• A calendar you’ll actually use — because it does the rest, too.

Open it and your whole day’s there: who’s coming, who’s paid, who’s behind, even a photo to jog your memory. Green = paid, red = behind. Client arrives → tap attended. Move someone → swipe. That one calendar is also your attendance record and your finances — so marking a session is updating the books.

• Start the day already knowing.

Every morning, a summary: first session, how many you’ve got, who owes you money.

• Money, without the spreadsheet.

Connect your bank once; transactions arrive on their own — tap to match each to a client and session. The “did Dave pay?” question stops existing. Prepaid packs count themselves down (“paid for 10, 4 to go”). Payment reminders go out a week or two before a block’s due — always in front, never rug-pulled.

• The policy that holds itself.

Set your late-cancel and no-show fees once; the fee lands on the client’s balance automatically, already showing in their app. No chasing, no awkward chat, no eating the cost to keep the peace.

• The moment you log it, your client knows.

Attendance, payment, fee, reschedule — their app updates instantly, with a notification. One shared record, one truth. The gap where arguments lived? Gone.
