Great for content creAters

This is great for content creators that are uploading big files and can’t wait because they have jobs to go to and they upload a video so as for me I have to wait until my video is completely uploaded for me to make my thumbnail because the app that I use is associated with the website that I’m uploading my video so until my videos completely uploaded I can’t make my thumbnails well with this I can make my son now and I already have it ready to go and attach it to the file so as soon as my videos done all I have to do is let it go public and this way I don’t have to wait or waste another day because I get home late night he could go out that same dayAnd at the fraction of the cost of other expensive cropping and editing some now creators this does a lot more and is way better

Very Good

I use this app all the time and it works very well. I love the option to save things with a transparent background or not. I also love how easy it is to take the background out of things! I would totally recommend this because it is free and simple to use. Some apps have way too much going on or the layout is confusing, but that’s definitely not the case with this one! I’ve been using it for 6 months now and I have absolutely no complaints!

Btw: when I open the app it says “konckout” instead of knockout. Just thought I should let you know.


Works great until the upgrade to 14 if your Apple product won’t upgrade to 14 don’t bother to buy

Purchased this product for work.I needed some light photo editing software for certain items that I do it works great the upgrade came and I have an older iPad I did not upgrade to 14 now every time I open it or try to use it is simply crashes. I am extremely disappointed especially the price that I paid and it works so well at the beginning obviously they either need to fix that since it says it still works on my iPad or say that it doesn’t work on this iPad anymore I know that I’m out the money. I’m extremely disappointed that this did not live up to the expectation and they don’t have a properly fixed to work with my iPad and the 14 patch again another disappointment from an Apple product
