Nintendo’s first mobile app, Miitomo has more than 10 million unique users. Nintendo made the announcement today. In the United States, the “free-to-start social experience” quickly reached the top spot on multiple app stores for different devices.

“With Miitomo, Nintendo takes its first step into the world of smart devices,” said Scott Moffitt, Nintendo of America’s Executive Vice President of Sales & Marketing at the app’s launch. “Miitomo brings the special Nintendo charm and polish that people around the world love to an entirely new format and audience.”

In Miitomo, you create a personalized Mii and answer questions on a variety of topics like “what did you do last weekend?” or “what’s your favorite food?” Then, when players are offline, everyone’s Miis will visit other Mii’s homes and have a conversation. When you log back in, your Mii will tell you what they learned by talking to other Miis. You can see other Miis visit your home while logged in and can answer some of their questions directly.

Besides the conversational aspect, you can also buy clothes for your Mii, and play a pachinko-style mini game.

In a Pixelkin feature shortly after the app’s release, contributor Courtney Holmes said she thought Miitomo’s user interface to be clunky. She also said that she started to get bored after a few days of play.

Nintendo will be celebrating the 10 million user mark by by offering a in-game promotion from April 29 to May 8. Nintendo hasn’t announced any details on the promotion.
