Before make a sticker app, Which language will you use?

In Korea, SMS is not used frequently.

Other messenger apps are mainly used.

I was worried about which country to target before I made the sticker app.
- How many people use the iPhone in that country?
- How many people use SMS (Imessage) more often than Messenger app?
- How many people use stickers frequently while using SMS?

So I do not use Hangul in my sticker app.

I mainly use English.

Use only pictures that can express their meanings without writing.

So, most of the countries that bought my sticker app are Europe and America.

If you plan to make a sticker app, you have to worry about which country you are targeting.
