### 2/5 — Annoying Amount Of Ads

*2026-08-18, version 4.1*

It feels like every two or three equations I enter I’m hit with 3 ads that take several seconds to skip. The calculator itself has great features, and I don’t mind ads here and there, but this is wayyy too many.

### 1/5 — Adds

*2026-08-16, version 4.1*

Adds after every question

### 4/5 — WAY too many ads

*2026-08-11, version 4.1*

The calculator works great, but there’s an ad every 10 seconds, so it’s almost impossible to get any work done

### 1/5 — No option for restoring purchases

*2026-08-06, version 4.1*

Despite paying for this app, I cannot get the pro version without ads on my iPad.

### 1/5 — Ad spamming mid calculation

*2026-08-06, version 4.1*

I have used this app extensively over the years but recently every second calculation mid typing it… I get a stupid ad I cannot instantly skip… and afterward, the next calculation it’ll pop an ad before showing me the answer… yet another unstoppable one… DISASTROUS!!

### 1/5 — Was useful

*2026-07-24, version 4.1*

Now it is all of the ads all of the time. Don’t buy.

### 1/5 — The ads are ridiculous

*2026-07-24, version 4.1*

Full screen unskippable video ads will interrupt your every calculation, no matter how basic. Genuinely annoying, would recommend one of the millions and millions of other calculators in the world over this one.

### 2/5 — Ads for calc blows

*2026-06-16, version 4.1*

It is ridiculous that I have to have ads to use a calculator! This is more of a complaint on Apple than this app,  however, as Apple got rid of the free calculator that used to come on the iPhone.

### 1/5 — Piece of *******

*2026-06-06, version 4.1*

Adds crash it every five minutes and you can’t close them even when their done play, app is trash

### 1/5 — Horrendous

*2026-06-01, version 4.1*

You will be bombarded by ads after every calculation, it makes the experience horrible. I would so much rather have a static banner ad at the top then have to wait for the video ad to play every single time
