Combining a really simple interface with a very powerful set of options for a free tool, GridPapr is a new alternative for the creation and prototyping of grid-based designs.
Using GridPapr, just anybody can set down the different parts of any such design, and pinpoint their exact location in just a matter of clicks. Categories, sections and even photographs can be placed where they should be. There is actually no limit to the number of building blocks to be employed by the user.
And any design that is created through the site can be kept public or private. That is up to the user, and a private account cost only $ 5 per month. Note that only those who go for a paid account are enabled to share what they have designed directly with their peers and colleagues. And free accounts are limited in the sense that you will only be able to create 5 papers. If you need to create more than that, then you will have to upgrade your account.
