📝 About this app
Using map notes, you can spread your ideas anywhere on an infinitely spread canvas.
I think the brain's work when considering ideas is a random and radial working image rather than linear. Traditional notes that need to be written sequentially from left to right are not very suitable for this process. If you use this infinite size notebook application, you can freely expand ideas from the center of the page, so you can make ideas more natural. Ideal for creating rough mind maps, brainstorming and idea sketches.… View full description on the official store →
