Calculator Plus with History

Start with the history and memory tools, since the description presents them as the core of the app. You can save earlier calculations, review them to double-check totals, and continue a long calculation later.

Next, add the calculator widget to the home screen so you can run quick sums without opening the full app. If you work on several budgets at once, try multi-window mode, which opens more than one calculator window side by side.

The app covers percentage and tax functions: sales discounts, tax-inclusive prices, tips, increases and decreases, profit margins and markups. A scientific mode adds parentheses, logarithms, exponentials and sin, cos and tan, which suits school homework and algebra.

The app also converts currencies and measurement units, and a days calculator counts the time between dates and works out age. Saved calculations can carry notes, which the developer links to expenses, tax records and budget plans. Digitalchemy has published the app since September 28, 2012, and version 8.1.10 was updated on October 27, 2026.

Calculator Plus with History is free but carries ads and offers in-app purchases, so anyone who wants a screen without interruptions may prefer another calculator.

For plain arithmetic, Samsung Calculator or Calculator may be enough. DayCalcy is worth a look if date math is your main task, while ClevCalc and NerdCalci are other all-in-one calculators to compare.

Calculator Plus with History comes from Digitalchemy, LLC and carries an Everyone content rating. It has been around since 2012, and the current version is 8.1.10. Ads and in-app purchases are part of the free app, so review the permissions and purchase options on the store listing before you rely on it for budgeting or tax figures.
