### 5/5 — Eventually, the calculator was put back in

*2019-04-29*

That was the reason why I hated that one update. But they added it back in shortly after that. I apologize for not updating my review to reflect that this app is back up to Par. I find myself using this 3-4 times a day!

=====> Previous
Calculator function has been totally excised from this app- DO NOT UPDATE. Stick with previous version.

I have no idea why developers would make a useful app and then remove that which makes it useful.

Do Not waste money on the "remove ads" iap, unless you delete this crapapp and reinstall version 1.1.

-------------------->

This conversion app has an unprecedented amount of units that can be converted between. Imperial/Metric but also electronic values and data values, plus many others.

And it's totally worth the 99 cents to get rid of ads.

### 5/5 — So useful!

*2019-01-12*

Brilliant and simple to use. 
Don’t know how I managed without it.

### 1/5 — Hopelessly complicated...useful for ticket scientists

*2018-06-22*

Or quantum physicists

### 5/5 — Bug with Customized List Order

*2018-04-09*

The best converter app out there. Inputting for one unit shows results for all other units instead of having to select one unit for another unit. 
I paid for the ad free upgrade -- totally worth it for the value I get out of it. And you should too (or just buy the pro version to begin with). 

Support the developer of this great little utility. I reported a bug after an update, and he was super responsive.

**Developer response:** This should be fixed as of version 3.4 . Please let me know if you are still having issues by sending a note to support@cidersoftware.com

### 5/5 — TomO

*2017-09-03*

Need conversions in pressure to have inches of water and inches of mercury

**Developer response:** These units have been added to the latest version 3.0.  Thanks for your suggestion.

### 5/5 — Brewing Science

*2016-04-07*

This is the perfect app for my Brewing science course!

### 5/5 — Excellent

*2015-03-07*

As an engineer it is necessary to say this app is the best one that I have ever seen. Very simple fast and complete. Thanks for such a useful application.

### 5/5 — Great!

*2014-11-24*

Great app but wish it had pull down history like the calc app they have.

### 5/5 — True timesaver

*2014-02-22*

Perfect for quick conversions while cooking. Other apps require selecting both units. This one displays all the units that you want (based on how you customize it). No graphics makes it quick. Well done!

### 5/5 — Converter

*2014-01-23*

Very useful, a lot of conversions
