I'm currently using Blindsquare, And so far it has worked pretty well for me. Sure, sometimes the markers around the city might be slightly wrong, however you can easily update the markers for your device, when you've found the spot you were looking for. I've had some mobility training with my teacher, who is completely blind, and he says Blindsquare is one of the best things he has experienced during his lifetime. He was born in the 70.s, so I think he knows what he's talking about.

I think it depends how you use how good you are at directions and mind mapping. I like it actually. I don’t need a lot of directions if I do, I specific ask of a real human. I use it for address,es bus routes, and such. It’s a useful app though.

BlindSquare only tells you the points of interest and street names around you as well as the direction and distance to your target location, and relies on third-party apps like Apple and Google Maps to do the turn by turn navigation. It is still a lot more helpful than just navigating using Apple Maps. With a recent iPhone (either 8 or X) the precision of its markers is probably much higher since from what I heard the new iPhones use the Galileo positioning system which offers location information with a precision of 1m whereas GPS offers a precision of 5m.

I tried out the Seeing Eye GPS app for iOS in the fall. It was not for me. It seemed to have some cool features but also drained the battery quickly.

It is not an iOS app but I am looking forward to getting a Victor Trek from HumanWare in the future. I like the combination of GPS and reader in one. Though I have not tried one yet.
