Awsome software! All the reviews telling RelyThat saves you tons of time are true. You click a few times and you have a set of consistent artworks for your campaign. It can even help you to create a visual identity for a brand in really simple way.
RT has some limitations too. There is no CTRL+Z option ;) I haven't found cropping options for pictures too. Generally it's not very convinient to adjust projects. But it's said the templates are optimized for social media, so i believe this is the reason. These limitations aren't very annoying, becouse the templates you get are really beautiful and honestly there is no need to change them.
So, yes... I can recommend this software.
