An app that allows tourists/visitors/people new to an area to ask questions about the area and sends push notifications to a select number of users within a certain radius of where the question is asked.
Since online sources are always biased towards paid advertising or benefits businesses with a strong online presence, simply googling information about an area simply does not give you the same insights that speaking to a local would.
When a user posts a question, it is sent to a set amount of other users within the same area. They receive a push notification and will be incentivised to answer to the best of their abilities by a rating system/ badge system/ or perhaps even a tipping system.
Answers and questions will be rated, and a user's rating will determine how often they are allowed to post a question and how often they receive questions, and to whom their questions are sent and who's questions they receive. Ideally, this will result in users who give good advice having access to other users who give good advice when they need it.
Top rated answers can remain public, so that users don't get repeats of the same question every day. There would be no commenting on or discussing answers. Users would simply have a bar in which to type their question. Keywords would bring up previous, related answers. And only the set amount of people who receive the question will be able to answer (if a satisfying answer has not been received after a set amount of time, users would be allowed to post the question again to a different group of people)
There are a number of apps, platforms, articles and groups that attempt to offer this service already. Of these, I feel like only groups on different social media platforms are really able to provide up to date, relevant answers to some of the questions newcomers might have, but they are usually restricted to people who already live in the area, so they do not really serve visitors.
Most apps are simply advertising space for paying businesses, so they do not really provide users with unbiased, good advise. Of the existing platforms, I believe Quora resembles my idea most, but of course Quora doesn't limit who is allowed to answer, does not send push notifications and often requires you to read through long threads of debate and trolling before finding what you are looking for.
What sets this idea apart from all the other apps and articles available online is that questions are asked and answers are given in pretty much real time and it ensures that answers come from real people in the area.
The app would be most effective if there is an abundance of users who could potentially answer questions. So getting people to sign on at first will be most the most challenging part. This is why I believe it might be a good idea to monetize the rewards for giving good answers. This would come with its own set of challenges but should ultimately be doable.
How else would you get the platform to grow to a point where there are enough users for it to be able to sustain itself?
