I think I've tried every sketching app out there on the various platforms... Following is a list of my go to SKETCHING apps and is not an indication of all sketching apps available on each platform. These are apps I use regularly or have used regularly in the past with the primary goal of using it as my digital sketch tablet. Sketch = quick sketches, ideation, concept generation NOT full illustrations, paintings, and/or renderings.
I currently own an iPhone 6, Windows 8 computer with pen display tablet, iMac with bamboo graphite tablet, and an Android Galaxy Note 8.0 tablet. Of these, I do most of my regular sketching on my Window 8 computer, Galaxy Note 8.0 tablet, and with traditional pen and paper.
My criteria for a good sketching app:
1. Easy to understand UI
2. Quick jump in and out UX
3. Quick access to common drawing tools like: pen size, brush opacity, eraser
The app should not slow me down or get in the way of my sketching
4. Real or simulated pressure sensitivity
5. Some organization of completed sketches
