5 stars: Woah. This... is... what I've always hoped digital sketching could be. Intuitive, uncluttered, fast, dependable -- and yet, very accommodating to real, sketchy drawing styles. Especially the styles where as much of the character is in the random imperfections of the rendering as the draftsmanship of the structure revealed. Thank you, thank you... thank you!
4 stars: I am using concepts on my Samsung Tab S7+ and I absolutely love it! The app takes a bit of getting used to but I love all of the different styles of drawing utensils there are. I deducted a star, however, because there is a delay in the reverse option which leaves you waiting to find out if it worked or if you need to hit it again before you can move on. Otherwise, fantastic app.
2 stars: I would give this two and a half, but I can't. The reason why I didn't rate it 5 is because most of the advertized features (including editing,) are paid subscription features. It would be nice if you could at least make the editing unpaid, and something else would be if you could make certain other items, or all items, a one time pay type of thing.
