There are plenty of sites which offer online survey functionality, but not all of them produce particularly attractive-looking results. Australian-developed Floq doesn't fall into that trap, produced attractive surveys that are easy to share and collate.
Floq, which has just exited private beta, includes some good-looking templates for automatically creating common team surveys, such as performance reviews or feedback after an event. You can also design your own surveys from scratch in a drag-and-drop environment.
The basic Floq account is free, and allows two active surveys with 20 questions each. Paid accounts start from $49 a month and include additional features such as benchmarking your results against others.
