There are no instructions on how to enter a fraction. The help button lead to a YouTube video on the settings, which is nice. But zero explanation on how your buttons work, or how to do a basic conversion. BUT, on the plus side, I have hopes that your app can do what the other calculators can't seem to do: Be useful. I just want to convert between Imperial with fractions, to Metric with decimals. Like a simple measuring tape.

A well deserved 5 stars, a high quality and well thought out app that saves the conversion headache and time, simply click on any variant mode of measure and it shows it in that mode, and also any other mode, and calculates and adds different measurements (eg) inches AND cm AND feet AND yards (plus more) all in one calculation. No need to standardise whilst typing - the app does all the work.

Video doesn't match the app - there's no MR (memory recall) button on the current app. I gave it 10 minutes of trial and error, and I can't figure out how to recall the memory, which makes it unfit for my use. Moving on!

Since a few days ago, there's a vibration with every tap. This literally drives me crazy. I can't find a way to stop it. This app was great, 4-5 stars, now I might be getting rid of it. This will be 1 star and removed without correction by the end of the week

Currently bugged and results in being mathematically incorrect. I multiply inches by any number and it converts it to feet, when the resulting number should be less than a foot. Square root also does not function with fractions at this time.

Used to be great, now mathematically incorrect, add 1/16" and it adds a full 1/8" please fix. Used this since it was originally made

Ads are so annoying and even if you disable this apps permission to use wifi and data, it still accesses it.

Not a construction framing calculator. ad pops up first time you push a button.

A really good construction calculator I'm building a geodesic greenhouse and it has been very useful!

Calculating fractions simply doesn't work and there's no help.

Pau. M. Oct 15, 2021     

I like it very much. Very practical to use on site and in class.

Ter. D. Dec 5, 2020     

Great app. I don't have to look for a scrap piece of wood to calculate.

Looks okay but unable to find metric conversion

Ben. M. Jul 20, 2021     

How come i can't count my concrete volume in feet and have a meter volume anymore, i work in imperial and order my concrete in metric, must be like that in all North America, please gimme back my app

I use on daily basis and makes my work a lot easier.

Sal. S. Jan 10, 2020     

Good app, hope to provide the arithmetic calculation to convert between Pressure units eg.. (1255lb/sqf ) / 1Pa = ✓✓

Rud. H. Aug 23, 2020     

I'm sad to report that if one lives in a metric world this app comes up with rather strange and wrong calculations. A pity!

Actually use for mechanics work on my vehicles; love it 😀
