co.he.valuate is a collaborative heuristic evaluation tool that allows experts to evaluate applications remotely and generate professional reports. It enables experts to collaborate with others anywhere and anytime, and developers and designers to upload apps for evaluation and view expert credentials. Experts can use the single page workspace to mark issues on application slides, view other experts' comments, and access a database of common issues. Reports generated by the tool prioritize issues by severity and include an introduction and overall insights.
