User Reviews

CALC Smart Calculator ± is lauded for its feature-rich capabilities, built-in unit converter, and convenient UI elements like widgets and Siri integration. It has many long-term users who value its depth and reliability. However, a prominent recurring issue is the switch from a one-time purchase to a subscription model with repeated prompts. Some reviews also note post-update regressions in UI/UX and performance. Overall, the app remains powerful and versatile, but the subscription approach and update-related usability concerns are the most-mentioned drawbacks.

Pros

Rich feature set beyond a basic calculator, including scientific functions, conversions, and an extensive formula/table resource.
Built-in unit converter for quick unit calculations.
Clear, editable input with visible expression as you type and easy error correction.
Widgets and iPad multitasking support that enhance workflow.
Siri integration for voice calculations and a polished, user-friendly UI.

Cons

Subscription model introduced after a one-time purchase, with repeated prompts to pay.
Post-update UI/UX regressions and performance issues (e.g., laggy widgets and keypad layout changes) that degrade usability.

Recent reviews

I purchased this calculator and have enjoyed it for years. It was advertised as one-time purchase. Now with the latest version it is popping up a subscription authorization screen every time I press the equals button asking for a subscription. It has also disabled a lot of the unit conversion functionality. You can’t offer a product as a one time purchase and then years later after the sale come back requiring me to pay you more money. If this is not resolved soon I will delete the app and never purchase anything else from this developer. UPDATE: this has been fixed and is no longer requesting a subscription. Thanks for fixing this. I will update my review.

After recent update there are CONSTANT popups reminding you to give the devs money for a calculator even AFTER you bought it. They made the widget super laggy too, it just gets worse and worse with every update.
