## Most critical reviews (6 lowest-rated)

### 1/5 — WHAT-A-WASTE

*2010-02-20*

DON'T WASTE YOUR TIME NOR MONEY....

### 1/5 — Disappointing

*2009-07-23*

More of a toy than a tool!

### 1/5 — Lacking a lot

*2009-03-24*

The other reviewers say it all. For a 9.99 application I expected a lot more. Will not calculate amps of a 1phase 3000w circuit. A lot of frankly useless formulas that a typical contractor/builder will never need or use. Perhaps there will be improvements in future updates.

### 1/5 — I'm kicking myself!

*2009-03-01*

The format stinks. It's mostly full of unorginized and repetitive conversions.

### 3/5 — its getting beter

*2009-06-03*

It should have a formula for box fill (how big of a box you need for how many wires)

### 3/5 — Uhm!

*2009-04-26*

I can tell a carpenter didn't consult on the design. I wish there was a way to enter tape measure readings to decimal feet. Example. 15' 3-1/16th" to 15.xx feet.  When figuring concrete and building it is vital to be accurate down to the 100th and some cases further. 

I would also like to have the option to covert back and forth from feet inches yards psi on screen so I wouldn't need to change formulas. 

It is a good start and can be handy in the future. Good thing I have a carpenter calc in my bag. With the right tuning this could be a great tool on the job. 

Also the way the numbers are displayed can be confussing for me. But then again it could be converting from decimal feet back to tape measurements and calling it back over the radio for the saw man or the office can make it hard to use for me. If I could do it all in my head I wouldn't need the app in the first place!
