I use this all the time because its quick to load and has practically any photoshop-esque filter and tool I'd ever need to use on a daily basis. It also has many unique features that are possible in other programs but are "one-click" solutions: creating zoom blur effects, altering, a unique symmetrical kaleidoscopic brush tool that can have a gravity effect applied, many easy to find color editing tools. You can send your images from the program straight to your email if you want in-program. It is much easier to use than GIMP. The interface is extremely clean and professional and best of all it can be used wherever one has internet.
Because it is a online program (unless you buy the pro version) it tends to lag and often slow to a halt when editing large image files (1080x1920 and above), this is understandable but occasionally when the program runs out of memory it will cause the program to either crash or freeze. This is a problem which is relatively minor provided you are only working on a small resolution image. Finally, because the program operates online, when using a tablet it tends to lag behind the brush somewhat which can be irritating. (However this issue is almost definitely eliminated if you buy the pro-downloadable version. (By the way that's really the only difference between the two, I have the pro version and it doesn't have anything added, the program is complete from the start).
Overall a free handy "pretty" image editing/ paint program that is well worth a try because it is entirely online. No signup is required in order to access it but if you do you can save files to a cloud server. I recommend it entirely.
I did buy SumoPro.I got no conformation or download url.I did send them a mail the same day,no answer,after a week a more urgent mail, I have had still no answer. The best is to stick to the free version and that is it. There is no service at all.
