Adobe IdeasiTunes link: Adobe Ideas - Â£Free
Adobe Ideas is sort of like a digital sketch pad for your iPhone or iPad that lets you map out ideas for your projects using a number of features including pictures, text and drawing tools. Itâ€™s really targeted at designers and is compatible with a range of Adobeâ€™s professional software packages.
You can either start with a blank canvas or load in existing photos stored on your phone and then work from there. It lets you draw using the vector tools or grab colours directly from a photo youâ€™ve taken and itâ€™s easy to export your sketches as PDF files. Although the main app is free, if you want to add the capability to use different layers in your sketch books then you have to shell out for it via an in-app purchase, which costs $4.99.
Adobe Ideas is a great tool for designers who want to quickly gather together concepts for ideas theyâ€™ll work on later.
