Tried to use it via freedomstore.io on a fresh iPhone.

Their freedomstore json file with all the app data was not working , was able to find an old version of it on GitHub and hosted it myself by pointing alt store to it.

Was not able to load non notarized ipa files. Unclear if it’s possible to notarize an app without Apple’s involvement.

Other apps listed there load well but choice is limited right now.

You will also need to have an apple account to use it.
