Frequently asked questions
Harbiz is popular in Spain. Does CatalysFit work as well there?
Yes. CatalysFit ships with full native Spanish support — every screen, every email, every AI-generated program is authored in Spanish, not machine-translated. You can use it identically in Madrid, Barcelona, Valencia, or Mexico City. The difference is CatalysFit is multilingual by default, so if you later take on a French-speaking or English-speaking client, you don't need to switch tools.
Harbiz has a native branded app. Can CatalysFit match that?
CatalysFit offers white-label on every plan — your brand name, logo, colors, and the option to hide "Powered by CatalysFit" entirely. The difference is delivery: Harbiz ships a branded native app your clients download; CatalysFit gives clients a web portal link (plus our own native apps on App Store / Google Play if they prefer). Web portal has 0 install friction and updates instantly. For most independent trainers this is actually preferable.
How does CatalysFit AI compare to what Harbiz offers?
Harbiz focuses on business management — scheduling, billing, client tracking — and ships limited AI features. CatalysFit is AI-first: program generation, nutrition plans, plateau detection, Smart Inbox (urgency-triaged messages), AI Research Feed (daily PubMed summaries), and AI Content Studio (Instagram posts). For coaches whose time is eaten by programming and content creation, the AI stack is the difference.
Does Harbiz work outside Spain?
Harbiz technically works internationally but the product, pricing, and support are Spanish-first — English support and French/Portuguese interfaces are partial. CatalysFit is designed multi-region from day one: native Portuguese, English, French, Spanish, USD/EUR/BRL pricing that auto-adjusts per visitor location, and fully translated email flows.
Can I try CatalysFit before committing?
Yes — 14-day free trial, full access, no credit card required. You can generate a program for a real client, send them the portal link, test the Smart Inbox, run the Research Feed, and fully evaluate if CatalysFit replaces your current workflow. If after 14 days you decide not to continue, nothing charges. If you subscribe, the monthly plan cancels anytime; annual is also cancellable.
