Accessibility Comments

For the most part, the information provided in this app is very accessible and easy to follow.

The month views can be a little confusing at first, but once you familiarize yourself with the layout and ordering of the data, it is possible to translate this into something meaningful.

The Overview, Sun and Moon tabs all have information spread across multiple pages. A 3-fingered swipe to the left or right should move you through these.

Many of the pages have a previous and next button beside the main date indicator. Unfortunately this is not recognized or usable with VoiceOver. Thankfully, there is a dedicated Date tab that can be used to switch dates, and this works fine with VoiceOver.

On the pages which show you the current state of the sun or moon, double-tapping on the time will bring up a selector that allows you to change the time.

I've yet to encounter any other significant issues.

VoiceOver Performance

VoiceOver reads most page elements.

Button Labeling

Most buttons are clearly labeled.


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