 12,and what was played.
The tutor opens the lesson, reads last week's practice counted, and writes today's before the next student.
- Android and iPhone, one codebase
- The term at a glance, day by day
- Up to eight things to practise
- Sent once, to the parent
