Skitch is currently featured in the Android Market, which more than likely helped them pass the million mark so quickly. It’s still an impressive feat, though.
Taking screenshots isn’t an easy thing to do on the Android OS oddly, so Skitch is the perfect quick editor that compliments Evernote’s desktop and mobile suite of products. Evernote purchased Skitch in August, and made the full product free for all users.
The Android Market has gone through re-designs and is attracting more developers to its platform. Success stories like this will most certainly draw more iOS focused developers to port their apps over to Android. Evernote also demoed its Windows Phone version for the Mango OS at last nights HTC Radar release party, perhaps they’ll find similar success with it.
