It is only for team member of SeoDangGol 17th who are using Android phone, and you should know that there is no i-phone Version cause Kimyoon don't like i-phone even though he respect Steve.
This is very raw version of the application so it might have various problem. If you find any error or and suggestion, please contact Kimyoon ASAP and give him some Advise then you can eat some snacks for free.
I love you
God loves you
Thank you very much
