Time is a personal trainer’s scarcest resource. Every hour you spend building Excel spreadsheets, answering WhatsApp messages, or searching for exercise videos on YouTube is an hour you’re not coaching, selling, or resting.
Coaching software exists to solve exactly that problem. But the market is full of options, and choosing the wrong one means paying for features you don’t use, or missing the ones you actually need.
In this guide, we compare Nexo Kinetics with TrueCoach, Trainerize, Harbiz, Mynter, and the classic Excel/Google Sheets, so you know exactly where each one fits.
Let’s be honest: most trainers start with Excel. It’s free, flexible, and you already know it. But as you grow, it becomes a problem:
TrueCoach is a North American platform very popular among strength and CrossFit coaches. It has a clean interface and a good athlete experience.
It’s a good option if you work with English-speaking athletes and don’t need to connect assessments with programming. The price climbs quickly as your client base scales.
Trainerize is a Canadian platform focused on the mass fitness and nutrition market. Widely used by gyms and online trainers.
A good option for trainers who also do nutrition coaching. For sports performance coaches, it lacks depth on the programming side and has no connection whatsoever with physical assessment data.
Harbiz is a Spanish-language platform with a presence in the Ibero-American market. It targets the online trainer with a focus on client experience.
An interesting option for the Spanish market, but without depth on the sports performance side or connection with assessment tools.
Mynter is a relatively new platform in the Spanish-speaking market with a focus on user experience and business management.
Useful if you need to manage billing, nutrition, and client communication in one place. It’s not designed for sports performance programming.
The fundamental difference between Nexo Kinetics and all the options above is a single one: Nexo Kinetics connects sports assessment with training programming automatically. No other app in this comparison does that.
Nexo Kinetics helps you create the right plan for each athlete, track their training, and keep them motivated.
The Nexo Kinetics Coach plan includes up to 50 athletes, and the basic plan up to 10. Compared with platforms that charge per client or raise the price as your base grows, the economics are very clear for growing trainers.
These are advanced periodization features that normally only exist in high-performance software (at prohibitive prices). In Nexo Kinetics, they’re included in the Coach plan and connect directly with each athlete’s assessment data.
Communication with the athlete is integrated directly into the platform. No more WhatsApp to send plans, ask how it went, or remind them of sessions. Everything in one place, with training context.
You can upload your own exercises with video directly from your phone, no computer needed, or you can add YouTube videos. Your methodology, your library, your brand. On top of the 400+ exercises included in the platform.
The Nexo Kinetics algorithm analyzes each athlete’s assessment results and generates personalized recommendations based on scientific research. It’s not a generic suggestion, it’s a prescription based on that person’s real data.
No other platform in this comparison has this functionality. TrueCoach, Trainerize, Harbiz, and Mynter are plan-delivery tools, not data-based plan-generation tools.
Summary of the most important points:
Nexo Kinetics is the right choice if:
If your focus is general fitness, nutrition, or billing management, Trainerize or Mynter can complement your workflow. But if you coach with a performance mindset, Nexo Kinetics is the only option in this comparison that closes the full loop.
The software you use isn’t an expense, it’s an investment in the quality of your work and in the time you get back every week.
Nexo Kinetics doesn’t compete only on price or isolated features. It competes on a different concept: that assessment and programming aren’t two separate steps, but one. And that changes the way you coach your athletes.
Nexo Jump measures vertical jump, contact time and RSI with millimetre precision — and the software turns that data into programs for your athletes.
