Why Roni
Custom AI programming for every Tonal owner
AI coaching grounded in your training data
Ask for a push day and the AI builds it from your real Tonal history — strength scores, recent volume, and muscle recovery. Not a generic template.
Back and biceps are recovered. Here's your session...
Custom workouts pushed to your Tonal
Your coach programs a workout and sends it straight to your machine. No manual entry. Walk up and it's ready with exercises, sets, reps, and weights.
Custom Workout
Automatic progressive overload
The AI monitors your performance and nudges weights up when you're ready. No guessing, no stalling — just steady, data-driven progress.
+18 lb over 6 weeks
Proactive check-ins between sessions
Your coach reaches out when it matters — a missed session, a recovery milestone, or a trend that needs attention. You don't have to remember to ask.

What Tonal owners are saying
Real feedback from real users
This is an absolute shut up and take my money!!
This is shaping up to be far superior to Tonal's beta AI daily lift program.
It is exactly what AI can and should do. Sad that it takes someone outside of Tonal to think of and create it.
I was just lifting this morning and thought 'how can this thing not have a more custom workout for me'
Bang! It is now in custom workouts!
I feel like Tonal should just pay you for this.
Common Questions
Is Roni free?
Yes, completely free and open source. No credit card required. You bring your own Google Gemini API key (free from Google AI Studio) so the AI runs on your quota, not ours.
Is it safe to connect my Tonal account?
Yes. Your credentials are used once to obtain an access token and are never stored. The token is encrypted with AES-256-GCM. We only access workout history, strength scores, and movement data.
How does the AI coaching work?
The AI analyzes your training history, strength trends, and recovery patterns to build personalized programs. It applies progressive overload, periodization, and injury awareness — grounded in your actual data.
How is this different from Tonal's built-in programs?
Tonal's programs are pre-built for general audiences. Roni creates fully custom programs based on your data — your lifts, recovery, goals, and injuries. It adapts week to week as your performance changes.
