• Decimal entry uses Blue buttons. Begin repeating decimals entry by clicking the Ṝ button.

• Units of measure include yd, ft, in, m, cm, mm

• π as 22/7 or 'long click' π for 355/113

• Edit equation by clicking the term you want to edit. Then click the equation again to return to normal entry mode.

• Copy equation: Long click the equation. Then paste into a google search to compare / confirm answers.

• Long click in/cm unit button to switch between base units.

• Display your entered fraction, decimal or answer to the measurement screen by clicking the "=" button.

Inch to/from Centimeter:
• Convert answer between inch and centimeter by long clicking the in/cm base unit button in the upper left calculator row. Then click the "=" button.

Memory lists usage:
(top left button of calculator buttons)

• Select the list button to fill the equation (after operator) with either "Saved" or "History" answer values

• If input has an answer, select the list button to "Save"

• Hold (Long click) the list button to clear the "Saved" or "History" list of all values

• History list saves the last 50 calculations

Convert a decimal to fraction or fraction to decimal:
• Converting fraction to decimal displays last 3 decimal of returned value after an ellipse on decimal values of up to 12M in length

• Title Bar configurable to display total length and the repeating decimals starting position.

• Capable of inputting repeating decimals. Repeating decimals are displayed as green decimal numbers when active.

Inch style Number Line:
• Displays an imperial inch or centimeter style number line (not actual size) that updates itself as you input your values (either decimal or fraction). For both negative (increase left) and positive (increase right) input.

• 'Bump to Nearest' Decimal = 0.1, 0.01, 0.001, 0.0001 or Fraction = 1/4, 1/8, 1/16, 1/32, 1/64 and 1/128 or enter your own Custom Fraction Denominator from 1/2 to 1/10000 by clicking left or right halves of the inch style number line.

my neighbors cats ,

Great App!

I’m an electrician and sometimes I have to convert weird fractions and decimals into inches and haven’t found a calculator to do it until now. This one is perfect for what I need and absolutely worth the $2

Perfect for my needs

I build furniture. This app is exactly what I’ve been looking for. It accepts any combination of measurements, whether feet, inches, or metric, and outputs just the same. Very easy to use.

Garbage.

Don’t waist your time

Developer Response ,

Hi 🎤🌵, that is one heck of a brutal review. When developing the app it was never my intention to waste anyone's time. Quite the opposite.

I hope the following response may help your goal of efficiency. If not, I will gladly physically mail you a full cash refund if you haven't figured out how to get a refund through the system. Send me an email of your address. I'm not that way.

There are a few common math app related things the app doesn't do:
1) Show work (such as for homework)
2) Rounding (Precision is more important to me. See more below)
3) Square Roots (Mainly because of rounding. But may in the future return a decimal value as an answer in a rounded value.) Lots of irrational values.


Number input key click usage:

Whole numbers (blue outlined) are on the left half along with the negative, decimal, and repeating decimal start buttons.

Fraction inputs have green outline.
Fraction Numerators are in the upper right half.
Fraction Denominators are in the bottom right half.

Ex:
1 + 1 = 2
2.25 - 1.1 = 1 3/20
1 1/2 - 3/4 = 3/4

A simple click of a number button puts it in to the input at the top. I'm sure you've got that. In the Whole Number buttons you'll see units of measurements(UofM) in the upper right corners.

To put a UofM after a numeric value you'll need to "long click" it(hold it down for a full second). Or a simple click of the grey "return as measurement" button (second from top left) after a numeric input.

So:
8ft 4 1/4in ÷ 4 = 25 1/16in
or
5.54cm - 3cm = 1in

To return a measurement of a different value:
"Long click" the grey "in" button (second from left top grey button).

So now:
8ft 4 1/4in ÷ 4 = 63 527/800cm
or
5.54cm - 3cm = 2 27/50cm

To show a returned measurement (answer) to a visual representation (ruler screen), decimal value, fraction (decimal and fraction conversions), or "rounded" value. Click the "=" button one more time after a returned answer, a single input measurement, a single numeric value, or an empty input.

On the "ruler screen" there are three synchronized things happening.

changing a decimal updates the fraction and ruler.
changing a fraction updates the decimal and ruler.
Clicking the left or right half of the ruler updates the decimal and fraction values.

When dealing with measurements this app does not round an answer. This way I can give an exact conversion between different types measurement. But I do offer the user to "Bump" to the nearest value of their choice.

When in the ruler screen click the "Gear" button at the top right which will give you multiple options (even customizable) to round up or down to.

When you have set what nearest bump value you want. swipe down the popup screen and click the left half of the ruler to go to the nearest value down. Or, click the right half of the ruler to bump it to the nearest larger value.

I leave it to the user to choose what they want. Rounding is what I believe to be a 3rd/4th grade taught function that should be used at the users discretion.

To change the ruler measurement that is displayed. Go back to the calculator screen and "long click" the grey 2nd from left top button to change the displayed ruler.

If you have any questions or even suggestions of improvement please feel free to contact me by email. I'm more than willing to try and help with or improve the app.

Thanks!
Grant T.
