User reviews

Very useful

App is very useful but seems to be forgotten about as far new features being added. As another review stated a percentage would be super useful and to be able to rename the custom selection too.

Decent app but lacking functionality.

This app is cool but I’m a little confused what the point of the changeable units is. Seems like a β€œfeature” for the sake of having one.

A feature that is needed is the ability to compute values outside of the set range. For example, converting a 3.5mA value to counts on a 4-20mA scale. A lot of troubleshooting involves out of range values.

Great App!

This app is fantastic!
Wonder what your thoughts are on adding what the 0-100% value would be.
Ex: 0-100β€’c 16mA would be 75%. This example is very easy but say we’re looking for 42% of the range. Hope this makes sense.

Works well

Quick and easy. It considers all the process variables units. Looks hot. Makes my job so much quicker. Rad.

Response from developer

Thanks for the review!

Simple and easy

I think it would be helpful if you added the math formula with it.

Response from developer

Will look at adding the formula in the next update. Thanks for the feedback
