TRNRR is still early. Instead of made-up reviews, here's what you can expect from us from day one.
Built to earn trust, not borrow it
We're building TRNRR for people who want training to feel clear, personal, and realistic to follow. That means being honest about what exists today and listening closely to feedback, notes, and suggestions from early users.
Your plan is generated around your goals, schedule, available equipment, and limitations.
The product is designed to feel beginner-friendly, practical, and easy to stick with in real life.
Early users have real influence on what we improve next. We read the feedback, look for patterns, and want the best ideas to make it into the product.
Why TRNRR exists
I first built TRNRR for myself because I was struggling to make consistent progress and couldn't find a tool that actually helped me train smarter. It turned out to be a really good idea. Now I'm building it further so it can help other people stay consistent and see real results too.
