Sency (SMKit)

Directory entry · facts from The Best AI Workout & Motion-Tracking APIs (2026), last verified October 18, 2026

Sency publishes per-user plans, but on two pages that disagree about whether its first active users are free or covered by a paid monthly fee, and sign-up runs through a contact form, so confirm the terms in writing. Models download from Sency's server at configuration. Before launch: Sign-up runs through a contact form that leads to a call, and Sency's Terms of Use put commercial or production use under a separate paid service agreement.
