At the moment this is what I can recommend that I haven’t seen already here.

pc/server:

• Geany as my graphical IDE (Mainly for the debugger interface. I’, still learning to use plugins with vim and gdb from cli is a bit overwelming, to say the least)
• hledger or ledger as a cli personal finance manager. It features double-bookkeeping and rocks a very well documented text format. The data is directly accessible with any editor you want. If the cli is not for you, you can use the tui mode thanks to ncurses or a simple webpage opened locally on your computer, thanks to hledger-web. I discovered it after I started to care more about accessibility of data. The migration from my previous manager (silverstrike) was smooth thanks to awk.
• Nextcloud as a personal web storage. It allows federation with other nextcloud instances if needed and it can also be expanded with a lot of plugins for other necessities, making it a groupware platform.
  Altough I only need to sync data, I can’t move to syncthing because I haven’t found a way to sync only on demand, while still viewing that something has changed on the remote counterpart.
• FunkWhale is a music listening platform that is just starting to come out of it’s nest. I started using it a week ago to discover non-mainstream music. At the moment there are only a handful of pods, but sometimes I come across something I like. I really suggest to give it a shot.
• Gitea for hosting git repos at home. Great open source project which powers its own hosting site and another one with a custom blue/white theme (although I can’t remember the name, my bad).
• Hugo is a powerful static site generator. I use it to process my plaintext markdown files to add an aestetic touch to my personal wiki.
  Before adopting it, I used dokuwiki. They are both great tools, although they serve different purposes and hugo does just fine for me. I did not need the embedded editor, or the upload button, nor the multi-person login. And on top of that, I just use a static webserver, no more php. Less is more, right?
• Miniflux as an hosted feed aggregator. I tried to go host-less but syncronisation was a bit of a pain for me. When I returned on the hosted path, I switched to this program. It’s fast, minimal and has a low footprint. It could run on a pi1 probably without complaining a bit. Maybe the only downside is that it forces users to adopt postgres.
• Finally, I shut down my shaarli instance in favour of a simple script I wrote to manage my bookmarks. The rationale is still the “go human readable files, go host-less” approach I am preferring lately, but I still recommend that software.

phone (android specifically). These recommendations should be google-less, as I have a google-free rom and no app complains:

• orgzly is an org-mode notes and todo writer. Notes can be synced in another local folder or with a webdav server. On pc you can open them with emacs (natively), with vim using a plugin for syntax highlighting or with another editor. Well, you could even use sed. Anyone has its favorite tools.
• davx does a great job at syncing calendars, tasks and contacts with a caldav server like Radicale.
• decsync cc is an alternative to davx that works by leveraging a local directory and by saving everything in ics files. It handles concurreny by using different folders as sync points and by using a different id for each device in that folder. The folder can then be synced with syncthing, nextcloud etcetera.
• etesync is another contact and calendar sync solution that works with its server counterpart and promotes e2ee. It also provides a cheap (2 dollars/month) hosted account if someone can’t host at home.
• untrack me is a small app which can be used to open youtube, twitter, instagram content in a proxy service. The user shares the link to the app and the app transforms it in a proxied-service link. The proxy instance can be configured. You could point it to a personal instance, or use the public ones.
• all the apps provided by tibor caputa (simplemobiletools). If someone has problems removing the google dialer (not just the call starter, but the entire in-call ui package), he just released an app that works just fine as a replacement.
• slide is another reddit client. It is multi-account friendly and has a lot of customisation settings.
