This thread is ONLY to talk about Calculator, Camera and Calendar FOSS apps and too share your best ones and thoughts.

Probably I will do an edit on the lists I made about apps to talk, because I forgot to add some options when I build in my mind the future threads.

If you want to talk about Contacts, SMS and Dialer FOSS apps, is here.

As I said, I will read (and read it) all comments in all threads to build the final megathread. (Sorry for not reply all comments. even though I read everything).

Your opinions about it are CRUCIAL and FUNDAMENTAL, because your opinions is the main-base to build the megathread.

Have a nice day for everyone. (and sorry about my english, I hope everyone can understand me)
