I like the fact that it's visual, it has most questions pre-defined and just waiting to be dragged in your survey. Most question options that one would need are also defined in the platform, you'd just have to check them (for example exclusives, other-specify, answer ranges for text or numeric questions, autosum and many other).
Confirmit learning curve is about 2 weeks, which is quite good considering the amount of features it is capable of providing. I found it faster to learn than Unicom Intelligence (former Dimensions). It does require some minimum programming knowledge (declare and work with variables, vectors, strings, use IF and FOR), it's not as fast as learning to work with other simpler solutions that only cover basic needs (Qualtrics, Survey Monkey etc.), but this is because it can do so much more than these tools.
As a business owner, it's just about choosing properly what suits your business needs, Confirmit is more complex but far more powerful. I see it better suited for corporations using it at a large scale than for a small company or single person. I also see it more suited for complex studies.
For people that want a Do-It-Yourself platform, Confirmit also offers an option that's better than most competitors out there. We tested it against Qualtrics and some other options and it scored highest on our side. It's simple and provides end-to-end solutions (survey creation, field management and deliveries / reporting).
It can do all 3 big data collection types: Online, CATI, CAPI - provides Android support for CAPI, too.
Fully online, access can happen from every computer connected to internet. Access to database is fast and simple (view or update included).
Reporting is pretty good, it has a dashboard with certain default reports that are nicer than in many other platforms. You can also configure your own reports in there.
Confirmit also allows more people to work simultaneously on the same project, speeding up the delivery of the survey link. It's easy and clear to do it.
Integrated debugging and testing options are pretty good. I used to often use the real-time question emulator, just to give my question a fast check and see how it displays. You also can create dummy data within the platform, which can be a life-saver when needing to check the survey logic for a complex study with multiple scenarios to be tested.
Templates and libraries can be created in Confirmit, to save up time when having to re-write modules or questions.
They offer hosting on both your servers and theirs, based on your needs. Hosting on their end is quite expensive though. Review collected by and hosted on G2.com.
