Accessibility Comments

AppleVis Editor Note: this app was submitted before Usability Ratings were introduced, so one has been chosen on the basis of the accessibility comments made by the original poster. If you have used this app, please post a comment to let us know if you agree with the Rating.

Original Comments: This app is accessible, though some users may find it to be counter-intuitive. To answer a call, users must double tap or split tap the line 1 button. If you get another call while you're already in a call you've answered, you must hit line 2. It's common sense but most people are expecting an answer button.

VoiceOver Performance

VoiceOver reads all page elements.

Button Labeling

One thing to note is that there's no way to review what you've dialed if using the dialpad. I learned that the hard way by calling a random person instead of someone I wanted to call.

I just discovered Whistle Phone and after some initial problems getting it to take the password, I called a friend in California and the connection sounded as good as my land line. This is on an iPod Touch 3RD Gen. I had to change the password to get it to work. Apparently you must have an 8 character password or use some capital letters. My first password didn't have either. You also have to split-tab or double tap on each digit of the phone number--no touch typing. I wrote the developer about that. Otherwise, a fine app.
