There is nothing more rewarding than watching people use your app and seeing how they interact with it. User testing is a lot like making dinner for someone; you choose a recipe, ingredients, and invest time making a meal you hope your guests will like. Then you sit down with them and talk about what is good about the meal, what could be improved, and if you’d make it again. At Bitovi, we put a lot of value on testing our designs (and our assumptions!) to be sure we’re building the right thing for our clients and our clients' customers.
