You mentioned several Apple devices so I assume this person has an iPhone. They will need to learn voiceover for iOS but there are a ton of YouTube videos in order to help them along the way. They can also have full control of their Apple TV and use voiceover on their Apple Watch as well. Here’s an introduction video from Apple regarding using voiceover.

I am 100% blind and I answered this question using just my iPhone and voiceover. The beauty of voiceover is how well it is baked into the ecosystem. You can do everything from find discover and playback audiobooks all the way to pay your credit card bills and even shop on Amazon. A great place to start his YouTube because of its accessibility features and also it’s content with the ability to learn more about voiceover and have a lot of practice with it within the app. There’s even an app specifically for the blind like be my eyes which will allow you to call somebody using the camera and they can assist you in that way with your phone. Or Seeing AI which will read most things including nutrition labels and signs plastic and read documents or letters it can also read products by scanning barcodes it can also tell you what type of money you have in your hands it can also tell you what color something is and it can also tell you if there’s light in a room in case you forgot to turn on or off the light, Plus this is all done locally on your phone you don’t need any Internet data and nothing is ever sent out from your phone.

We are all here to help you if you need the help just ask. The technology part of all this is actually easy once they learn voiceover they can actually start using a Mac as well.

Not sure if this helps, but if they are able to learn how to use their phone and have a good set of headphones, I've been really wanting to share the videos I make with the blind communities. I've put a lot of work into creating high quality binaural walking videos which can stand on their own without the video.

For example:

A walk through the forest: $1

A walk through a park: $1

A Chinese music event: $1

Walking by a lake in a rainstorm: $1

My goal is to provide people with peace in difficult times.

Good organization in the house, so everything is almost at the same place every time. e.g. inside the fridge for me one shelf is for fruits, one for vegetables. Simplify furniture, don't leave tables in the middle of the room.

Don't put vases and other breakable items in the way or on top of tables. Instead of glasses (they are transparent) use cups. Get rid of everything where the person can trip over, like random rugs on the floor. Close every door (cupboard, dishwasher) every time.

Create contrast whenever possible. Use a white plate on a dark tabletop when eating. Lots of lights everywhere that is easy to control how much they need it. White doors, but dark doorknobs. Bright walls and dark light switches.

Don't use glass inside the house if possible, like doors or furniture that have glass doors or shelves. Hard to see and dangerous if it breaks.

With any electronic device there is a high contrast theme that can be activated. Increase font size - by a lot.

Reading - kindle is a good start, the fonts can be increased a lot and it has a backlight, but still way more comfortable on the eyes than a tablet. Audiobooks are actually way better and can be listened to on big speakers, tabletop speakers, the phones speaker or headphones. You can use Audible, but also blind people have access to free audiobooks at some local organization for the blind. Or learn Braille. There are many options.

Learn voiceover/talkback for phone usage, also computers have their speech applications. If the person is less tech-minded just buy a talking clock as a start. And a radio. And with a few exceptions (like the smartphone's touchscreen) physical buttons are way better than the modern touch sensitive ones (e.g. even microwaves, lamps and other household items come with those nowadays).

Ask for help when there is a possibility to get some. Running race? Get a guide. Airport? Get assistance.

Can't ride a bicycle anymore? Try a tandem bike.

Experiment. Try out a cane if that helps. Or a flashlight. Find a hobby that is enjoyable - play chess, read, take walks in nature, have a pet, etc. Go try things until you figure out a way it works.

What helped me wasn't any kind of widget or gadget beyond just a stick to hit things with to see if they're there. Try to take my cane from me and we will argue (some airline cabin crew have tried this but it's OK because most of them are back on solid food now).

I think what helps is the realisation that you don't have to like it, you just have to find a way to deal with it, which isn't the same thing. What's overwhelming is the feeling that you somehow have to end up having it feel empowering and wonderful like all the people on youtube. You don't, at least not all the time. It's not like that all the time for anyone. That's not reality for most people. But you can deal with it.

Which brings me back to the whole cane thing. Get mobile, go places, learn how to organise trips and events and visit places. The knowledge you can do that, that you can still do that in an approximately normal manner, is huge. Yes, I know that feels impossible right now, but it is learnable, it is a system of doing things, it is just problem solving.

You probably can't learn to love every second of sight loss, but problem solving you definitely can learn.

Wife is in the same space with the vision. Audiobooks. Check your library or an app called libby. It could save you some money in the long run. Audio description on movies they are a pretty big thing in our lives they can be found on most newer movies in the subtitles menu. From our experience dont wait on your doctor's our kept pushing off the white cane and she would have extreme anxiety about going out. We found some helpful you tube videos about canes and bought one marshmallow tip and its been a dramatic improvement for her confidence and anxiety. Also if the phone thing works out a decent set of wireless earbuds with microphone capabilities can be helpful for them to get some privacy while web surfing or scrolling thru Facebook and it will make it easier for you to remain close with out haveing to listen to their phone. Very new to this but every one here has been so helpful.

Others have already told you about VoiceOver, and that's definitely where to start. I wanted to offer a couple other thoughts, though.

First, you can use Siri for a good amount. Checking the time, the weather, replying to messages, and so on are all doable. On Apple TV, you can issue commands like "watch [movie name] on [service]". If you've signed into the service’s app, like Netflix or Disney Plus, this will work. You can also just say "watch [movie]" and Siri can figure out where the movie is.

Finally, you should look into an Amazon Echo. I only say an Echo instead of a HomePod because Alexa is more forgiving of phrasing, and because it works with Audible. If you buy a book on Audible, you can have the Echo play it back for you just by saying "Alexa, read [book name]". Of course, Alexa will answer basic questions about the time, weather, and the like just as Siri will.

Smartphone/I phone with talkback: android and voiceover: Apple. These both software can read the phone screen out loud. Not only the use of these would solve the above written problems but also unlock many positive possibilities!

Audible slaps HARD I use it all the time bc blind girl vibes. I recommend getting these tactile bumpy stickers to put on things so they know what they are or where to put it (for example a dryer and putting it to a specific way) ALSO I recommend looking into a guide dog, it’s like one of the best things to happen to me bc I’m like now I can have a cute dog instead of an ugly cane lmaooo

If they can still see well enough to read large print, they can use their phone's camera to see better.

I'm legally blind without contacts, and I have my camera set to the shortcut of double pressing my power button (I don't know the apple equivalent). By zooming in on my phone, I can read signs, look for items, etc.

I also have the app "WeZoom" (again, I'm not sure if it's on Apple or the equivalent) but it also uses the camera to zoom, but you can also freeze the image, change the contrast, etc.

Not sure if these would help but here's what helped me when I was low vision...

\-Phone accessibility: Large font on phone, magnification/zoom feature, dark mode (if they struggle with contrast)

I also tried using a Kindle for a bit but the UI is really small, so I struggled. Maybe get them a tablet (Samsung or Apple, whichever they prefer), because the larger screen makes it easier to see. Oh, and the phone accessibility settings are the same for the computer, just with a large cursor too. I would also suggest audiobooks for reading, I wish I discovered them when I was low vision. maybe

Check out the Blind Shell 2 phone. I posted about it a couple of weeks ago.

There’s applevis.com for apple devices.

Blind people could use computers as well but perhaps Learning the phone might be easier.
