I'm using Mort's music player,
FX camera
lightning bug alarm clock
ACV comic viewer (for .cbz e books)
Barcode Scanner (it's cool cause you can scan a 3D barcode on your comp screen and it'll take you to the download for apps)
Ascii camera
Call Confirm (stops unintentional calls)
Sparks (like a plasma ball on your screen, for fun)
Stopwatch (basic stopwatch)
Tone Picker for setting ring tones and alarms to different mp3 files.

plus the preloaded apps. and google maps. everything I downloaded was the free versions.

honestly I don't use most of them often. I like the FX camera though. and Mort works well for me.
there was another music app I had with an EQ I liked, but it crashed once so I tried Mort and it hasn't crashed.

I guess all the apps don't work equally well on various hardware, and I have the "sence ui" version of Android to which is a bit different than yours.
