To modify which information is spoken, find the Filter Announcements button in the top row of buttons on the main screen and double-tap it to open the Filter Announcements screen. The bottom half of this screen lists all of the place categories available on Foursquare. By default all of them are active. Double-tap the Deselect All button in the bottom right of the screen. Now find the Shops & Service category and activate it by double-tapping. Subsequently you can close the Filter Announcements screen by double-tapping the Back button or performing the scrub gesture. Now that you have deactivated all of the other categories, BlindSquare will be able to read out more shops to you as you are on your way, because it does not receive information about cafés, sights, doctors’ offices, etc. When you have finished shopping, you might want to have a snack. You can now go to the Filter Announcements screen again, locate the Shops & Service category and deselect it by double-tapping. If you select the Food category now, BlindSquare will only announce restaurants, cafés, etc. as you walk. If all of the Foursquare categories had been selected, it would not be able to read out all of the listings in the Food category.

If you want to check which BlindSquare categories are active, just touch the Filter Announcements button. VoiceOver will announce all of the categories you may have deselected. To revert to the default setting and activate all of the categories, open the Filter Announcements screen and double-tap the Select All button in the bottom left of the screen.
