User Reviews

Users praise Calculator # for its robust scientific/graphing capabilities, ease of use, and substantial free features. The main recurring downsides are an intrusive ad model with full-screen, autoplay videos (often with sound) and upgrade prompts. Some users report reliability issues (incorrect results, equation errors) and occasional performance problems on older devices. Despite ads and glitches, many still find it useful and versatile for math tasks.

Pros

Offers scientific/graphing calculator features beyond the built in iOS calculator.
Easy to use with an intuitive input method.
Many features available for free without needing to upgrade.
Useful for math work and high school level needs; versatile tool.

Cons

Excessive ads and intrusive ad model including full screen video ads.
Ads can play with sound and interrupt calculations and meetings.
Reliability issues such as occasional incorrect results and equation errors.
Performance problems on some devices or after updates including freezing.
Pressure to upgrade to remove ads, making users feel the app is monetized greedily.

Recent reviews

Used this calculator app for 9 years cause Apple's basic app at that time didn't have scientific functions. It was great until developer got insanely greedy just within the past year. I didn't mind the banner ads, those were around since the beginning and they gotta make some money. Then dev decided to add a timer that autoplays a video ad on your entire screen every 4 minutes the app is open! If that wasn't obnoxious enough, it now plays a video ad if you let it sit for a few seconds after EVERY SINGLE CALCULATION YOU DO. That did it for me. Thankfully, it seems that years later Apple has finally added a scientific calculator to their calculator app so I won't be needing this one anymore.
