Well, if you are talking about a software to collect data, I recommend the typeform. On the other hand, to analyze survey data, I usually use R or SPSS.
My preferred package is Stata. It has a core code, as SPSS, which means that the way to do most things is shared by most users, and it has add-ons, which work in a similar fashion to R's libraries and hence provide all the flexibility u need (but u only need to download them once in Stata). If u're good with maths, then u can use its mata environment. Its statistical procedures are excellent as well. If u do not have funding, then u may consider R, which is free.
