I've used a LOT of really good mobile iOS editors out there (and some ridiculously bad ones) and this surprised me. Initially I just wanted an app that featured masking for subtle adjustments to focus. But, once I started using this and seeing how incredibly easy it was to create decent masks, (seriously, it's almost better than doing with PS on my desktop!) I explored the countless other options this app offers. Now, after buying the full app, it's become my go to editor! There is one annoyance, however. (Thus the 4 out of 5 stars).When I access my Photos library and select 'All Photos' only a very small selection of seemingly random images appears. I've come to conclude this is because they have been adjusted or were captured with my phone. The majority of images in my library that if want to edit are RAW files (cr2 and Panasonic). To get them to appear in Tadaa I have to first apply an edit in Photos (a small crop adjustment, etc.). Knowing this I can at least work around the problem, but since I don't experience the issue in other apps, I can only guess it's a bug or compatibility issue.In any case, this app is well worth downloading, and I'd say pick up the full app. The $10 or whatever is a drop in the bucket for all you get here.
