Amazing!
I can only recommend this app. If you want to give your images an artistic touch - with Aquarella you can. Whether you want to use random changes or presets or want to have the full control about the changes - you can. Saving time is - well not slow, that would not be fair to say - but a little bit slower than with other apps. That's why I give four stars. But hey ... the results are worth waiting for! Really!
