I just dey come here ooo.
The most important three apps for now for me are discord, Whatsapp and tiktok, all are used for money making, lol

Ever since I joined hive, discord is a app I log in daily, no day goes without coming to discord. Then Whatspp, though it's not only for business, I can't with friends and family but then I post my works,it's my first means of product advertisement. Then tiktok is for advertising of my products as well.
These three apps brings money in, that's why they are the top three, who don't like money, lol.
