Too many duplicates... 

There can be only one, or maybe a handful of 20+ utilities in one app that you need. Sadly, this isnt one of them.
I havent tried Appzilla but after this app, it can only go up from here.

The voice reader is OK but theres no voice web browser like that other multiple function $0.99 app I cant remember. The talking tip calculator (which I did own separately) is nice for splitting the bill but theres no calculator or field for sales tax (if youre in to that). 

The unit converter is laughably bad. It seems like its only there to say there is one. Its more like unit converter lite.

I still have this app on my 3gs for now, but I had to re-add AppBox Pro because I needed a useful unit converter, not one for decoration...
