Very cool, congrats!

just one minor suggestion: It seems that the responses are not saved anywhere? even after signup, opening a new tab or just navigating within the app makes the responses disappear - if they're really not being stored, might be worth considering storing them. if they are, maybe the ux could make that more obvious (I couldn't find it). in any case, very useful project!

You're absolutely right. Currently they are not stored. This is one of the things that are on my short list.
