[Main Features]

📝 See Your Formula and History at a Glance

See your current equation in real-time and check the answer instantly.
When you press equals (=), the equation and result are automatically added to your history.

Simply scroll up or down to see your complete calculation overview at any time.

🔗 "Reference" Function with Linked Answers

Tap any answer in your history to insert that value into your current equation.
If the original equation's result changes, any calculation referencing it will automatically update.
