I think you should not rely on the success of the project if they have an app on Apple Store and Playstore, some of them have just develop in order to showcase a product but to be honest lots of project have it but no use at all. Its not hard to put an app on these places. Hire a good developer and one week you can have an initial app already. What is important in a project is a working product and tested, that's why they settle first for beta then users can experience it and give feedback.
