Free version unusable – Calculator₊ Review

I bought this app years ago for my iPad. Loved it. Since the latest IOS it wouldn’t open, error msg said needed to be updated. No update ever happened so I deleted it and downloaded the free version. That is totally unusable because of the ads and pop ups! In the middle of using the calculator, an ad box pops up or I’m redirected to a website I didn’t ask for! I refuse to buy an app twice. Epic failure!
