Adding custom repo might not be as secure as the official one so I'm not responsable if you encounter any problems with them ! I encourage you to do your own research about it !
Also while open source is great for privacy and security it is not perfect. So keep that in mind before downloading any apps. Most apps that I've listed are privacy friendly but some might be not be perfectly private and secure. I again encourage you to do your own research about them.
I am not a privacy and security expert. I'm also don't consider myself as a developper so I do not have any technical knowledge and so I didn't look into any source code of any apps in this list !

Amazing. Can't believe I didn't find this list sooner. My F-Droid client of choice is Droid-ify.
F-Droid is operated by a censorship-prone megalomaniac. Freedom only for special people.
Might be worth adding this: raw.githubusercontent.com/efreak/auto-daily-fdroid/main/fdroid/repo Unofficial repo of Tachiyomi and known forks (SY, AZ, J2K, Neko; also Takoyomi, Sorayami, Aniyomi, Animiru), FastHub Revived, and Hacki (flutter HN client).
Hi, I love the concept of Echo, but it is not maintained, it's buggy and missing many features. Do you know about any alternative? Thanks
No I'm sorry, can't help you on that
Hey it's been a long time but maybe if you still are looking for such an app you could try
Alibi
I have a recommendation for the "Screen addiction" part.
TimeLimit.io can be set up to automatically block certain apps after you use them for a configured amount of time. It is highly customisable. If you don't trust yourself, you can autogenerate a password and give it to a friend or family member so you need to ask for it every time you want to change something.
You should add this app in "Social & communication PART VII - Twitter" section The app Is called harpy https://github.com/robertodoering/harpy
I know Harpy, but do you know if it's on a f-droid repository ? It's not on the official one or the IzzyOnDroid and I couldn't find any repo on their GitHub
You can find this app in one of my other list :
Unfortunately it is not on f-droid or izzyondroid . its only available through play store beta testing and you can download it from github also
I will make a request in their github page to add it to izzy's repo
The dev of harpy quoted this
"There are no plans to bring harpy to f-droid at the moment but if you want to avoid the play store you can download the latest apk here: https://github.com/robertodoering/harpy/releases"
A few more recommendations:
QuickTiles: Add a lot of useful Quick Settings tiles https://f-droid.org/en/packages/com.asdoi.quicktiles/
Forkyz: Crossword puzzles - Guardian cryptic, WSJ, and more, plus support for local puzzle files in a variety of formats https://f-droid.org/en/packages/app.crossword.yourealwaysbe.forkyz/
SimpleReminder: Quickly create reminders and get notified later https://f-droid.org/packages/felixwiemuth.simplereminder/
Easy Noise: Simple white noise app (full disclosure: I made this one) https://f-droid.org/en/packages/com.cliambrown.easynoise/
I'll take thoses in consideration, wanna add many many many more apps but since I have to add them to AlternativeTo it takes some times wich I don't have at the moment ^^'
