I wonder if you all know what it means? It's japanese.

If you say to a japanese "there's no Whatsapp for N900" (in japanese of course) he'd say "yappari" as "I knew it" or "I figure" or "no wonder".

But funny thing is that since Yappari exists and it is a Whatsapp for the N900, it is also the answer to the question. So it's a funny pun.

And it has "app" in between.
