Freeform - The Vector Drawing App full review
Freeform is a vector tool, meaning you can modify and resize all your objects without running into pixelation problems.
The tools offered with this program are vast. You have full creative control over some basic shapes: circle, square, triangle, star, line or freeform. Colours are a breeze, even adding radial or linear gradients using multiple colours. Everything feels intuitive and is a joy to use.
