## What is CrewAlert?

CrewAlert is the leading mobile app for fatigue risk management for airline safety professionals, crew scheduling departments and airline crew. CrewAlert assists fulfilling vital parts of the ICAO requirements on a FRMS:

- Predictive: Help crew and crew schedulers compare and identify upcoming fatiguing flight duties.
- Proactive. Assists safety departments to efficiently collect fatigue data from your operation – so called fatigue surveys.
- Reactive. Greatly simplifies fatigue reporting for crew but also for safety departments.
- Risk reduction: Built-in context sensitive fatigue mitigation functionality for crew.

CrewAlert contains a lot of functionality, but please note that some parts are unlocked only conditioned a paid-for subscription. Such functionality is marked with an asterisk (*) below.

As part of a joint safety initiative, Boeing and Jeppesen have been developing tools for allowing better management of alertness and fatigue. CrewAlert is the first app designed specifically to help airlines and their crews manage alertness and fatigue. Built on the Boeing Alertness Model (BAM), a mathematical prediction model of alertness, the CrewAlert app puts scientific knowledge in the palm of your hand. 

Please Note: This application is designed for professional pilots and the airlines that they work for. Before you purchase, please read this description in full as well as the Application License Agreement to see if CrewAlert is for you. 

For Everyone: 
- CrewAlert provides the functionality of much more expensive alertness modeling products at a fraction of the cost. 
- While CrewAlert is designed with flight deck and cabin crews in mind, it is applicable to any 24/7 operation where human performance is crucial to safety. 

For Crew: 
- Prediction of future alertness levels from schedule information, prior sleep and personal settings - creating risk awareness
- Allows for creation of what-if scenarios
- Allows for entry of sleep diaries of either actual or planned sleep, which can be used to investigate the effectiveness of potential sleep strategies. 
- Allows for collection of sleep (also via Apple Health*) and alertness data for own use, to learn over time what strategies work best. 
- Built-in fatigue mitigation strategies*
- Efficient fatigue reporting*
- Participate in fatigue data collection
- Alerts and predictions also on Apple Watch*
- Acclimatisation advice
- Estimated body clock time*

For Crew Schedulers: 
- Investigate likely effect on crew members from different scheduling options
- Investigate common causes of recurring problems in schedules, and to consider alternatives
- Simple import of roster data and sharing of scenarios*

For Airline Safety Officers: 
- Efficient modelling of fatigue reports, incidents and accidents in multiple scenarios*
- Analysis mode for investigating fatigue causes*
- Analysis of collected fatigue data via efficient import*
- Import and share data also via iCloud Drive*
- Detailed fatigue reports, received from CrewAlert, can be imported and are pre-modelled using BAM, reducing manual work.*


*) The paid for subscription-version of CrewAlert unlocks the following functionality; integration with Apple Health, use of iCould Drive, scenarios, fatigue mitigation strategies, roster import, analysis view, day/night theme, local light conditions and display of estimated body-clock time.

## Key features

- Predictive fatigue analysis
- Proactive fatigue data collection

### 4/5 — Health data not imported since update 2.2.4

*2025-06-24*

Hi,
Since the last update, health data is not imported anymore, resetting health tab doesn’t fix.

Fixed with 2.2.5

### 1/5 — App is still crashing with a known issue

*2025-01-22, version 2.2.3*

Instead of adding features, like step tracking, existing issues such as the app crashing when requesting mitigation strategies needs to be addressed. The app is useful other than it no longer can provide mitigation strategies, which has been reported multiple times, Jeppesen is aware of but still do nothing to correct.

### 1/5 — Poor Support from developer

*2022-08-08*

After paying full price for the unlocked version of the app a few years ago, I am no longer able to access this version, now being required to pay a monthly / annual subscription. 
I have tried on numerous occasions to a contact support regarding this issue with no response.

### 4/5 — Very Good

*2013-04-07*

Does a nice job of providing strategies for fatigue mitigation.  PDF on Jeppesen site is very helpful.  I like the functionality and interface.  My only complaint is it crashes when I attempt to create an account.

### 1/5 — Bug fix

*2011-12-19, version 1.6.1*

App crashes on opening after bug fix 1.6.1, app just closes down.

### 3/5 — Needs some work

*2011-11-03*

I'm a USAF pilot.  I love the concept of this app.   I think it could go a long way toward improving safety.  After just having input a rather long overseas trip, here are some things I wish we're different:
  - allow me to enter the date/time I begin and end the trip right up front.   This will eliminate the "ends at home station" button that I had to continually turn off for each new leg.  
 - each new leg I enter (after setting the overall begin and end times) should default to a user definable time (i.e. 15 hours after the previous land time).  It sucked having to scroll through the dates each time I entered a new leg. 
 - the default crew brief time within a trip should be user definable.   For example, the only time I'm going to brief 2 hours prior to departure is my first leg out of home station.  From then on, we will have a quick crew brief on the bus going from the hotel to the jet.   It was a pain to adjust this time down for each leg. 
- your instructions don't describe the difference between doing a two leg trip vs. entering two separate flights on the same day.  
- PLEASE add the ability for me to email the scenario to my crew.   The power of this app would come from all of us having the scenario on our personal phones and updating our personal sleep results enroute.  It takes too long to enter the entire trip.  I'd like to assign the task to one crew member who could then share it with the rest of us.  
- ideally, all our sleep journals would funnel to a central server where the AC could look to see how his crew is doing.  In other words, allow me to see updated curves for my entire crew while enroute.   This would provide a powerful ORM tool.  
- overall, it's too complicated.  The user interface is tedious, and I find that I have to constantly refer to the instructions to remember what different parts of the graph represent.  

It's a great first draft and I think the app has tremendous potential for aircrew safety.  Please keep the updates coming.

### 1/5 — Freeze the phone

*2011-10-20*

It freeze the phone when I open the apps

### 3/5 — Crew alert

*2011-09-17, version 1.4.1*

I hope this proves to be a useful tool, but at the moment I find it very complicated to use. The tutorial usually explains how to do things, but doesn't really explain what it means; the sleep journal is overly complicated; the main graph page has alot of data crammed into it for the limited screen size of the iphone.

As a pilot I want to be able to simply input duty times, time zone shifts and sleep/wake times to alert me to fatigue. Crew alert sort of does this, but in a overly technical way. It feels as if it is more a tool for the technicians who designed it, rather than those that use it.

### 4/5 — Excellent App

*2011-09-02, version 1.4.0*

I had a problem with the new version, I did a re-install and unfortunately lost all the data(6months). Otherwise excellent app, highly recommend, will take a few minutes to learn the powerful software.

### 2/5 — Good idea but...

*2011-05-04*

Unfortunately this app is very complicated.  The user interface is not particularly intuitive and the available guidance "tutorial" is limited. I could find no online video tutorial, which would be helpful given the complicated interface. I imagine future updates will be better, knowing that Jeppesen and Boeing are working on this together. However, the current version is a disappointment - especially given the $20 price tag that hopes to use the data you input for their research. Also, it would be nice for the program to allow the user to specify their own company's rest and duty time limits (for those of us non-airliners operating under part 91).  And, an allowance for cabin pressure variations and their effect on fatigue might be a nice addition. (When cabin altitude is 3500' vs 7000' you definitely are less fatigued over the same period of flight time.)
