I recently released an Ionic Starter App to help jumpstart Camera app development using cordova on iOS and Android.
A simple barebone ionic camera application for iOS and Android that takes photos or loads them from the library and displays them on a canvas. You can then rotate the images and share them via the share sheet or upload them to your server. On iOS save image is supported from the share sheet. For android you will have to add separate button to save images. The Image is drawn onto a canvas for easy image manipulation.
Check it out on the ionic marketplace.
