Lesson credit and packs
Pay your coach up front for lesson credit and spend it as you train. Where that balance lives, and which coach it belongs to.
Buy a lesson pack sits on your coach's page. A pack is a bundle at a fixed price: you pay one amount and get a larger amount of lesson credit with that coach.
You pay the coach directly, the same way you pay for a lesson, then tap I've paid. They review it and the credit lands on your balance automatically. Nothing is charged inside the app.
Credit is spent for you. When you book with that coach, the app takes the lesson's price off your balance and the lesson counts as paid. If the balance only covers part of it, the rest stays owed. Cancel and the credit comes back.
Lesson credit in Settings shows what's left with each coach, and History lists every time credit went in or came off. Credit belongs to one coach and doesn't move between them.
