We just tested their newly released EasyCanvas Pro for Android . I own a Samsung Note 8 with S Pen, which supports both pressure and tilt, so I used it in this test. Normally, you should use a tablet instead since a phone's screen is very small for painting.
We hope DEVGURU can support G-Sensor data and hover in the future. G-Sensor can be used for surface tilt to direct the paint flow, and hover is good for users to see the pen posture before hitting the paper. This is important for Eastern calligraphy, if not for painting in general.
