Battery Dr. Dolittle
I once had a fantastic version of this or similar; however, this version is not as reliable or trustworthy as the predecessor in my opinion. This particular application does not provide real-time charging status but does provide you with a repeating offer to view or purchase other applications. This is a serious annoyance and personally I find it irritating at best in light of making purchase of this - on the free version, perhaps but not on the purchased version – come guys shake your collective-marketing heads and come out of the dark-ages!
