While AppoinTile uses two Live Tiles next to each other on Windows Phone 7.x, the double width tile in Windows Phone 8 (and also in Windows Phone 7.8 when it arrives) presents all the information the app used to, but in a much more practical layout.
AppoinTile costs £1.99 / $2.490 from the Windows Store, and comes with a fully function ten day free trial to see how well it fits in with the rest of your Live Tiles.
