Lesson credit and packs
Pay for several lessons at once and spend the credit 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 your credits land automatically. Nothing is charged inside the app.
Credit is spent for you. When your coach marks a lesson paid, they take it off your balance and the lesson shows as Paid. If the balance only covers part of it, the rest stays owed.
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.
