The most recent issue of "Talking Book Topics" (July/August, 2016) mentions, in the "In Brief" column, an app called SeeLight and SeeLight Blind. The "Blind" version of the app is intended to assist with the location of traffic signals and other information to be used by vision-impaired pedestrians. I was curious, so I downloaded and installed the app from the Apple Store on my iPhone 6 Plus. After opening it, I discovered the text on the screen is in Cyrillic. Pressing the "right arrow" button visible on the screen resulted in Russian speech, apparently providing information about using the app.
There is a warning in a review of the app on the Apple Store that the app is in Russian. The app also has not been updated since July 1, 2015.
I think it strange that "Talking Book Topics" would mention an app that appears to default to Russian when launched. Stranger still is lack of information in the details about the app on the Apple Store regarding the default language, or any suggestions to change the language as appropriate for local users.
I deleted the app from my phone, so I hope no harm done.
I wonder if it is appropriate to ask Apple about this? I did email NLS concerning their discussion of the app in the latest issue of their magazine.
