Interface of simeji

How to set the app interface to english language? I like simeji been using it for 5 years now in my samsung phone and now i’m change to iphone but its kinda complicated simeji in iphone with the app interface and with the keyboard layout especially when you want to flick some of the sign in alphabet like ex , . ? ! You can barely see it visible its so small especially when u used your own picture theme. You can even see it. Will give it 3 star for now. Please reply to this and give advice and solution. Thanks.

Good app but...


This app is really good! However, I do wish that there was an option for just English. I have a hard time understanding it because I only know some hiragana. That is the only reason I rated it 4 out of 5 stars! Great app. I would definitely recommend. And yes a may have used the internet to translate this.

Nearly Ripped My Hair Out

The app looks like so much fun, seeing the cute animated critters and emojis really makes it seem cool, but I cannot understand a lick of it. In the description of this app, it says there is an English option but how does one obtain that? How does one actually GET the app in English? Seriously, I have been searching for 2 hours now and haven’t found an answer. Is it cause I am on IOS? Or am I doing something wrong? Please, put a thing at the beginning to change the language settings in the app. Thank you.
