I was tasked with creating the phone app for the company I work for. Here are the key points: - The project took 2 months for me to learn the sencha framework AND to build the app from scratch (it's live in the app store). - The app performs well on the iphone 4, but the best performance is on the iphone 4S and later. - The Android version is not as smooth. It's significantly slower. This means it's not truly cross-platform. - People with the iphone 4S / 5 don't know it's not a native app until I tell them.
