How can I promote an app that I have built? it currently has 0 users and I have no friends or family to show it to
There are a few things you could do to help promote your app:
* Build social media accounts for your app.
    - Use platforms such as Twitter, Instagram, Facebook etc.
    - Promote your app through posts, mentions, comments on relevant posts by others.
* Attend events related to technology.
    - This will give you the opportunity to meet people from different walks of life who might be interested in using your app.
    - You can also learn more about how other apps are promoted in this context.
* Partner with businesses/organizations that cater to your target audience (for example, if your app is targeted towards students, partner with universities).
    - They can use your app as part of their marketing strategies and offer discounts or other incentives to users who sign up for your app via them.

Remember, promoting your app takes time and effort, so don't get discouraged if there isn't immediate success. Keep plugging away and building relationships with both users and businesses in the tech ecosystem. Good luck!
