MyPad, one of the more popular unofficial Facebook iPad apps, will push the first phase of a Twitter integration this week. MyPad developer Loytr’s co-founder Cole Ratias also tells us the integration of a games section into the app has been a success, with roughly 30 percent of the app’s nearly 550,000 daily active users entering the gaming area. He says that total ad impressions in the app have doubled.

When the Twitter integration deepens, it will give MyPad and Loytr’s games partners more viral reach. This is because users are prompted to share when they open games via MyPad. Both the Twitter integration and the games portal could help MyPad differentiate itself in preparation of the launch of Facebook’s official iPad app.

Since Facebook chose not to release an official iPad app, several tablet-optimized native app Facebook clients popped up. These include Oecoway’s Friendly, currently the largest with 600,000 DAU but losing users, and MyPad2, currently second with 548,000 DAU but growing such that it should overtake Friendly by the end of the month. Platform changes, which temporarily made Oecoway’s Friendly app not work properly, also helped with MyPad’s rise.

However, Loytr also has roughly 150,000 to 200,000 more users for MyPad1, which was built on touch.facebook.com opposed to the modern version that is built on the Graph API, meaning its total user count already surpasses Friendly.

These developers were able to make a comfortable living offering core Facebook functionality and some minor additional features such as color customization in ad-supported and premium versions of their apps.
