New app was approved a week ago but no one can find it in the App Store

Your app is indexed and searchable — but only in the US store. I checked with the public iTunes API just now: Searching "YouWorth" in the US store returns your app in position 1. A lookup by ID succeeds for country=us, but returns nothing for country=es or country=gb. So the app is only available in the United States. Anyone searching from another storefront will never see it, no matter what they type. If the people who "cannot find it" are outside the US, that is your answer — check Pricing and Availability in App Store Connect and confirm which countries are selected. Two other things worth knowing: Your original release date is 22 August, but version 1.1 went live on 29 August. Search indexing is not instant — it can take 24-48h after a new version — so if you tested right after that update, you may simply have looked too early. Your listing is English-only. That does not block search, but it limits how you rank on non-English terms in other storefronts if you expand later. You can verify any of this yourself without waiting: https://itunes.apple.com/lookup?id=6762416926&country=us versus the same URL with country=gb. If one returns a result and the other returns zero, it is availability, not indexing.

That's common. Many people complain about that. But with over two million apps, searching is going to be a challenge.

Being available only in the US may also negatively impact your search results.

To be honest, search was never one of Apple's strengths. I don't think it's a good idea to rely solely on the App Store for discovery.
