Spark
The one Email App that made me from not seeing trough my emails at all, to managing all of them easily. I can only recommend it. Is also available for almost all other platforms, except Linux :(
HiPer Calc
Really good calculator, that can also do a lot of scientific stuff (Matrices, plot Graphs, solve for values, etc. Everything I needed in maths at university). I study and teach maths and it is really great for both.
Calender
I have all my events and schedules in the standard Samsung Calender App. Sadly they are spread on various accounts and some only saved locally.
If I could save them all in one place would be great, since if I look up my Calender in for example my computer, I cant be sure if everything is in there.
I have a huge calendar widget with a monthly and listed view on a side of my home screen, which is very useful.
Quillpad
My current go to Markdown Editor for Android. I would like to switch to Obsidian to have everything in one place, but not the case yet.
Firefox
Use the install or whatever called feature to have websites as app like Icons on your homescreen. Very useful. ๐
Feem
Transfer Files between devices quickly. I would be glad for open source Alternatives, but I am mostly settled on Feem now.
PDF's
I have a few Apps for opening and viewing PDF Files, which is really useful. That way I can open different Documents in each and switch between them very quickly.
I also use the Zoom and Moodle App, since I am a Student and they are ok.
I like the Samsung Calendar (especially the widget) more. The main problem is that I dont know how to move all my calendar events to for example Google.
