What AI software can a personal trainer use for their clients?

A trainer managing several clients over WhatsApp and loose spreadsheets loses time on the wrong things: chasing someone for a set video, rebuilding a spreadsheet because a client missed a session, answering the same progression question five times a week.

Gojan is free for trainers: every client in one place, you define the program and the AI executes and adjusts it between sessions without you having to chase anyone over WhatsApp.
