### 1/5 — A lot of fixes

*2025-03-20*

This game is trash one when you’re not even able to change the language how does this even make sense? Like, how can kids from America be able to understand this?

**Developer response:** 안녕하세요, Class123 서비스를 아껴주시어 감사드리며 갑작스레 무거운 소식을 전하게 되어 대단히 죄송합니다.
Class123을 지원하던 아마존 클라우드에서 MYSQL 5버전 지원을 종료하게 되면서 서비스를 이어갈 방도를 찾아보았으나 안타깝게도 2025년 3월 31일을 마지막으로 종료하게 되었습니다.
그동안 Class123 서비스를 이용해 주시어 감사 말씀드리며 문의 사항은 고객센터 class123@jtts.co.kr메일로 문의주시기 바랍니다.
감사합니다.

### 1/5 — I can’t create an account

*2024-07-28, version 1.2.4*

I’m trying to create an account but I can’t because it says I have to put my phone number and I did it like 20 times it says “please enter your mobile phone number in the correct format”, I did correctly but it’s saying the same again and again

### 1/5 — Doesn’t let me use it

*2024-02-29, version 1.2.4*

It keeps pausing and won’t let me click anything

### 1/5 — Needs Work..

*2023-05-22*

I was using the app and was not pressing the things o wanted it to press. I feel that you guys need to add more 𝔾𝕣𝕠𝕠𝕧𝕖𝕪𝕟𝕖𝕤𝕤 to the app. It’s SO simple and not fun at all for the kids.

### 5/5 — Class123

*2020-06-27*

Very good app             Rate: 10

### 4/5 — Good, but problem with behaviour editing.

*2020-01-17, version 1.1.4*

This app works really well, giving Wows and No-no’s. Attendance too. But whenever I try to save edited behaviour options, it won’t save. Please fix this! I’m losing my temper.

### 2/5 — It’s too complicated

*2018-10-27*

After downloading app, I instantly tried to find out how to use it. But it turns out that I can only add students’ name and ... that’s it. It seems that u guys(app developers) try to add so many functions, which are useless after all.

### 1/5 — App not working!

*2018-09-10, version 1.1.4*

Having successfully used the app all of last year, I can now no longer use it at all! It just says service is temporarily unavailable. What’s going on?

### 1/5 — Bad

*2018-05-23*

This is alful this doesn’t work at all for me I cannot even absent 2 students

### 5/5 — Good

*2016-12-29*

I heard about this app as an alternative to Dojo where kids can earn eggs. I love that idea! The only problem I have with this app is that I can't find a way to view which student has eggs and how many. This would be perfect if I could see that from my phone. I give my students a leader stick right now for every 10 Dojo points they get. This app would be better because sometimes a sneaky child will snag a stick from another child.  The eggs would be an easy way for me to track how many sticks they should each have.
