EZbook is the simple app that tracks every client, package, and session for personal trainers, built to replace what's in your head, your spreadsheet, and your notes. It's quick, it's easy, and it's a no-brainer. Start for free. "An absolute no-brainer if you offer 1-on-1 or small group coaching! Tracking sessions and payments is so easy and quick!" — Ryan T., Personal Trainer, USA Trusted by coaches in 20+ countries. WHY TRAINERS SWITCH TO EZBOOK GET THE ADMIN OFF YOUR PLATE Every minute you're not chasing renewals or hunting through notes is a minute you're actually coaching. EZbook exists to give you that time back. LOG A SESSION IN 2 TAPS. SHARE IT WITH YOUR CLIENT IN 1. No clunky forms, no scrolling through menus. Built ground-up for the coach on the go, not the coach stuck at a desk. GET STARTED IN SECONDS No clunky onboarding, no complicated setup, no tutorial you have to sit through. Add your first client and you're logging sessions immediately. NO BLOATED FEATURES. JUST WHAT YOU NEED. No bloated dashboard, no online-programming builder you'll never touch. If a feature doesn't help you track clients, sessions, packages, and payments, it's not in EZbook. EVERYTHING YOU NEED, NOTHING YOU DON'T Log a session in 2 taps. Spend the time you saved actually coaching, not doing admin. Know exactly how many sessions each client has left. No more guessing. Catch every renewal before a package runs out. No awkward "are you renewing?" texts. Track payments with a quick tap. Always know who's paid and who hasn't. Add session notes and log PRs on the fly, with smart memory so you're not retyping. Share a live view link with clients in 1 tap. They see their sessions, balance, and progress. Zero effort for you, a polished experience for them. No app download needed on their end. No import wizard. No setup checklist. Add your first client and you're logging sessions in seconds. Whatever's scattered across notes, spreadsheets, and half your memory, you can have it in EZbook faster than it took to read this. Your data is always yours. Export your full client and session history to a spreadsheet anytime, no restrictions. Start free. No credit card needed to try it.
