Procreate offers this kind of snapping when using the quickline/quickshape, using increments of 15 degrees when putting a finger on the canvas.
Clip Studio offers the ability to set the "step of angle" for the line tools, which can be set to any angle. If this option is checked it will only draw on these angles. Clip studio has the option for other shape tools as well, for instance it is possible to draw a rectangle with the rectangle tool, then specify the angle it is set at. This angle can be constrained to any angle you wish.
