Great - wish for high resolution


[updated review] FAQ updated. Increased 1 star. Effects look great. App works well. Developers have great responses. I eagerly hope for a full resolution option in future updates, even if it takes time for processing. Thank you for a good app.

[updated review] Website updated to remove resolution comment (increased 1 star) however FAQ still wrong.
Picture effects look nice. However, 1 star for lying: output resolution is not the same, it is significantly smaller. ( From the developer website FAQ: The resolution of the image will be the same size of your original. ) ( From developer website: Save photo in full resolution. )

Developer Response


Thank you for your review. Our output resolution is at optimum size to maintain a good app speed as our app require heavy processing algorithm. Thank you for pointing out our mistake. We missed out updating our website even though we have updated the app. We have updated the FAQ as well. Thank you!

Don’t be fooled you have to pay for every image!


This “freeL app for a day is not so free. You can make an picture into a “not so great” painting or sketch (Sketch Me is a better app for this) but to save it you are required to pay $2.99 per image. Not so friendly and not so free. Additionally, the app knocked me out four times, while trying to make the ONE sketch, just to advise that I had no Facebook friends with this app. Who cares?! Then you have to start over again from the beginning, finding a picture, selecting a types of setting (pencil, painting, etc.). I am thinking it’s really a scam to hunt for other people to pester! I deleted the app and recommend you avoid the app altogether and try “Sketch Me” instead.

Awesome effects, but. . .


Love the filters in this app—very different from the other art apps that I have used, especially the abstract filters!

After purchasing the abstract effects pack though, I am now unable to load any photo from my photo library into the app. Nothing happens, no matter how long I wait for the selected photo to download.

This app has great promise, if it would only work correctly. [Yes, my OS and my apps are all up to date, and I’m using the an on an iPad Pro.]
