Feel a route change, then see how RollSense remembers it

Smooth ground asks almost nothing.

Your chair rolls with little interruption. For a moment, a route line feels like enough.

This is the personal baseline RollSense is being built to learn from your rides.

Smooth surface. Low vibration.

Signal locked · Smooth surface

One simple action. A route you can remember.

RollSense is being designed to learn from the sensors already inside your phone. No stopping to photograph every crack. No pinning every rough curb by hand.

  1. Mount

    Secure your phone to your wheelchair frame, armrest, or another firm mount.

  2. Ride

    Start a ride and travel normally. The goal is to record wheelchair and road movement—not phone movement in a loose pocket.

  3. Learn

    Finish the ride, share a quick rating, and build a personal memory of smooth, rough, and difficult segments.

Secure mounting matters.

A phone held in your hand or moving inside a bag can produce noisy, misleading signals. RollSense needs to feel the chair and the street together.

Surface change · Small irregularities

Step-free doesn’t tell the whole story.

Two routes can both be step-free and still feel completely different from a wheelchair. One may be shorter but exhausting. Another may take two more minutes and leave you with more energy.

RollSense is being built around a better question: How suitable and comfortable is this route for you?

Your map first. A shared map when you choose.

RollSense should be useful before a city has thousands of contributors. Your own rides can build personal route memory from day one.

Later, eligible ride observations could improve a shared route-quality layer—only with your explicit consent. Community contribution is planned to be opt-in, privacy-aware, and separated from public identity.

Private ride history by default Community contribution by choice No public home or work endpoints
Surface change · Strong impacts

A route can reveal a life. Privacy cannot be an afterthought.

Location and mobility data may reveal home, work, school, medical visits, and daily routines. RollSense is being designed around that reality.

Consent
Clear permission before ride collection or community contribution.
Control
Private ride history by default, with deletion and sharing choices.
Minimization
Collect what the ride needs and avoid retaining raw data without purpose.
Separation
Keep account identity apart from public map contributions.
Ride complete · Route remembered

Help RollSense learn from real rides.

The first closed beta is being prepared for iOS and Android. Testers will take a few short rides with a securely mounted phone and share quick feedback after each one.

Founding testers who complete the early testing program will receive RollSense Premium for life. The final Premium feature set is still being defined; the reward is for meaningful participation, never positive reviews.
