In the usual debates that rage in smart phone accessibility circles, two platforms dominate the discussion, apples iOS and Googles android.
To be sure, they both have their advantages and disadvantages but for me, iOS stands head and shoulders above any other platforms for visually impaired people who use screen readers, voice-over is one of the greatest feats of engineering ever, in my view.
But when it comes to tablets, things are more complicated.
I'm referring to Amazon voice view, the screen reader used on Amazon Kindle Fire tablets, Voice view has many of the same gestures as iPadOS including the two finger magic tap gesture to pause and play media and start and stop dictation, though it doesn't have a Rota gesture instead using a more circular jesture to access navigation by granularity.
And there are certain advantages to having an Amazon device, you're not locked into Apple's ecosystem, you can use USB sticks and regular chargers, and Amazon tablet are much cheaper.
Having said that, there are many disadvantages:
Amazonvoice view doesn't get updated nearly as often as iPadOS, and it doesn't support Braille screen input, though you can use an external Braille keyboard.
Beyond that, Amazons selection of apps is quite lacking compare to the other platforms.
So for now, iPadOS remains the best software for visually impaired people who need screen readers, but who knows, that could change in the future if Amazon steps up its game.
