History Calculator Plus

A simple calculator that shows the whole formula as you type, and keeps every calculation so you can bring it back.

See your formula

• The whole expression stays on screen, so you can check it before you press "=".
• Made a typo? Move the cursor with the arrow keys and fix just that spot.
• The answer is previewed under the formula while you type.

Bring back past calculations

• Every calculation is saved in the history list (the latest 200 are kept, even after you close the app).
• Tap a formula to bring it back, change a number and calculate again.
• Tap an answer to insert it into your new formula.
• "Ans" puts the previous answer into the formula. Start with + × ÷ to continue from it.

Everyday math

• Add, subtract, multiply, divide and parentheses
• Percent: 50% is 0.5, and 200 + 10% is 220
• Good for shopping, splitting bills, budgets, homework and work

Notes

• Your history stays on your device and is never sent anywhere. You can clear it from the menu.
• Ads are shown at the bottom of the screen.
• You may be asked for consent about ads when you first open the app. You can change your choice any time from "Privacy settings" in the menu.
