    Do not download. Repeat, do not download the current or future versions. The comments explain that this app was recently "upgraded" by new owners to include a caller ID. Can only wonder what else is included or what they do with the numbers they ID. It is possible to not give permission for this, by adjusting settings in the app - or maybe that only hides the visible pop up adds that appear before the calls you get. Guess the ads revenue from those in the actual calculater weren't enough. All and all, some pretty evil businesses tactics hidden behind a mediocre calculator. Don't waste your time.

    This used to be a very good calculator, but it has been bought by Appsbuyout / Sappalodapps, this is a company that buys apps and then fills them up with crapware. Fortunately I still have an old version, I keep that and never "up"grade.
