Getting there...but not quite there yet!
We chose FastFieldForms as our platform for site assessments as it is significantly more affordable than other similar services on the market. It's relatively intuitive and the form builder is solid (7/10, can be clumsy when you want to copy and repeat sections).
The issue we have is the reporting side of things still isnt quite there yet. The ability to upload a custom report is excellent, however once you have done that there is very little flexibility in terms of changing report formats after site visits have been undertaken. Similarly, the report does not remove blank lines when you upload a custom template which means we have long reports that need to be manually updated by deleting all of the blank lines (takes hours!!).
For the price its pretty good, but we look forward to further update and more flexibility in reporting outputs (for example, being able to generate multiple types of reports from the one set of data rather than each assessment form being linked to a single report format).
