Marketing is an often overlooked and underestimated topic for apps. Just because you made a great app does not mean that people will find it.
You should at least create an landing page for your app, and ideally before you build your app.
Your app’s page needs the following components:
1. A clear headline at the top of the page
2. A brief introductory paragraph or explainer video
3. An app screenshot or iPhone mockup
4. A call to action, i.e. to sign up or install the app
5. A breakdown of app features and benefits
6. A story about the app’s creators, or an “About Us” section
