Worked Great on Snow Leopard, but won't work on Lion!!!! Update it Already Dev!!!
App~Guru
When I had Snow Leopard this app was great to keep my Macbook Pro's Battery "calibrated"(basically doing a full battery drain once a month", but since I've installed Lion(Since its release in July) I can't get this app to work. The app will "load" on boot, but the menubar icon is no longer there, rendering this app useless since you can't control it or check "calibration" or get reminders without the menubar icon. I gave the Developer several months to come on board with Lion, but considering it's almost 5 months since Lion's release and no update has been provided this app is now useless and the Dev seems not to care. DON"T BUY THIS APP IF YOU HAVE LION!!! IT WON"T WORK!!!! DEV UPDATE THE APP OR REMOVE IT!!!!!!!!!!!
Extremely disappointing. Save your money.

Had used this for a couple of years prior to Mountain Lion (downloaded from the developer's site) and found it very useful. Since Mountain Lion, however, the application refuses to appear in the menu bar, which renders it useless. Support has been poor, with extremely slow responses, and the soluitons have amounted to providing me with codes to download versions from the App Store, which don't work either. Considering the rather limited functions it provides, it seems overpriced in any event, assuming, of course, that it works. In Mountain Lion, for me, at least, it's just an expensive icon and pointless splash screen.
Doesn't work in Mountain Lion

when ever I start or restart the mac the welcome screen shows but the icon never shows in the menu bar. Watts support has not responded to any of my requests for help.
So far not impressed

Purchased this program mainly for the battery calibration/conditioning function. Layout it nice unfortunately once you get to step 2 the timer function gets stuck at 1:45 minutes. past that it won't count down. As a result you can't go on to the other steps. This makes for a not very functional product. As is I would not recommend. If they fix this I would.
