Free navigation apps for the blind

Hello,
Thanks everyone for the suggestions.
Jenna, I never did get good with cardinal directions. I have been blind my whole life, but o&M was never my strong point. My family always lived out in the country, and was never able to get much in the way of practice with my family, just the few hours a week or every two weeks from the traveling instructors while in public school, and a bit more when at the school for the blind, but I just never got good. I lived in a bigger city for a while, and really enjoyed being able to use Uber for getting out and about, but once again find myself in a small town, and we don’t even have that here, so I don’t get out much unless I have a ride to wherever I need to go. I’m slowly trying to change that. Even if it is only to take my dog out for walks. And hoping some of these apps can help. I will try and get my hands on some bone conduction headphones. I do have the AirPods Pro, and love them, but completely understand what you mean about not walking around with them in. I mean inside, sure, but not outside. No way.

Wow, Soundscape is awesome. I was able to take my dog out, and walk up and down my street from intersection to intersection several times. Some of the streets around mine have pretty bad ditches along them, so not quite ready to venture further than that on my own just yet, but it was pretty awesome just to be able to get out, just my dog and I, and know when I was approaching each intersection. This dog is not an officially school trained guide dog, but I’m working on self training her, and so far she is doing really well, and this app has given me the confidence to get out and about with her so we can practice. I have gotten to the point where I do feel more confident walking with her, and at a higher speed, than what I feel while walking with the cane, and I have been a cane user my whole life. I know just going up and down the street might not seem like a big deal to most, but that’s a lot more than I’ve been able to do by myself in this small town since I’ve been here. When I was in a big city, I used Uber, but I could also get to a bus stop and then from the next stop to where I was wanting to go, whether that was the mall, gym, or whatever, so I was a lot more active. But, I moved back here to be closer to family, though I do live alone. And since I’ve been here, since 2015, I get out whenever I go to church, or go shopping with family or a neighbor. And in summer when the weather is nice, I have a neighbor who will go on walks with me, but other than that, I never had the freedom to just take off and go. It’s kinda funny. It is nothing for me to hop on a plane and fly across the country, or even international. I’ve been to Mexico, Ecuador, and Puerto Rico multiple times. Yet, I can’t even make it around my block alone. It’s the orientation in orientation and mobility that messes me up. But this app I think is just enough of a confidence booster for me to get out there and do more exploring.
One question about it though. Will it keep working when the screen is locked? I didn’t try locking it, since I just wasn’t sure.
