While their unlimited storage and swipe questions are nice (even though swiping between two choices has a limited use case), these are the only unique aspects of this tool, in my opinion. However, these features don't make up for the app's overall limitations, as most of the features it offers can be attained at a much lower cost using other tools on AppSumo that have even more advanced capabilities, like Formly, for example.

Other basic limitations of MetaSurvey include:
🚫 1) Custom HTML isn’t supported
🚫 2) Cannot modify font styles (only colors)
🚫 3) CSV import only supports swipe questions with Yes/No answers. Not possible to import multiple-choice questions.
🚫 4) Respondents cannot upload files (which is where unlimited storage would really be a benefit)
🚫 5) Cannot use a keyboard to navigate all question types (only a few)
🚫 6) Cannot use variables (like first name or their score in questions)
🚫 7) Cannot add an image to all question types (only swipe questions)
🚫 8) Cannot rank items as a question type
🚫 9) Cannot provide respondents the option to skip a question, as all questions must be answered (which is a turn-off for most people). The ability to make some questions optional is a basic survey feature that most people expect, so it is embarrassing as a survey developer to have to add "Do not wish to answer" as a choice. Even as a highly voted feature, there is no indication this will be possible soon.
🚫 10) It advertises that you can "easily" translate surveys into any language "manually", which is contradictory as this puts all the effort on you. There is no language menu option to accomplish any part of this automatically (even the interface text must be translated manually).
🚫 11) Only 1 user can access an account (extra charge for additional users)

Considering that MetaSurvey has been on AppSumo nearly non-stop since 2021 and has less than 50 reviews, this is very telling. It also raises concerns about their MRR and explains why the product has been lingering on the platform for so long.

*Note to seller: If any of the missing features listed above have already been released and I am mistaken, please specify which ones for the benefit of everyone. Also, can you please explain why none of these are listed under the "roadmap" category as you stated in your original response but instead are still listed as or have been downgraded to "gathering votes"? In fact, the only item currently listed under the "roadmap" section is the dynamic variables feature, which only has 11 votes (quite low compared to many other more basic feature requests with more than twice the number of votes). So what is the purpose of asking users to vote on a feature if more popular requests for essential features, like the ability to add images to all question types or the ability to make some questions optional, are not being prioritized year after year? 🤔
