Launched over Christmas the Appvent Calendar, which offered a different free iPhone game every day, was a huge success.

At least, it was a huge success in terms of generating tens of thousands of free downloads of those free games. (We've yet to hear whether it led to an increase of paid sales in the following days.)

But with the discovery of games via the App Store an increasingly difficult task, a plan is underway to make Appvent Calendar a daily occurrence.

Set up by Joe Bayen of ICS Mobile (of Navy Patrol: Coastal Defense fame), as well as Blacksmith Games (Plushed), which also set up Appvent Calendar, mobile advertiser tech provider TapJoy, and OpenFeint, the social gaming network, FreeAppaDay.com will go live on 18th January.

It will feature one free app daily, as well as providing visibility for previously free apps. Consumers will also be able to set up email notifications for free applications available in their category of interest, such as arcade, sports, utility etc.

"Our experience with Appvent Calendar was tremendous" said Joe Bayen, CEO at ICS Mobile. "We recorded over 100,000 downloads over the Christmas week for Navy Patrol, peaking at the 53rd spot of the total game category within hours. Adding the OpenFeint social gaming network and TapJoy's pay-per-install solution were additional great tools to help increase the visibility of our application."

"OpenFeint is happy to participate with ICS in launching FreeAppaDay," said Eros Resmini, veep marketing & developer relations at Aurora Feint, the company behind OpenFeint.

"Additionally, we'll be adding OpenFeint-enabled games to our new standalone app's 'free game of the day' promotion, giving developers strong download lift across two new touchpoints."
