Guidebook is revolutionizing a mobile app development market largely served by consultancies which offer custom apps for high upfront fees and unpredictable maintenance costs. Guidebook is the only fully functional app builder to offer a free version of its software. The company has lowered the traditionally high barrier to entry in the mobile app space by reducing the time it takes to launch a mobile guide to as little as an hour, and by offering a subscription model which eliminates startup fees and allows customers to predict ongoing costs.
