Personal Training Session Tracker

Stop tracking sessions in notes, chats, or spreadsheets. Custly is a personal training session tracker that logs each visit, package balance, and client status in seconds.

What Trainers Need to Track Daily

Sessions remaining

Know exactly how many sessions each client has left in their package, and avoid confusion at check-in.

Visit history

Keep a clear timeline of past visits so you can quickly check consistency and follow up with inactive clients.

Balance and membership status

Track prepaid balances and active memberships in one view, whether you train in a gym, studio, or mobile setup.

How Custly Fits Your Workflow

1. Add client and package

Create a client profile and assign their prepaid training package in under one minute.

2. Deduct session after each visit

After training, tap once to deduct a session and keep records accurate.

3. Stay offline, sync when needed

Work fully offline on the floor. Upgrade to a paid plan for cloud sync and cloud backup across devices.
