• Music player: "dialog music player" for filemanagers, Vanilla music if you want auto-play, anrimians player is nice too (github)
• maps: nothing beats OSMAnd
• Notes: personally markor, but if you want cross platform sync Standard Notes may be nice
• Keyboard: Florisboard forever, so stable and customizable. I cant like without the internal clipboard and quick deletion, and the editing buttons

Joplin

I sync it with onedrive basically for free between my phone, laptop and computer. It's wysiwyg editor means it was basically a drop in replacement for EverNote for me, but open source and without the costs.

Wildcard for keyboard: ThumbKey

This has been pretty great, although unique.

What's the best alternative to Gboard?

I've gotten use to swiping to type, and the English (Australia) (PC) QWERTY layout with the number row at the top, and hold-press numbers are the equivalent QWERTY keyboard symbols.

Am finding it hard to replace.

Fcitx5 supports CJK

I've been using Minuum for years despite it being long abandoned by its closed source devs. Fans of this very unique keyboard would love to have an OSS alternative!

For music, I use FinAmp. Basically have self-host JellyFin and can stream the music over LAN w/o using storage, or download it to my phone for offline listening

Ty everybody for all comments!

And being anoying again (sorry about that), if you can share your apps ideas on previously threads (they are on this main post), I appreciate :)

Notes:

I don't like that most notes apps don't let you access to your files, relying instead in cloud synching. One of the few that gives you full control is https://f-droid.org/en/packages/net.gsantner.markor/

It let you chose a folder where to save your notes and can manage many types of files (markdown, txt, todo, csv, etc)

I like saving my notes on my SD card, I created different folders to work as notebooks, so for example, I have a folder named "comments" where I edit my comments before posting, one for lists, one for lyrics of songs I like and I'm thinking about making one for cooking recipes.

Music:

https://f-droid.org/en/packages/com.poupa.vinylmusicplayer/
https://f-droid.org/en/packages/player.phonograph.plus

and https://f-droid.org/en/packages/ch.blinkenlights.android.vanilla

Are the best for offline experience. I really like vinyl's and phonograph's plus UI, simple, yet powerful. Both supports lyrics, metadata editing and at least vinyl can connect to the internet to grab artist picture and bio which can be displayed offline, I'm not sure if phonograph can since it's main focus is privacy and to work fully offline.

The issue i have with both is that they don't work properly on my Samsung tab, I think is the awful Samsung bloatware that makes them stop, and not make full use of all their features.

Vanilla UI isn't the best looking but it has many features when combined with the extensions. The best Foss metadata fetcher and editor. The problem the app have is that it isn't update frequently, and at the moment it has a problem with the notifications. There's already a PR opened in github, so hopefully this get fixed soon.

Keyboard

I'm currently using 2 keyboard apps https://github.com/Helium314/openboard as my main and https://f-droid.org/en/packages/rkr.simplekeyboard.inputmethod When I'm tire of the autocorrector changing what I write. I know I can disable it on openboard, but most of the times I actually use it and simple board is just more fluid.

Keyboard: AnySoftKeyboard and Unexpected Keyboard
Notes: Joplin

Hacker's Keyboard is the only keyboard app I'll accept on Android.
