Ignoring the design aspect. As a user, the first thing that stops me from trying it out is the "Try it for FREE" button. Especially for something so cutting-edge as an AI podcast generator, I think a simplified and limited demo on the landing page would work very well.

The way I would build it is by making a sleek prompt page (take inspiration from Claude/OpenAI, or others). Give some examples of prompts you can use and let people generate a new podcast.

Most of the suggested prompts can be pre-generated to reduce cost, but let the user play around and generate a new short podcast. If they want to save/download it then make them "Sign-up Here".

My 2 cents. I haven't built a mobile app but this is how I would do it:

Principles:

• Mobile users spend little time on the AppStore.

• They search directly for what they need to download.

• Like Amazon, search terms are very specific.

• The AppStore featured page is where you can capture the most traffic.

Steps:

1. Gather new app ideas from closely watching trends on explodingtopics.com/ or meetglimpse.com/

2. Check popular keywords on Google/AppStore autocomplete and discover sections. Verify these keywords via Google Trends to gauge interest. Then gauge traffic and competition in SEMrush or similar tool.

3. Competitor keyword research in SEMrush to see which keywords they are using.

4. Study what type of apps get featured and why. Then adapt your app to qualify to get featured on the main page:
   developer.apple.com/app-store…
   appfollow.io/blog/how-to-get-…

5. Once you get enough sales you will rank higher in your category so you will depend less on being featured and more on brand awareness and SEO.
