Diby helps fitness coaches manage clients, programs, progress, and payments without spreadsheets, DMs, or juggling multiple tools.
Built by and with coaches. Free to apply. No obligation to join.
The real problem
If you are a fitness coach, you probably deal with this every week:
Nothing talks to each other. Everything breaks at scale.

What coaches use today
Most coaches end up stacking tools like this:
Trainer app for workouts
Build and assign programs in one place
Google Sheets for tracking
One dashboard for every client
WhatsApp or Instagram for communication
Photos, check-ins, and history in one place
Notion or Docs for notes
Track and manage payments without spreadsheets
Stripe for payments
Payments tracked elsewhere or not at all
It works for 5 clients.
It becomes chaos at 20.
It breaks completely at 50.

The solution
Diby is the infrastructure behind your coaching business.
No spreadsheets. No duct-taped tools. No complexity.

“I've been using Evernote for 3 years to manage my training programs, but it wasn't built for coaches. When I tested Diby, I finally found what I needed - actual workout programming, client tracking, and proper exercise libraries. Can't wait for the full launch to migrate all my clients over.”

“As a CrossFit athlete and CF-L1 trainer, I need a tool that keeps up with the intensity of my workouts while staying simple for my clients. This platform helps me manage WODs, bootcamps, and 1:1 sessions without wasting time on admin, so I can focus on training and helping my athletes grow.”

“Before Diby, I was juggling WhatsApp, Excel, and three different apps just to manage my clients. The prototype already shows me how everything will be in one place - scheduling, payments, progress tracking. Just having the booking system alone will save me 10 hours a week of back-and-forth messages.”
