Roll Mobility vs SentryChair

Know before you go. Empower others as you roll. Roll Mobility makes it easier for wheelchair users, caregivers, and allies to navigate public spaces with confidence. Whether you’re going to a coffee shop, hotel, campus, or event venue, Roll helps you discover how accessible it really is before you get there. We believe accessibility shouldn't be hidden or hard to find.

SentryChair turns a wheelchair and its companion sensor hub into a connected safety monitor — for the person who uses the chair and the people who care about them. Pair the app with your SentryChair hub over Bluetooth (no internet required for the connection) and see live readings from the chair right on your phone: • Obstacle detection — a time-of-flight sensor measures how close objects are in front of the chair, and the hub sounds an audible warning when something gets too close. • Seat occupancy — a pressure sensor shows whether the chair is currently occupied. • Live location — the chair's position is shown on a full map, so you always know where it is. • Emergency SOS — one tap opens your phone's dialer pre-filled with emergency services. • At-a-glance dashboard — connection status, obstacle distance, seat occupancy, and battery, all in one place. SentryChair is designed to be simple, calm, and dependable — giving wheelchair users more independence and giving caregivers peace of mind. Sign in with a secure account to get started. Note: SentryChair works together with a SentryChair sensor hub attached to the wheelchair.
