Why a specialist
Smaller groups, higher price points, and coaches who know every member by name. Your business lives or dies on relationships and retention, not footfall. GymOS is built around that, from the first lead enquiry to the hundredth session.
GymOS was built from the ground-up with the modern fitness operator in mind. Rather than endless, disjointed bold-ons, the GymOS platform is one cohesive solution.
Successful fitness businesses are built on strong member retention. GymOS spots members drifting away before they cancel, enabling you to act immediately.
GymOS provides over 350 features in one platform, for one monthly fee. Drop the patchwork of booking tools, CRMs, email apps, spreadsheets, and dubious AI slop.
Leading the charge
Since GymOS launched in 2019 (formally known as Quoox), we have built and maintained a reputation for one of the most innovative & comprehensive gym management products on the market. Whilst many systems have stayed largely unchanged for five or more years (except for raising prices, obviously), the GymOS of today is endlessly evolving to meet the needs of gym owners tomorrow.
Let us highlight just a few of our new features from 2026 alone:
Business metrics (2026 edition)
Real-time KPIs for the things an SGPT gym actually runs on: recurring revenue, retention, attendance, lead conversion and cancellations. No exports, no spreadsheets, no guesswork.
Ask Alphie™
Alphie lives inside GymOS and at the core of your business operations, rather than being an AI bolt-on (creating a raft of data protection and privacy issues). Ask Alphie a question in plain English and get straight to the answer in seconds.
“Who is at risk of leaving?”“Who is on the 7pm SGPT?”“Whose trials ends this week?”
Alphie’s skill sets are constantly enhanced in line with our feature updates
Konduo™
Ensuring your coaches can stay in touch with members without breaching data privacy or your duty of care is a well-known headache for gyms. Konduo™ in-app calling in GymOS is the first in a gym management system, and it’s fully integrated workflows provide the solution long sought by fitness business owners.
Conversations - Launching October 2026
When it launched, GymOS was the first gym management system to provide fully two-way email and SMS communications. Many systems still don’t.
Conversations is our reimagining of messaging for 2026, designed to deliver flexibility and meet the needs of the modern premium training gym.
