The basic idea is a review app for landlords and tenants.
The landlord or letting agency would have an account with all of there properties on and tenants would have personal accounts.
Both landlords and tenants would review each other and you could view peoples reviews on their profile. A new tenant could then see what experiences other tenants have had with their landlord and vice versa.
I'm also thinking of having a communication part of the app for a quick and easy way to communicate with your landlord and report any issues to them.
Did either landlords or tenants ask you for it?
Did they say they had a problem this solution can fix?
Are they willing to pay for it--or is someone willing to pay for it? Possibly a third party advertiser?
Have you figured out your business model?
How do you protect the app from being "gamed" with fake reviews, positive and negative?
Run it by an expert. And together you can go through the business planning of this idea. An expert should be able to spot flaws in your strategy and suggest workarounds. Together, you will work to refine the original plan so it can be successful.
Another key component to this is defining what success means for you and your app. Think both in terms of the broader objectives (generate revenue, be acquired, be a side hustle business etc) and app-specific (acquire new users, retain users, have high MAU or DAU numbers etc.) I've helped entrepreneurs launch dozens and dozens of applications and a lot of them had seperate goals in mind. some wanted to go viral and got hundreds of thousands of downloads in a few months (rare but it can happen); some wanted to create a companion application for their existing retail business; others wanted to just experience building and marketing an application for a few enterprise-level B2B clients. in order to evaluate whether or not your application would be (or how it can be) validated it's important to first start with what you define the finish line as. I'd be happy to connect and discuss more about goal setting and some validation models/steps you can take to test market readiness with your app idea (both before and including actual development.)
There's no guarantees that any new app will be successful, but one way is to test the app with a closed customer group and get feedback. You also have to look at how your app is going to make you money.
