Accessibility Comments

There are some minor issues for VoiceOver users, but all parts of the app do appear to be accessible.

There is an unlabelled button on the main screen that loads the information about moon phase, day length and your coordinates. This seems to be displayed in some form of overlay, and it can take some tapping to actually get focus on this information. Until you do, VoiceOver will keep announcing items from the main display.

This is the only real issue for VoiceOver users. The only other challenge is to see how long it takes you to realize that the two separate numbers located near the top of the main display are the sunrise and sunset times.

VoiceOver Performance

VoiceOver reads all page elements.

Button Labeling

There are some minor accessibility issues with this app, but they are easy to deal with.

Apparently this app is no longer free because the iTunes page for the app says free for today only. I don't remember now what the price is but I think it was $1.99. Maybe it used to be free, but I just looked into this app for the first time today so I wouldn't know.

Hello Julie, Thanks for pointing that out to us. I have made the change to being a Paid app. I just checked on it. It appears to have gone back and forth of being $0.99 and to being Free fequently this year but it is indeed a Paid app. Thanks!
