Beta Phase is coming.
The Android beta is being hand-prepared for a small cohort of 80 builds. Register your interest now and you'll be first in line when test builds go out.
REQUEST BETA TEST BUILDIt is not a fitness tracker. It is not a navigation app. It is the digital twin of your machine — recording vitals, tracking rides, watching over what you love.
Every build is personal. Your interface is configured for your machine, your riding style, your preferences. No two builds are identical.
Sentinel is invite-only, intentionally small, and delivered by hand. It will never be on the App Store.
Five systems. Running on your phone. Working while you ride.
The Beta Phase opens after the rider survey closes. Requests are handled on their own page — just your name, email, and machine. No generic signup funnel.
