Union despite only being two months old has already proved itself as a firm favourite with many mobile photographers. It has just had a new update with new brush settings to change size and opacity. There’s also the addition of a brush zoom window for details, two new blend modes – overlay and screen, bug fixes and performance improvements.
This is a free update, if you have previously downloaded this app. If not, you can download it here. It retails for $1.99/£1.49.
