If you want evidence-driven service, then CaseWorthy is the best. I’ve designed and used primary data collection systems for 26 years and helped many non-profits “work-around” the limitations in their off-the shelf software products. My main objective was to find a product that could be customized without going back to the vendor to pay and pay. You will not need to create “work-arounds” with CaseWorthy.
CaseWorthy is a different level of architecture, with a uniquely flexible and expandable design. You can add almost anything you can imagine, most likely without having to go back to the vendor or pay anything additional.
