Basically the editors uses these 3 editors mainly- Picsart- Photostudio (Android), Photoshop (Pc), Photoscape (Pc) but I recommended you to use picsart if you are a android user to enjoy the more effects and features for editing in android phone you never seen before in any android photo editor app.
I Hope many you familier about Photoshop software which is for pc which is really pretty advanced and working on many platforms and developed by Abobe It is used as a commercial as well personal private use also many banners, images, wallpapers design with it because it is really advanced but also hard for first time user.
But on other side for pc Photoscape is really really also awesome editor for new editors and it can also do that work which photoshop do but the condition is that. It contain some less features as compare to photoshop software by adobe.
Picsart is one of the best editor in the world for android phone and according to me it is not lesser then photoshop it contains all best features in it. This editor is for android phone and really it is easy to use for everyone and it also have huge features also so it is the combination of photoshop+photoscape which is for newbie as well as expert also.
