About this app

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, 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 opened by swiping from the left edge of the screen or using a menu button. 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.

Important: For voice input to work without the Internet, the appropriate voice baselines must be turned on in the Android settings. However, voice recognition is more accurate and higher-quality with an internet connection.

If voice input doesn't work, then in the Android settings select: Language & input > Voice input > Basic Google recognition.

Replaced my default calculator and I can't imagine anything replacing this one. All the features I've used, including voice, have worked wonderfully! I love that I can name each window, and I love being able to view a calculation history. If I had but one suggestion, it would be great if I could see at least 2 windows simultaneously. Thanks for a marvelous 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.

First calculator to work. All the other ones only add two different figures at a time and they don't even work properly. This one worked and it added a full 25 in verbally. You can stop and let it calculate and it does it quickly and then you can just press the voice button again to continue with the same calculation. It's awesome. It does exactly what it's supposed to do and it's the only one I found that does.
