User Reviews

Users praise Calculate84 as a fast, accurate, TI‑84‑style calculator ideal for schoolwork, with a smooth interface and strong reliability. Many appreciate a free version with few or no ads and solid developer responsiveness. However, several reviews point to intrusive ads in the free version and a paywall that gates graphing features behind a premium tier, which detracts from the experience for some users.

Smooth, fast, and user-friendly with a clean interface.
Portable and reliable for school use; serves as a strong backup/replacement for a physical calculator.
Free version is ad-light or ad-free and the developers are responsive to feedback.

Cons

Ads in the free version are intrusive.
Premium paywall gates graphing features behind a subscription.

When I entered “Ans^-10”, Ans being 1e-1000; The wrong answer this gave me “1e-10000” instead of the correct “1e10000”. I noticed this many more times before while calculating big numbers like that, before crashing. Otherwise, this is a great calculator app, and I hope to see it get better!
