The best apps for you are the ones that are best
for you. If you're an astronomer you won't care about carpentry calculation apps. If this is your first Android phone, look on the Play Store - just spend days looking through all the free apps, install what looks interesting, uninstall what you don't like. I use
App Backup & Restore to back up anything I may want to install some time in the future, but don't want taking up space now, and
Helium to back up the data from apps that don't have their own data backup that I can copy to a computer.
But you're really on your own unless you give us some clues.
