If your main concern is scanning a road or room for obstacles or items of interest, Sullivan+ is a reliable app. Its AI software works well and reasonably fast in identifying objects, describing scenes, and reading text.
It is free and available on both Android and iOS. I tested it and it works just fine.
There’s a little tutorial to get you started but, other than that, it is quite obvious on how it operates.
The extra tools on offer make it even more interesting. For example, you can scan for faces, check a car’s colour, video call a contact, and read PDF files.
It can take a few tries to get accurate results, but Sullivan+ is definitely an app worth getting used to.
