Automatic is the "Smart Driving Assistant" that is supposed to help you be a more efficient driver by monitoring your driving quality and telling you how to improve.  In short, this is the most expensive ODB II code reader you will find that has such a limited set of features.  I understand what they are trying to do (keep it simple), and overall, it does work as advertised.  I was hoping there was more "under the hood" and discovered that it is really quite limited.In the box, you get the white Automatic ODB II code reader dongle.  If you've never seen this connector, it is likely under the dashboard of your car.  There isn't much else in the box other than a nice little "A" sticker you can put on your window to let everyone know you've got the cool new Automatic in your car.  You will also need the iPhone app called "Automatic" and an iPhone 4S or later.  The reason this won't work on an iPhone 4 or earlier is because it uses low-power Bluetooth, a protocol not supported on the earlier iPhones.  Unlike a bluetooth headset, you don't need to pair this with your iPhone.  With the new protocol, it just works.I installed the Automatic app on my iPhone 5S.  First, it was a little disappointing that it requires me to give my name, e-mail address, and create an account/login to their site to use the app.  There goes privacy right there.  Why can't it just tell me how I am driving without requiring me to be registered on their site?When I first plugged Automatic into my car, I got a nice beep from the device itself to let me know it was plugged in.  The Automatic app on my iPhone (now that I was registered) failed to find the device.  I tried to plug and unplug a few times, but eventually I force-closed the app (double click the home button on the iPhone and throw away the app), and re-launched it.  On re-launch, it found my dongle.Once in the app, it is fairly simple.  When you drive your car, it will alert you if you do one of three bad things - hit the brakes hard, drive over 70, or have a hard acceleration.  If that happens, a small sound will play and your "driver score" will get dinged.  When you stop the car, it will record your distance, MPG, and a rough estimate of the cost of that trip based on current gas prices.  It also will maintain a cumulative driver score.  The nice part about the app is that it essentially provides you a log of your drives while it runs in the background of the iPhone, so you can look back on your driving history.There is also an engine status page where you can see the status of the engine and read any codes that may be thrown.  If your car has a check engine light, it can advise you what is wrong.  A problem with the vapor recovery system might require tightening the gas cap.  Yes, this can save you a trip to the mechanic, but I'm not sure how many other codes are that simple.So why only 3 stars?First, I was hoping that the driving statistics would be more meaningful.  How about a graph of my acceleration over the trip, car efficiency, oxygen sensors, etc?  In fact, none of the internal sensors are brought out so I can view them, much less logged over time.  All of this data is aggregated into my driver score.  I can buy a reader for my car that costs less than this and will link with my laptop to provide live car readouts.  I get that this isn't their target market, but they are charging a lot more for this than their competition.  It's "just software", so why not provide an "advanced" screen with live engine status readouts?  Why not log speed data?  It just doesn't do that much.Second, there are plenty of highways where the speed limit is above 70.  Why not let me customize this limit?  This device is not going to be useful in places with higher speed limits.Third, I didn't mention it in my review, but there is a Crash assist feature that I am dubious about.  It says it will get me assistance in case of a crash using an accelerometer in the device.  Why not use the accelerometer in my car, or use airbag deployment as a proxy?  How do I know if it is tuned right?  Will an accidental kick set it off?  And who monitors the crash system?  My home alarm system is monitored by a UL approved monitoring company.  General Motors has OnStar.  I have no idea what sort of back-end system Automatic has monitoring crash alerts and what kind of load it can handle.  Not to mention - they don't know my cell phone number.  If I am in a crash, how will the police contact me?  How will I let them know it's a false alarm?  The app and website are really sparse on this data.So conclusion?  In short, it does work.  If your check engine light is on, it will tell you the code and let you reset it, but a $15 reader will do that.  It will alert you if you make 3 driving errors (accelerate too fast, drive too fast, or brake too suddenly), but even then, the "drive too fast" won't let you customize it for the road.Based on the data they've given me so far, I have little confidence in Crash Alert (it even says "Beta"), and I am sorely disappointed that for $100, I can't view engine status, sensors, or anything else in my car.  At the very least, allow me to log acceleration data on the drive.3 stars - the hardware seems to work, but the software has a long way to go to justify the price.UPDATE:After using this for 2 weeks, going on a long car trip, and driving through a congested city, I am updating this to 2 stars as I am removing it from my car and putting it away until Automatic releases a serious software update.  It is beyond useless.  I drove down I-95 to Richmond where the speed limit is 70.  As soon as I hit the speed limit, it started beeping at me - very distracting while driving.  As I said before, if you can't even drive the speed limit without getting your driver score dinged, what is the point?  I also had a car in front of me stop short.  I slammed my brakes and got beeped at again.  I don't know what the folks at Automatic expect me to do when a sudden obstacle is in front of my car, but I fear the beeping alarm could cause me to get startled and have a real accident.My hopes for this device were that it would be like the Prius in terms of driver feedback.  I don't own one, but I've driven one and noticed the live readout of your MPG.  You learn to slowly apply the accelerator and how exactly to drive to maximize fuel economy.  It is a live readout of everything.  That is what Automatic could have done - live readouts during a drive.  Instead, I get a binary decision on 3 factors.  Two of those factors can be violated for normal reasons that have nothing to do with bad driving habits, and the distracting alarm could cause a real accident.  The only feedback I get during a drive itself is a rotating icon that lets me know a drive is in progress.  Seriously?  No other live display?Meanwhile, by hiding all engine sensor data, there are real things like dirty air filters and low tire pressure that could be reported and could really help fuel economy.  But Automatic ignores this data from the car computer.Seriously, I do not recommend this device.
