Built by trainers, shipped for trainers.
RKD grew out of daily frustration: Excel, lost PDFs, clients texting on Messenger. We decided to build the tool we use ourselves every day.

Qualifications
- Certified personal trainer
- Gym instructor
- Physiotherapy student
Training has been my passion for as long as I can remember. But it was only when I had enough knowledge to actually share with others that I realized this is my calling. Passing on what I know about training has been with me for years, and the results and feedback from people who worked with me push me to keep learning.
I'm the founder of the Rozwój Każdego Dnia platform. It's the motto I bring to every session with every client. My qualifications let me guide your training safely and effectively. Trust me and I'll help you reach your goals, whether it's how you feel, how you look, or how your body performs.
Let me share my passion with you. Let's start today.
Three rules that guide us
Only what works
We don't ship features we wouldn't use ourselves. Every line of code has to earn its place in a trainer's daily routine.
Privacy as standard
Client data is serious. GDPR, EU hosting, audits. Not as a checkbox, but because that's how it should be.
One user, full attention
Built for the working personal trainer. No distractions, no upsells, no features you'll never touch.
