• Terminal: termux is the best, just don't use the google play version, it's outdated. Just use the fdroid version.
• EBook Reader: I've used most of them, I really like KOReader for it's built in calibre functionality.
• file sync: syncthing full stop.
• file sharing: Warpinator if its your own machines, otherwise go to pairdrop.net
• IDE: Acode on fdroid is probably the best mobile-optimized one I've tried.
• Backup: Titanium Backup is probably still the best option for backing up appdata.

Hope this helps!
