Does anyone know of a way that I can preserve my streak longer than a day?
I will be going to a place where there's no Wifi and I'll be there for 4-5 days. I really don't want to lose my streak.
u could give your password to your account to somebody you trust and put your goal to 1xp daily, and tell them to one lesson for you, or just strengthen your skills for you...
Is mobile phone contact possible?
Maybe you can use a smartphone and LTE/4G with an internet bundle?
Set your daily goal to a maximum of 10 XP.
There's no easy way. Sorry. It's just like divisibility rules of 7: they exist, but aren't convenient. But great streak! 100 is huge!
