This calculator app lets you see formulas as you type them.
Once a calculation is complete, your calculation history is saved and displayed in a list directly above the input field.
This allows you to view your history without switching screens.
Eliminate calculation errors and easily review and edit your history.
You can also include discounts and taxes, making it ideal for a variety of purposes, including everyday shopping, expense calculations, accounting, and travel planning.
[Key Features]
📝 Formulas and History at a Glance
Formulas are displayed in real time as you type, allowing you to instantly check the answer.
When you confirm a calculation (=), the formula and answer are automatically added to the history.
Always see the entire calculation by simply scrolling up and down. No need to take notes or switch between screens.
🔗 Answer-linked "Quote" feature
Tap an answer in the history to quote that number into the current formula.
If the answer of the source formula changes, the result of the referenced formula will automatically update.
(Example: 100 + 100 = 200) (If you quote the answer to this calculation and later change the original formula to 100 + 200 = 300, the value in the referenced calculation will automatically change to 300.)
This allows you to use it like a simple spreadsheet.
✍️ Avoid "What calculation was that?" questions with the memo function.
Add notes to each calculation history.
By recording entries like "Lunch Expenses" and "Company A Transportation Expenses," you can accurately recall the purpose of a calculation when reviewing it later.
🔍 Powerful Note Search
Search for memo contents by keyword across multiple calculation lists.
By adding specific terms like "July Business Trip" to your notes, you can quickly find related calculations later.
