Why personal trainers need a personal CRM
Training is a relationship business. Clients renew when you remember the wedding they’re getting in shape for, ask how the knee feels after the ski trip, and notice when they’ve gone quiet for a few weeks. Most of that lives in your head or in scattered texts. A personal CRM keeps the people, their goals and when to reach out in one place on your iPhone, so no client slips away just because life got busy.
What personal trainers keep in BlackBook
- Each client’s goal and the event they’re training for, like a race, a wedding or a trip
- Life details worth asking about next session, such as a new job, a move or a new baby
- Past clients you’d like to check in with, with a reminder so it actually happens
- Who referred whom, so every referral gets a thank-you
- Physios, nutrition pros and other trainers you refer clients to and hear from
- Pulse, which suggests who to reach out to next from your notes, history and reminders
Next to your training tools, not instead of them
BlackBook isn’t built for booking, payments, programming or workout tracking. Keep those in the apps you already use. Use BlackBook for your own relationship notes and follow-ups, and keep detailed health information in the systems meant for it.
Private by design
There’s no account or login. Your notes live on your iPhone and in your own private iCloud, there are no ad SDKs, and your data is never sold. Start free with the 25 clients and referral partners who matter most to your business.

Frequently asked questions
Does BlackBook replace my scheduling or training app?
No. BlackBook doesn’t book sessions, take payments, build programs or track workouts. Keep using the tools you already use for that. BlackBook is your own list of the people you train and the check-ins you mean to make.
Who do personal trainers keep in BlackBook?
Current clients, past clients you’d like to win back, people who referred someone to you, gym staff and front-desk contacts, other trainers, physios and nutrition pros you refer to, and prospects you met on the floor or at events.
What should I keep out of BlackBook?
Keep detailed health and medical information in the systems your gym or business uses for it. BlackBook works best for relationship notes, like a client’s goal, an upcoming race or trip, who referred them and when to check in.
Is my data private?
BlackBook needs no account. Your people and notes live on your iPhone and in your own private iCloud, not on a BlackBook server. There are no ad SDKs, and your data is never sold.
