### 1/5 — Free version exists

*2026-05-14, version 1.171*

Downloaded this because it came up first in my search but you have to pay them to unlock all pages. There is an official FREE ERG available by USDOT

### 1/5 — CAUTION!!  Not the FREE app by D.O.T.

*2026-05-13, version 1.171*

I downloaded this because I thought it was the free ERG DOT app.  IT IS NOT!!  This is a PAY app, and quite ridiculous at that.  Why pay $30 annually for information that is already free?  If you want to pay for free stuff fine, but if you want the free ERG look for that app instead.

### 5/5 — Great for hazmat lessons

*2024-09-13*

I work as a teacher teaching year 9 students through a Google meet after school about hazmat training. This is a great app and has really helped them to achieve high grades on there exams and further learning opportunities

### 1/5 — Robb189

*2024-09-10*

Paid for the premium. 
It’s not up to date.

### 4/5 — Update

*2024-05-06, version 1.153*

This a a very useful tool while being on the job. However the 2024 version in print has been released . Why has the update for 2024 not been released for the app yet ?

### 1/5 — This isn’t the official app they want to charge to view this there a scam

*2024-04-22, version 1.153*

PLEASE DONT DOWNLOAD!!! Use free app by the US department of transportation and pipeline administration 

The free official app is “ERG 2024” or “ERG FOR IOS”  IS A FREE APP BY THE US DEPARTMENT OF TRANSPORTATION. They have rail cars trailers and placards

 This app wants to charge a $10 one time fee to unlock guides

### 1/5 — App outdated.

*2023-09-05, version 1.153*

This app is outdated. Please download ERG for iOS by the national institute for pipeline safety for updated information.

### 1/5 — Offer’s In-App Purchases

*2022-09-29, version 1.146*

Whose stupid idea was that? It’s bad enough to be asked to review an app, but having to say, “hold on, we’ll see how far to evacuate you as soon as I can get through these ads.” 

Not to mention any banners or ads may cause confusion with the instructions needing to be provided.

This APP needs to be 100% ad free at all times. Without purchase to upgrade to that.

### 2/5 — Review

*2022-09-24, version 1.146*

Very difficult to use compared to the old one.

### 1/5 — Upgrade charge without warning

*2022-09-21, version 1.146*

Do not upgrade if you do not want to spend $13.99. Unable to refund! Did not have a warning.. also poor navigation, cannot access table 1,2,3 etc
