Question
Do I build a mockup page and advertise it on the right side of the Facebook page, along with other ads?
Do I make a survey of potential customers to see if they're willing to pay for the app (SurveyMonkey, or smtg else?)?
Should I build at least MVP to give potential customers a taste test?
Thanks.
Answer
Surveys are a great way to test the demand for your product or app. They provide a wide range of tools and features for measuring responses, so you can really do as much or as little as you want with the results.
One option that doesn't require any design skills and also creates beautiful surveys is Fieldboom (http://www.fieldboom.com/), which can create online forms and surveys in less than five minutes.
You can analyze responses one-by-one and also tag them with labels, star them and mark them as read or unread (just like Gmail). You can also use the simple but powerful reports to understand trends in the feedback you’re receiving.
No matter what survey option you go with, be sure to try it out before moving forward: You want to find the one that works best for you.
