Tempo is a hardware-first fitness product: a $495 smart mirror with built-in AI form tracking, guided workouts, and rep counting via computer vision. The subscription adds $39/month. It is genuinely impressive technology — if you train at home, have floor space, and want live AI feedback on your movement. TrainSMS is infrastructure-free by design. No device, no mirror, no $495 upfront. Your program arrives by text each morning, you do the workout wherever you are, and you reply DONE when finished. The core difference is where you train and how you want coaching delivered. Tempo is built for a fixed home setup with hardware feedback. TrainSMS is built for anywhere — home gym, commercial gym, hotel, garage — with your phone as the only interface.

No. TrainSMS works entirely through SMS — your phone receives the workout, you do it wherever you are, and you reply DONE when finished. No mirror, no device, no app download.
Yes. During onboarding you specify your equipment — full home gym, dumbbells only, barbells and rack, bodyweight only. The AI builds a program around what you have. It works equally well for a commercial gym or a garage setup.
Yes. You keep the Tempo hardware if you want it. Cancel the Tempo subscription and start a TrainSMS trial. Enter your current lift baselines and goals during onboarding — the AI picks up your training from there.
Not real-time rep feedback like Tempo's computer vision. The AI responds to your messages — text that a movement felt off and it will cue adjustments or suggest a swap. Live visual feedback during a set requires hardware.
TrainSMS and Tempo serve different functions — Tempo guides individual sessions, TrainSMS handles periodized program design and delivery. Some users run both: Tempo for guided execution, TrainSMS for macro programming.
