Calculator PRO Customer Insights

1. A needed function is the silver feature which will help me out to speed things up in quickly getting a general picture of what's happening in applications, and an exact accurate assessment if and when desired.This app causes full screen pop up ads to constantly appear on your screen (without warning, didn't mention it during installation.

2. Also when you try to multiply something by the answer its cuts it off from the screen.This app may seem useful at first but that quickly changes once it installs adware on your phone.

3. but ofcourse the graphing calculator is super expensive,this is freeapp itself worked fine, however a day after installing it my phone was riddled with ad popups even when not using the app.

4. Needy, much? Second thing - when it displayed the answer (to a ludicrously large number of decimal points) it did it right-justified, so the important digits were way off the left hand side of the screen.

5. I've been thinking it was other apps and almost reset my phone until I read others having issues with this app in the reviews.

6. Adware examples i had are phone cooler, drink water, phone security and medical/college ads.This app brought a virus of sorts onto my phone.

7. The adware pops up and covers the entire screen making you wait up to five seconds before you can close it.

8. Delete this to get rid of adware that has been affecting you ever since the calculator's installation.

9. I know it was this app for 2 reasons: 1) after an add would pop up I would look at "recently opened apps" and this would be #1 even though I hadn't manually opened it in days & 2: the adds stopped after uninstalling.

10. DON'T DOWNLOAD!!I just stumbled onto this calculator and I am a math student in second year of college, its excellent, just what I needed.

11. Clicking recent apps will show the adware "hiding" in your installed apps.
