The ThruDoor app is a pedestrian mobility service to ensure freedom of movement for all. It enables its user to receive mobility assistance from door to door, or within a building to a destination. Users can call a certified, vetted, and trained companion to their specific location. Companions will be filtered based location, availability, and on user-selected needs that include language and the ability to provide assistance or accommodate other mobility factors such as a wheelchair. Whether indoor or outdoor, the app helps companions find the user through location services, wayfinding, and direct audio and visual communication. ThruDoor is not approved as a medical device.
