About this app

🎁 The Pro version of the calculator is now free!

ATNSOFT Calculator lets you:

✓ Instantly enter numbers and mathematical expressions using an ergonomic on-screen keyboard and voice input (currently supports English, Arabic, Bengali, Chinese, Croatian, Czech, Dutch, French, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Malayalam, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Tamil, Thai, Turkish and Vietnamese). Just press the mic button and speak the expression (for example, 74 point 5 times 4 plus 37 = 74.5 × 4 + 37 = 335): it will appear on screen and the result will be calculated immediately!

✓ Make two or more calculations simultaneously. To do this, you can switch editing screens with a horizontal swipe along the top edge. You can give names to screens by tapping the screen number.

✓ Quickly copy the result to the clipboard simply by tapping it. There is a special button for pasting from the clipboard (📋).

✓ All calculations are recorded in the calculations history, from where you can insert the expression and result into the editor. These records can be instantly deleted with a horizontal swipe. Any record from the history can be tagged with text by tapping the date or time.

✓ Execute mathematical operations with incredibly large numbers and expressions.

✓ Raise to the n-th power or extract the root of the n-th power (for example: 5 cubed = 5^3 = 125; the cube root of 27 = 3√27 = 3).

✓ Percentage calculations (for example: 200 + 10% = 220; 10 % 200 = 20).

✓ Convenient, user-friendly settings that can be easily opened with a swipe right on the keyboard. The settings include: vibrate on click, full-screen mode, keep screen on, and other options.

✓ The result is always displayed naturally, without incomprehensible E's, dashes, and numbers.

✓ Easily work with many memory cells, and easily switch between them. You can set a name for each cell, letting you intuitively use the memory for a specific field of activity.

✓ Quickly switch themes.

I was looking for a calculator app better than the ones from Samsung & Google — and this one is amazing! I love that it has a voice input button, so I don't need a separate (second) voice calculator app! I also love that it has several calculating screens so you can do several operations at once without clearing out the screen. Superb app! 👍🏼👍🏼⭐⭐⭐⭐⭐

This calculator is accurate in voice recognition and entering the correct numbers called.. but if I want to add a series of numbers for a final sum, I have to talk non stop at high speed without any break, or it interrupts me with an equal sign, before I am finished. and I have not said the word equals! Only the word "add" between the numbers. This is ridiculous. Needs more work to correct this fatal flaw.

App user is visually impaired. It works perfect, no issues, no crashes, doesn't delete what you are working on if you close the app. No intrusive permissions or ads! Update wishlist: bigger font for equations and answers, spoken results like tapping the answer so it will speak it, fractions "3/4+1/2=1.25" would love the option for it to have "3/4+1/2 =1 1/4" would replace a dedicated fractions calculator I use.
