### 5/5 — Best app for mechanical engineers

*2023-11-25*

As an engineer I can say that this app is have for all mechanical engineers!

### 4/5 — Great app, but need to be updated to 11 iOS

*2018-01-22*

Great app, but need to be updated to 11 iOS

**Developer response:** Hello,
Thanks for using Mechanical Engineer,
We are happy to let you know that Mechanical Engineer has been completely rewritten and supports the latest iOS!

### 3/5 — Need ios11 update

*2017-12-11*

This is a great app. Would have rated it 5 stars but with the new ios11 update I can no longer open this app. Hopefully there will be an update soon.

**Developer response:** Hello,
Thanks for using Mechanical Engineer,
We are happy to let you know that Mechanical Engineer has been completely rewritten and supports the latest iOS!

### 3/5 — Update for iOS 11!!!

*2017-11-22*

Yeah, please, since this is much more convenient to use than the alternatives.

**Developer response:** Hello,
Thanks for using Mechanical Engineer,
We are happy to let you know that Mechanical Engineer has been completely rewritten and supports the latest iOS!

### 3/5 — Metric Units

*2017-08-23*

This would be very useful if it was produced in metric.

### 2/5 — It's ok

*2012-03-19*

It works well, but I wish it listed what the units are for each variable and answer and it would be nice to be able to see the equations. If I knew what it was like before buying it, I wouldn't have wasted the money.

### 1/5 — Could do better

*2012-03-01*

I have to agree with the first review.
No ability to change the units, and no formulas.
Hopefully there will be an update, until then this app is of no use to me.

### 3/5 — Ok but I expect more from a pay app

*2011-05-31*

Great selection but only useful for education if it has the actual formulas. Would be great to also have more information on units required, or even better the ability to enter in the units you have available for each variable and have the app do the conversions. After all the point of a computer is to compute!

### 4/5 — Almost got it

*2011-05-24*

I feel this app has many good things in it.  The lack of easily understood units when entering values was the only bad part about this app.

### 2/5 — Incomplete

*2011-02-19*

Lacks GUI. Will not operate within a variety of units.

**Developer response:** Hello,
Mechanical Engineer has been completely rewritten from the ground up.
Please let us know if you have any feedback: support@multied.com
