Photoshop-style bitmap image editors work with pixels, and therefore require large file sizes in order to preserve resolution. By comparison, vector-based illustrations are lightweight and able to scale up or down without a loss in quality, but finding quality App Store solutions for creating and editing such files can be a challenge. One such option is Inkpad, which has now gone from paid to free with the most recent release – and not the kind of free that involves in-app purchases to be useful. Instead, developer Taptrix made the app open source, allowing others to build upon its work and contribute to future versions.
There's a great idea behind Adobe Ideas--simply whip out your iPhone or iPad, and you can draw vector illustrations of your own at will, all without the cost of spending a small fortune on Adobe Illustrator. Until now, it's largely been limited by its reliance on touch-based input, but creatives can now use a stylus with the freeform app as of the newest patch and take advantage of options for stroke smoothing, exponentially increasing its usefulness.
Before you write the new iOS 6-based Maps app off as a total loser, consider this: Its vector-based maps are actually capable of taking you further without an internet connection, thanks to automatic caching.
Enterprising indie software developers trying to gain ground on the industry’s major players can take a couple of approaches. One is to ape what’s come before, but with a fraction of the resources. Another is to try to do something entirely new. Sketch 2 goes with the ballsier tactic, and largely succeeds in creating a sleek and modern app for crafting vector graphics.
