How it works
How 3S works.
Three steps from QR scan to the perfect shake — calibrated to you, not to the average.
The flow
The 3-step flow
Scan.
Scan the QR on the machine. A lightweight web app opens instantly. No download, no account required for your first try.
Tell us about you.
Four quick taps: weight, goal (cut / maintain / bulk), workout type, dietary restrictions. The whole thing takes about 30 seconds.
Sip.
The machine pours your personalized formula in 25 seconds. Pay with Apple Pay, Google Pay, or your saved 3S Pass.
The difference
What makes a 3S shake different
Trainer portal preview
For personal trainers
Your protocols, automated.
Build per-client formulas inside the trainer portal — protein dose, base, add-ons, training-day variants. Push it once and every machine in the network knows what your athlete drinks.
Earn a commission on every shake one of your athletes pours, anywhere in the network. The portal tracks attribution automatically — no invoicing, no chasing.
See real-time adherence: who's pouring, who's slipping, who needs a nudge. Coaching outside the gym, finally backed by data.
