I wasn't aware of that app. I will check that one out too.
FYI the obtainx sources current list is: Fdroid, Fdroid 3rd party, Forgejo(Codeberg), GitHub, GitLab, IzzyOnDroid, CoolApk, Tencent App Store, vivo App Store (CN).
So "Fdroid, Fdroid 3rd party, Forgejo(Codeberg), GitHub, GitLab, IzzyOnDroid, CoolApk, Tencent App Store, vivo App Store (CN)"
VS
"APKMirror, Aptoide, F-Droid, IzzyOnDroid, APKPure, GitLab and GitHub"
so 3 chinese app stores vs APKMirror, APKPure and Aptoide, I think I'd trust more APKM over the rest, personally I update only from Github/Fdroid and APKPure/Aptoide I have disabled

I only ever used Github so far.
