In the running battle for iOS scanning supremacy, today Readdle released Scanner Pro 4.1. The interface overhaul is now complete and I like it. The grid lines in camera mode help me square the document and it runs its very own stability check when you snap the picture. Moreover, it now syncs everything between your devices with iCloud. With this update (along with the recent iPad optimized version), Scanner Pro has officially replaced JotNot in my life.
