Frequently asked questions
Jonas Fitness scores D on the API Report Card. Jonas Fitness markets an open API that powers a 30+ Channel Partner ecosystem, but there is no public developer portal, self-serve key signup, published docs, or rate limits. API and webhook access is granted only to vetted partners after a BD process.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
Jonas Fitness, Inc. is the publisher of the Compete Member Management Software suite for health clubs, gyms, hospital wellness centers, and multi-site fitness operators.

Club staff use Compete daily to: enroll new members and execute contracts (Join Online), run front-desk check-in (including barcode/RFID/biometric), ring POS sales for retail/F&B, run sales-floor prospecting and lead workflows, manage class and personal-training schedules, generate monthly EFT dues drafts and post payments, run AR collections and write-offs, manage staff schedules and commissions, and produce financial and operational reports.

Founded 1981; ~45 years old. The founder pioneered EFT for the health-club industry, and Jonas Fitness claims to have been the first fitness-management system to integrate software with payment processing.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Jonas Fitness API and MCP server so AI agents and internal tools can read and write Jonas Fitness data. See the Jonas Fitness integration docs at supergood.ai/docs/jonas-fitness-api.
