### 1/5 — Joke!

*2025-03-24, version 3.1.6*

This is nothing but a list of recommendations! Doesn’t calculate anything that anyone who SHOULD be working on can’t quickly solve on their own! Don’t waste $5 unless you are too lazy to use an internet search!

### 5/5 — Time saver !

*2021-11-15, version 3.1.5*

Wow ! All informations I need in one app ! I feel like I can build anything! 💪🏻

### 4/5 — Helpful app but missing a key function?

*2021-01-17, version 3.1.3*

Unless I just can’t locate it within the app, you may want to consider adding a sensor function for measuring lengths. Granted, iPhones have this capability built-in (not sure about android devices), but that requires switching back and forth between your app and the iPhone measurement function, which is a nuisance considering that this: A) is a “paid app,” and B) is a *basic function* that one would expect to see in an app of this type.

### 4/5 — The more I use it... the better I like it!

*2020-07-24, version 3.1.3*

I really like this app.

The only reason I awarded 4 stars was because,  and this may be due to my ignorance, I would like to be able to save frequently used calculations / conversions to a "short list" rather than having to use the menu.

### 5/5 — Wow!

*2020-06-09, version 3.1.0*

This tool is amazing.  Has definitely saved me time and errors!  Definitely a great addition!

### 1/5 — Material estimator

*2019-07-26, version 3.1.0*

Unless I can’t figure out this app since the update it has no place to estimate how many tile needed for a job

### 5/5 — Love this app.

*2019-03-24, version 3.1.0*

This thing is great.

### 5/5 — Great app

*2019-03-09, version 3.1.0*

Great app for the home owner or DIY

### 5/5 — Best app for estimating cost

*2019-02-26, version 3.1.0*

This is the best app I have found for do it yourself projects it helps you calculate the materials you’ll need and even some cost it helps you figure out sizes and materials needed for the projects it comes in handy especially when you’re at the hardware store looking for the materials you need to tell you how much you’ll need of that material and how much material you might be needing

### 5/5 — Very nice

*2018-11-04, version 3.1.0*

Great app for newbie contractors or ones who’ve been out of it for a while. In estimating installing flooring could you include installing floating laminate floors including using water-proofing with adhesive sealing in addition to under lament types. Thank you.
