Try Emojily. >You input a string of text and emoji, and it will show you what an iOS user would see.
Because whatsapp insists on not being consistent with the rest of Android.

Try the Google Play app store. Oh my god are the reviews on there annoying. This is my app, Emojily and all it does is takes the emojis that you type into the app, and displays the iOS equivalent.
The "helpfulness" view doesn't give a real good view of this, but you wouldn't believe the amount of 1 star reviews I get saying "yeah but it doesn't change the emojis in snapchat, 1 star" or "how do I make this app a keyboard? 1 star" or even "I don't understand how this app works/why anyone would want it, 1 star"
