### 1/5 — Downloaded by accident can’t get a refund

*2020-11-11*

Annoying

### 1/5 — Not all settings work ?

*2020-07-03*

When I try to use the ”Distance” option. The app turns off. ??

Need some assistance / app fixed

### 1/5 — Glorified calculator

*2017-02-07*

I needed an app that automatically measures distance and slope. This app does the same as a normal calculator; everything has to be put in manually. Not worth the double digit price!

**Developer response:** Thanks for the feedback.  Many contractors / students / homeowners do not use these types of calculations often enough to remember the formula to calculate slopes, elevations etc.  I designed this app for that specific reason.  I guess, it is a glorified calculator, but I guess you could say that for thousands of other apps on the app store.

I'd like to think the app has a clean easy to use interface that provides worthwhile information to the end user.

I'm not sure of any iPhone device having the ability to measure distance / slope accurately without actually using survey equipment.  Our app is an end user slope calculator just as the name suggests.

### 3/5 — Would be a five if it had a inch input on both measurements

*2013-06-23*

I with you could input both feet and inches into both measurements, that would make this the perfect app. Overall still a good app.

**Developer response:** Something we are working on! Thanks for the feedback.   As a surveyor, our imperial measuring system is the decimal (tenths)... Builders, like you, may prefer the resultant answer to be displayed in feet and inches...

### 5/5 — Site development

*2022-07-02, version 3.3*

I bought this to make quick elevation and slope changes. Works great for in field site work along with structure and pipe elevations. It is a simple calculator that has an algorithm. I love it!

### 5/5 — Surveyor on pipe crew

*2019-01-27*

As a surveyor on a pipe crew I use this app everyday, saves so much time!

### 5/5 — Slope calculator

*2013-01-30*

Fantastic app makes quick easy work of all calculations.

**Developer response:** Thanks for the feedback!
