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.

Recent reviews

Why are there advertisements? No one who uses this app is going to see an ad at the top of their screen and go buy a box of ritz crackers. There's no point. If you want people to buy the stuff. Show it when you show them the premium for 2.99 a month.
