Roll Mobility shows you what a place is like before you get there. Is there a step at the entrance? Does the restroom fit a wheelchair? How loud, bright and crowded does it get? The answers come from people who get around on wheels, with a cane, with a stroller or with sensory needs. They know what to look for, so the details in their reviews are the ones you need. THE MAP See the places around you, with pins colored by restroom rating. Filter by sound, light, smell and crowd levels, by rating, or by who added the review. Tap a pin for the place's accessibility features, photos and reviews. WRITE A REVIEW A review has three short sections: Venue, Restroom and Sensory. Each one takes a few minutes and asks what the next visitor will want to know. Confirm the features you saw, like automatic doors, accessible parking or an adult changing station, and add photos. EARN POINTS Reviews, photos, videos and snapshots all earn points. Move up from New to Reputable, Established and Expert, and see where you rank worldwide. SNAPSHOTS Pin a quick photo or video to the map to show a ramp, a broken elevator or a blocked sidewalk. THE FEED Reviews, posts and news from people near you and people you follow. Follow anyone whose needs are like yours, and join groups for your city or for the things you care about. BUILT FOR MORE PEOPLE Roll Mobility is available in 16 languages. Map pins have a color-blind friendly option. Browse the map without an account, and sign in with Apple, Google, email or a phone number when you want to post. If a place has no reviews yet, you can write the first one.

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. For questions and support please email hcheng27@cranbrook.edu

Verdict
The clearest difference is review sentiment: SentryChair at 100% against Roll Mobility's 44%. SentryChair also leads on rating (5.0 vs 4.3) and iOS requirement (15.0 vs 18.0). Roll Mobility's advantage is update cadence (weekly vs every 3 months) and ratings volume (123 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
