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
Talk to people.
Talk about your idea, genuinely listen to their comments and feedback.
Once you've done that, build your MVP and always be testing. Always be gathering feedback.
I don't think the FB ads will work because there is nothing of value to the end user.
Happy to help more, book a call and we can discuss a strategy to get your app to market.
