The figure, though undoubtedly a milestone, has no direct bearing on the console's performance at retail, however, where it's believed to be struggling.
The NPD Group described US sales in its launch month as "relatively light" - a claim that Ouya founder Julie Uhrman challenged.
"Nobody thinks much about NPD numbers," replied Uhrman. "We all know they miss critical data including reporting from digital retailers or company sites."
Eye on Ouya
Ouya's creators have had bigger hurdles to overcome than supposedly slow launch sales, however, making today's declaration of developer support a notable one.
We've hit 25,000 registered developers, closing on 500 apps http://t.co/6cFQFmpWce Thanks u to everyone who believed! :)

Ouya upset a portion of its support earlier this summer when controversy surrounding the firm's Free the Games fund reached a boiling point after it became clear that two games were attempting to take advantage of the fund.
Some developers pulled their games in response to Ouya's handling of the situation, but others rallied to Ouya's defense when it updated its Free the Games fund policies.
