What’s Coming Up Next? – MacHouse Introducing JustTomato for Mac OS X

Mac software JustTomato

TOKYO (MacHouse) – Last year, we exclusively developed Windows application. For now, we are done with Windows because Microsoft appears to destroy the desktop application community. So we started developing iOS applications last November. We did so just till the very end of the last month. Then we’ve suddenly switched back to Mac OS X. So far, we’ve released two Mac applications. Before this month ends, we happen to have one more Mac application to introduce. This new Mac software title is called JustTomato. JustTomato? You mean, grow virtual tomatoes on your Mac? Nope.
