The original iPhone app is still available in the App Store so you may have to scroll to find the correct one, or you can download it from iOS app link above.
Here is the symbol you are looking for:
There is no text on the icon for this app. The previous app had the word “Mish” on it.
If you had the original iPhone app installed, I recommended deleting it and loading the new app. This link will explain How to Delete Apps From iPhone 5 or iPod Touch.
The new app was developed by Stephen Asherson and Rachel Strate at 2Bits, and it’s free. Feel free to contact them with any app queries.
