Since launch in 2008 feedback from users has been the most influential factor in SketchAndCalc’s development. An area calculator with surprisingly endless uses from a wide variety of industries sometimes makes it difficult for me, the developer, to prioritize which features offer the greatest return for most users.

## Unusual uses of an Area Calculator

**I’ve been contacted by users all over the world who are using SketchAndCalc™ in ways I couldn’t have imagined. Some of the more unusual uses have been:**

A group of Australian hospitals performed a medical study to compare skin ulcer healing rates, and arrive at the optimal treatment strategy.

An electronics engineer needed to calculate the area of silicon in nanometers.

A spinal surgeon needed to compare the length of the posterior longitudinal ligament when in flexion, neutral, and extension positions.

A research scientist needed to find the area of multiple foci (cells) in an image to determine their total volume.

## Feedback

**Feedback from users has helped me choose which features to build, as well as inspire me when things go wrong. Here’s one that stood out:**

*Hi Elliott *

*…THANK *YOU* sir*

*The efficiency of this app has literally placed me ahead of my competitors.*

*To date, I have been completely accurate and have cut my costs on orders!*

*As mentioned I personally use your app *EVERYDAY* and recommend it within my sales and construction divisions.*

*Please pass our correspondence onto everyone *involve*. And a huge thank you for the awesome app*

*Regards*

*Darren Nienaber *

## How is SketchAndCalc helping you?

**With feedback from users on why they are needing to calculate area being so important, I’ll be routinely posting answers to this question below.**

It is helping me complete my Research Practicum Project, and allowing me to calculate the area under my graphs so that I will be able to determine which brand of carbonated water is of the highest quality.

SketchAndCalc helps me with calculations for my interior design renovation project. It calculates area and perimeter of multiple rooms and floors from PDF drawing.

Helps estimate areas that are completely out of the ordinary in shape. With normal methods, this estimate would be highly complex, but this software makes it super easy to run.

There are many ways SketchAndCalc has helped me, that’s being more productive, more efficient and more precise in measuring and in creating projects for my colleges.

As a part of a small expanding interior design business this has helped us provide exact flooring measurements on difficult plans and layouts, therefore, making our lives simpler and our customers happy.

It helps me a lot when computing the area of the lands here in our place. Especially when the lot has an irregular size. No need to do long methods of computations.

I enjoy being able to calculate areas based on scanned images. This makes it easy to calculate specific areas for maps, without having to figure out irregular areas by hand.

I am working on a project for estimating % wound coverage on injured animals that come into rehabilitation hospitals in an effort to better assess prognosis on intake.

I am able to measure roofs with this tool, even roofs that have very atypical or irregular shape too them. So cool! I highly recommend using this app for myriad reasons.

It’s helping me calculate the land size of properties, it can be very tricky to calculate irregular land sizes using only math. Your program speeds the whole process up!

We are working out the length of a fence from a photograph and seeing if SketchAndCalc can do the job! It saves the hassle of having to measure out in the rain!!

This program helped me a lot for the project that I am doing which require me to calculate the irregular area of a foot. It is really easy to use and does not require a lot of time to learn all the features.
