## Most critical reviews (7 lowest-rated)

### 2/5 — Doesn't seen to work well with iOS 4

*2010-07-09*

For some reason, the App does not work well on my Ipod Touch.  I think it might be related to other problems I have experienced since I've downloaded the iOS 4 update on my iPod.  When I get to select the Zone List, the App immediately closes down.

### 5/5 — Great update

*2021-10-03*

Love the update to 2019. About time.

### 5/5 — Engineer

*2010-09-10*

As a 62.1 user, I have found this application to be well worth the money. I like the way it works and looks. The ability to e-mail the results to my office is very convenient. Great work; keep it up!

### 5/5 — Simple to use

*2010-08-05*

I like how simple this app is to use. Nice clean interface, and it allows me to store all my projects without losing data. The best part is the email functionality so I can email the results back to my office laptop. It's been useful for LEED calcs, too.

### 5/5 — Very useful

*2010-07-12*

This is an incredibly useful app for quickly calculating minimum ventilation rates for all types of spaces and buildings. I like how it mimics the spreadsheet that comes with the 62.1 standard, yet it is also much improved in the sense that I can easily use it out in the field. Also, it allows me to store multiple projects, systems, and zones all within the app and come back later to update and view the information. Great work!

### 5/5 — Good to use out in the field and also for LEED

*2010-07-09*

I've been using this app for a couple weeks now, and I really find it useful in the field to do quick vent. calcs. The best part though is emailing back to the office so I can use it for my LEED calculations. Nice little app.

### 5/5 — Good to see 62.1 for the iPhone

*2010-06-22*

I'm a moderate user of the spreadsheet that accompanies the 62.1 Standard, and this app is a great complementary tool for doing quick ventilation rate calcs out in the field. I really like the fact that I can email the inputs and results as a spreadsheet so I can work with it on my office laptop later on.

Awesome app, ASHRAE!
