Comparison
A Desmos alternative that shows its working
Desmos is an excellent plotting tool and it is free, which is not in dispute. It stops short of explaining itself — and that is the gap this calculator fills.
Where Desmos Is Stronger
An honest read before anything else
Desmos is a polished, well-engineered graphing environment. It is fast, its syntax is forgiving, its classroom collaboration features are excellent, and its free tier is genuinely free. If your need is purely "plot this accurately and share it", it is a very good choice.
It also has a much larger user base, which means more tutorials, more shared activities and more answers to your exact question already online.
Where This Tool Is Different
Two specific gaps
It explains itself. Every result here arrives with the reasoning attached. If you want to know whether your method was right — not just whether your number matched — Desmos does not help you, because it does not expose its working.
It uses the TI-84 keypad. The layout matches the handheld you were taught on, so you are not relearning where anything sits. If your course uses a TI-84, that continuity is worth more than it sounds during a timed problem set.
