What modern filtered user-centric iOS app search engines do you know of?

Since it's a universal need of intelligent people to be able to search for
apps using a variety of modern filters, I looked for iOS app store engines.
<https://www.macworld.com/article/671296/best-way-to-find-apps-on-the-apple-app-store.html>
a. Use Google (which is how I found the helpful links you see below)
b. Ask in discussions (which is what I'm doing now)
c. Use Vionza (the link provided seems to only be for the Mac)
d. Use Fnd <https://fnd.io/>

I'm doing (in steps a & b) exactly what they recommended to find iOS apps
that have features I care about (e.g., free and ad free and with a certain
rating and certain number of downloads and targeted to a certain API or
phone make & model and (of course) the ability to save the installer
APK/IPA onto the phones's storage for automatic backup, etc.)
all of which the Aurora Store skin to the Google Play Store repo does.
Even better, the aforementioned App Finder skin for the Google Play Store
repo can search by category by country, by rating, by number of ratings, by
release date, by being free and ad free or whether it accepts Play Pass,
and whether or not it has in-app purchases, by the number of downloads, by
a price range, by the in-app price range, by the last date updated, by the
content rating, by the required Android API level, by the target API, etc.

There must be similar apps for iOS since the mothership will never provide
them so I searched Google and I'm asking here if you know of good engines.

My search did find SerpApi's Apple App Store Scraper API which uses JSON.

And, of course, the question I ask was asked on StackExchange 6 years ago.
<https://apple.stackexchange.com/questions/301584/how-can-i-browse-or-search-the-ios-app-store-from-my-desktop>

Which, helpfully, suggested this browser-based search URI to find iOS apps.
<https://www.apple.com/us/search?src=serp>

In summary, following the suggested steps to find a non-primitive modern
search engine for iOS apps, I googled (see results above) and now I'm
asking the user community to add value to this important-to-answer query.

What's a modern filtered user-centric (hopefully PC-based) search engine
for finding iOS apps that you know of (which isn't yet listed above)?

I use iOS & Android every day where I strive to learn as much as I can
about each system, and to be able to do the same things on both devices.

Similar to the google play scraper
https://github.com/facundoolano/google-play-scraper

The iOS/Mac scraper facundoolano might be of use to you
https://github.com/facundoolano/app-store-scraper

Node.js module to scrape application data from the iTunes/Mac App Store.
The goal is to provide an interface as close as possible to the
google-play-scraper module.

The Google Play Store app search engine is just as atrociously primitive as
is the Apple App Store app search engine - but at least alternatives exist.

App Finder by Skyica LLC (free, adfree, gsfree)
<https://play.google.com/store/apps/details?id=scadica.aq>

Aurora OSS based on Sergei Yeriomin's Yalp (free, adfree, gsfree)
<https://www.auroraoss.com/>

Both those *modern app search engines* accurately search the official
Google Play Store repository using a huge variety of rather modern
extremely useful customer-centric functional filters (which the greedy
money-making Apple/Google motherships will _never_ provide to users!).
<https://developer.apple.com/app-store/search/>

True to form for motherships, the search engine provided by Google sucks.
Google Play Store atrociously primitive search engine
<https://play.google.com/store/search?q=&c=apps>

As does the primitive browser-based search engine provided by Apple.
<https://www.apple.com/ios/app-store/>
(Use the magnifying glass in the top right to search the apps.)
