The emoji must comply all the style and particular things of your pet but also it must be a real emoji that express a shareable emotion. A simple emoji art usually takes around 7-9 days. A emoji pack around 15. The Emoji sticker app needs basic development and set the App Store presence, so it usually takes 30 days. If you have chosen the Emoji Keyboard app, your app will be published in the App Store & Google Play in 60 days.
