Good data collection tool. You can create all sorts of branchings required in the survey. It also stores the data well and the output that you get out of it is in a readable format. It helps in taking quick decisions.

Collects relevant data, super customizable. SurveyCTO does the job when offline, which is great.

I particularly like the variety of survey topics and issues it qualify a participant. It also has fewer to none technical problems encountered once used.
