What’s New Version 2.6.3
- Faster onboarding — fixed a rare issue where the "Analyzing your last 30 days" screen could get stuck. New members now move through the intro smoothly.
- Instant home screen — your weekly schedule now loads from a local cache first, so your classes appear the moment you open the app.
- More reliable bookings — resolved issues that occasionally blocked class reservations from going through.
- Stability and performance improvements across the app.
Description
Plan smarter. Train consistently. Let KYN AI handle your week.
KYN AI builds a personalized weekly fitness plan around your goals, your schedule, and the way you actually train — then books it for you. No rigid programs. No guessing what's next.
Requires an active Sweat & Tonic membership.
AUTO-BOOK YOUR WEEK
Set it once and KYN AI lines up a full week of classes built from your Go-To favorites, shows you the plan, and books the whole thing automatically. Review it, toggle any class, or skip any week — you're always in control.
YOUR FITNESS SNAPSHOT
When you join, KYN AI analyzes your recent training history across three pillars:
• SWEAT — your workout patterns, class mix, and training load
• RECOVER — your recovery balance and rest habits
• CONNECT — your studio engagement and consistency
Your snapshot refreshes regularly, so your plan always reflects the real you.
SMART CLASS SEARCH
Find classes the way you think about them. Type natural queries like "yoga on Friday morning" or "something after 5pm on weekends" and get instant, accurate results. Stack filters by time of day, class type, instructor, studio, and location to find exactly what you want.
SEE WHAT'S TRENDING
Discover the classes filling up fastest at each location and book — or join the waitlist — in a single tap, right from your home screen.
GO-TO CLASSES
Mark the classes you never want to miss. KYN AI prioritizes them every time it builds your week, so your favorites are always in the plan.
PICK YOUR SPOT
Browse real studio layouts and choose your preferred spot for every class format. See live spot availability while you book, so you always train where you're most comfortable.
WEEKLY CHECK-IN
Each week, KYN AI walks you through a quick, structured review:
• Reflect on last week across all three pillars
• Review and adjust your upcoming bookings
• Plan the week ahead — around your real calendar
Connect your Google Calendar so your plan works around meetings, travel, and life.
POST-CLASS FEEDBACK
After each class, rate your effort and share what worked. Your feedback directly shapes future recommendations — the more you share, the sharper your plan gets.
ADAPTIVE GUIDANCE
As you train and build consistency, KYN AI adjusts your future weeks to match your real behavior — helping you stay on track without overtraining or burning out.
INSTRUCTOR PROFILES
Explore instructor bios and social links to find the coaches who match your style.
WHO IT'S FOR
• Anyone who wants a personalized, structured fitness week
• Studio members who want their week planned and booked for them
• People returning to training after a break
• Anyone seeking the right balance of effort and recovery
Start training with clarity. KYN AI helps you plan smarter, stay consistent, and build a routine that works with your life — not against it.
Requires an active Sweat & Tonic membership. KYN AI is your companion app for planning and booking Sweat & Tonic classes.
