For personal trainers

Every session booked.
Every euro accounted for.

The mobile-first way to schedule clients, see exactly who owes what, and chase payments in two taps — all in under a minute a day.

Free to start · No card · Built for solo trainers
“It replaces the notebook, the spreadsheet, and the ‘wait, did they pay?’ guesswork.”
What you get

One number you can trust

See exactly who owes what — today, not a guess spread across five screens. Future bookings stay separate from real debt, so the figure you chase is always right.

Paid in one tap

Every client has a real balance wallet. Tap Pay and the app applies credit first, collects the difference, and keeps a bank-statement ledger of every euro.

Recurring, groups & templates

Book a standing weekly slot, a group session, or a one-off in seconds. Templates pre-fill the rate and duration, and clashes get flagged before you confirm.

Chase payments in two taps

Tap Remind and CheddarCheck writes the message for you — the unpaid sessions, the total, and your payment details. You just hit send.

Nobody slips away

The going-quiet radar flags any client who hasn't trained in three weeks — so a quiet drop-off surfaces while you can still win them back.

Feels like a native app

Install it to your home screen and it opens instantly — schedule and history stay viewable even on flaky gym Wi-Fi.

Your data stays yours

  • Isolated at the database level — every trainer’s clients and money are visible only to them, enforced by Postgres row-level security.
  • Export or delete anytime — download everything as CSV or JSON from Settings, or delete your account and all its data in one step.
  • No client accounts — your clients never log in or install anything; you reach them through messages you send yourself.
