### 5/5 — Instant access to needed ICS structures

*2017-08-17, version 1.2.1*

Good app to have with easy to use selections.   Highly recommend

### 1/5 — Buggy and not user friendly

*2016-03-22, version 1.0.1*

Not impressed at all with the app, the search function is somewhat of a pain, for example if I search "high rise" it shows no results, you must type "high-rise" and have the exact verbiage to produce results. That is the last thing you want on an emergency scene. The app also crashes intermittently when being used.

### 2/5 — Eh...

*2015-07-24, version 1.0.1*

So far it's been very buggy and hard to find information. When I've done searches for specific things, either it's a long list or empty. Sometimes when I click on a search, it goes to main page. Even the main page has vague terms and hard to navigate (not laid out like paperback). Very hard to use and not worth the $$ however gave 2 stars because technically the information is there.
