When you send an emoji from your Android device to someone that uses an iPhone, they don't see the same smiley that you do. And while there is a cross-platform standard for emojis, these don't work the same way as unicode-based smilies or dongers, so not every operating system displays these little guys the same way.
This can lead to confusion, or even an awkward break in communication. Perhaps you picked out the perfect emoji to suit your sentiment, but when the recipient views it, your message comes across in an entirely different light—a simple misemojication.
So developer Paul Hollinsky created a nifty little app that will let you see exactly what your emojis will look like when viewed on an iPhone. The app is incredibly simple to use, too, so it should take all of the guesswork out of picking the proper emojis.
Hollinsky's app is called Emojily, and it's available on the Google Play Store for free. Search it by name to get the app installed, or head directly to the install page here.
The app has a simple and intuitive interface. Just use the text field to enter any emojis that you'd like to send to an iOS user, and they will be displayed exactly as they would on an iPhone.
Not all keyboards have a dedicated emoji button, so you may not be able to enter your emojis into this field directly. If that's the case, simply open your favorite messaging app and queue up a message that contains some emojis.
From here, just copy the message, then head back to the Emojily app and paste the contents into the input field. You'll see your message exactly as it would be shown on an iPhone.
As an aside, note that Android will not allow you to copy a message that contains only emojis, so you'll have to type at least one character if you use this second method.
