Best Harbiz alternatives in 2026.
Harbiz is solid in Spain as an all-in-one wellness platform, but it isn't the only choice. Honest list of alternatives for coaches who want the plan to re-program itself after every session instead of sitting static. The AI is optional — turn it off anytime; you keep the final say.
Why look for a Harbiz alternative.
Harbiz is good as an all-in-one wellness tool in Spain, but it's missing the piece that retains clients most: post-session adaptive AI that re-programs the plan from real client performance (not just plan generation). For many coaches, product depth, iteration speed and region-ready billing matter too. Here are the 5 best options.

How to choose.
If you need nutrition + training in one tool and work in Spain with individual clients, Harbiz is still reasonable. If you want the plan to adapt itself after every session — with USD pricing charged in pesos as a bonus — Kaizer. If you only work with English-speaking clients and need product maturity, Trainerize.
FAQ about Harbiz alternatives.
Kaizer. It's the only option on this list that automatically adjusts weights and reps after every session the client logs, and it adds a retention engine with churn alerts and a native client app. The product also works perfectly in Spanish, with prices shown in USD and charged in pesos — but the reason to pick it is the product, not the geography.
Only Kaizer. Harbiz has AI to generate plans (like many others), but no alternative on this list automatically adjusts weights and reps after every session the client logs. Kaizer recalculates the estimated 1RM with NSCA tables and re-programs upcoming sessions; the rest generate the plan once and never touch it again.
Today none of these options truly cover gyms. At Kaizer, the gym model — multi-coach dashboard, multi-location and MAU-based pricing — is on our roadmap, not available yet; today we are focused on personal trainers. Harbiz doesn't cover it either: it's built only for individual pros (PT, nutritionist, physio, yoga), with no B2B2C product.
Yes — FitSW, My PT Hub and Trainerize all have nutrition modules. Kaizer doesn't — we're deliberately training-only. Many coaches combine Kaizer (for training) with specialized nutrition tools. If you need nutrition + training in one product, Harbiz is still a valid option.
Harbiz starts around $19/mo (BASIC). Kaizer has a Free plan up to 3 clients and competitive paid tiers with adaptive AI included. Trainerize and TrueCoach are in a similar range. FitSW tends to be the most affordable. Exact pricing on each landing page.
