Ever been bored waiting and waiting -on public transportation till you get to your destination, on dates for your mate's arrival, on classes for the sessions to start, and...- wondering if there's an android app you can make some quick sketch or even decent designs on?
"Sketch" might just be the right app for you!

I've made this piece on Sketch, using fingers only.
I like the app's user interface. it offers the capability of making multiple layers, editing them, and... in addition to not very diverse, but quite handy brushes.
However, I wouldn't recommend it for extra detailed works and any designs that require +2340px. [Which, in my opinion, is not a problem as PCs are supposed to be used for running thorough projects.]

👇 Here's the app logo!

Sketch tips:

• if you want to go crazy with some extra details, you can always work on detailed objects on a bigger scale (as you can see on the following pictures) then, import them into the background.

• To simulate the texture of dark surfaces, draw a silhouette of the darkest tone in the surface first, and then start shading it, using a low opacity of the lightest tone.
