Miitomo launched in the US on March 31, and after nearly two weeks of being available on both iOS and Android devices, it appears Nintendo officially has a hit on its hands as the app is currently being enjoyed by four million active users and is earning $40,000 in daily revenue.

According to a Survey Monkey report, Miitomo achieved over 2.6 million downloads during its launch week and was downloaded an average of 370,000 times per day. On average, a user checks into Miitomo two to three times per day with a total of 7-8 minutes spent within the app itself.

What we’re curious to see is if Miitomo has longevity as its retention is a big question mark right now. Sure - we’re all enjoying learning about our friends and family by answering various questions, purchasing new clothes, and playing silly mini-games to earn even more clothing options. But whether or not this will be a new mobile social network that will take the world by storm is yet to be seen. In the meantime, what did you do last weekend?
