Do I need all three devices to use Obi?+
No. Obi works with any single device, and the app automatically adapts its interface to whatever is connected. Fusion improves with more devices, but one is enough to start.
Does the app work without an internet connection?+
Voice coaching and core sensing run on-device. History sync and program updates need a connection, but a session in progress will never stop for lack of Wi-Fi.
What phones and tablets are supported?+
iOS 16+ and Android 11+ with Bluetooth Low Energy. Web Bluetooth in Chrome is also supported on desktop and Chromebook.
Can a physiotherapy clinic use consumer devices with Obi Pro?+
Obi Pro requires the clinical-grade sampling tier of hardware for outcome reporting accuracy, but the app and data model are shared across tiers.
How is my data used?+
Movement data is yours. It is used to power your coaching and progress tracking, and is never sold. See our Privacy page for full detail.
What’s included in the Founder’s Bundle?+
One Obi Mat, one Obi Pulse, and two Obi Motion nodes, plus a full year of Obi Pro included at no extra cost for early backers.
