 #### Which client do you recommend?
 
-Honestly the only one that I can recommend is [Nheko nightly flatpak](https://flatpak.neko.dev/repo/nightly/appstream/io.github.NhekoReborn.Nheko.flatpakref), even if it's also missing features I care about such as [Stories (#1038)](https://github.com/Nheko-Reborn/nheko/issues/1038).
+Honestly the only one that I can recommend is [Nheko nightly flatpak](#how-can-i-install-nheko-nightly).
 
 I have also said it before, but for any serious use of Matrix, you will need [Element Web](https://github.com/vector-im/element-web) and especially the `/devtools` command it has.
 
 If you absolutely need Matrix somewhere neither fits you, ~~maybe [Hydrogen](https://github.com/vector-im/hydrogen-web) is your _PWA_ hoping your needs don't include too many Matrix accounts ([#783](https://github.com/vector-im/hydrogen-web/issues/783), [#817](https://github.com/vector-im/hydrogen-web/pull/817)) and hoping you [don't use SailfishOS](https://forum.sailfishos.org/t/progressive-web-app-pwa-in-native-browser/3867?u=mikaela) ([#1000](https://github.com/sailfishos/sailfish-browser/issues/1000)) or [Ubuntu Touch (#1144)](https://github.com/ubports/ubuntu-touch/issues/1144).~~ Good luck!
 
+On Android I often find myself using [SchildiChat](https://s2.spiritcroc.de/fdroid/repo) ([Beta](https://s2.spiritcroc.de/testing/fdroid/repo)), which suffers many Element shortcomings being a fork and Matrix isn't too mobile friendly protocol in my opinion. (For my view of the repo fingerprints, refer to [n/f-droid](n/f-droid.html), but note the pages intend of _my personal use._)
