Nintendo's smartphone offerings haven't reached a "satisfactory profit point yet," according to outgoing president Tatsumi Kimishima.

The company has been attempting to make headway on mobile since the launch of its debut (and now defunct) smartphone app Miitomo in March 2016.

In the two years since, the Japanese console maker has brought a number of key franchises to mobile with the launch of titles like Super Mario Run, Fire Emblem Heroes, and Animal Crossing: Pocket Camp.

Looking from the outside in, you'd be forgiven for thinking that current roster was performing admirably. Super Mario Run, for instance, currently boasts around 20 million monthly active users, while Fire Emblem Heroes reportedly earned $300 million during its first year.

Nintendo, however, is more subdued in its praise, and although the company acknowledges its lineup has delivered the goods in terms of raising consumer awareness, it claims they've yet to turn a profit that meets expectations.

"We will continue the services for existing applications while also releasing new applications in order to increase Nintendo’s presence in the smart device business," commented Kimishima during a recent financial briefing.

"The efforts we have made to date have yielded certain responses to our goal of expanding the number of people who have access to Nintendo IP. Even so, we have not reached a satisfactory profit point yet, so our goal is to further expand the scale of this business to develop it into one of the pillars of revenue."
