No idea if it works, as an ad pops up every time you start the app. There is no 'x' button to close the ad, and you can't hit the 'back' button to close it, either. The only way to close the ad is to close the app, so I uninstalled it instead.

Absolutely excellent app, only spoiled by persistent reminders to "rate" the app. Why not wait until after I have completed a calculation so I don't risk forgetting information in need too input.

works very well and I'd easy to use. Don't like the " Your phone is infected" adds.
