Pros and cons of LeafSpy Pro app for iPhone and iPad

LeafSpy Pro app good for

Works flawlessly with LELink Bluetooth Low Energy. Connects automatically, tested on iPhone 4s.
This app gives more info for the Leaf than the OBD2 interface at most Nissan dealerships over here in Japan! Love it!
2013年10月納車のリーフにバッテリー状態など知りたかったので、思い切って購入しました。 ELM327 OBD2wi-fi でiPhoneと繋いでます。
This is a great accessory for the leaf. A few functions in particular: - better estimate of range (given your personal miles/kwhr) - state of battery health (good when purchasing car) - charging status graphs, particularly useful during a quick charge - ability to view and reset trouble codes - a few options can be set (door locking) a few changes would be nice however: - the "developer website" redirects to a forum thread - help is spotty and incomplete - the user interface is a complicated jumble As an example, how would a new user determine if his battery is healthy or not? Although its there, not one page says the word "health". However, none of these organizational shortcomings will make me me dock it a star - its just too useful!

Some bad moments

Ive been waiting for a while for this to come out. Makes monitoring capacity degradation easy and is required whenever you are going to be cutting the range close.
A real asset for the community. Tons of data to geek out on your Leaf. You can also change modes to unlock doors upon pressing Park rather than on power off.
Noticed right away that one tire over-inflated. Would not think to check that coming off lot. App packed with useful info, helping to ease learning curve transitioning to ZEV. Anticipating more great functionality in updates to come.
I bought this but immediately found it did not work so I bought Leaf Stat...worked great!
If you have a Nissan Leaf, this is an excellent app to find out details about your battery usage and other aspects of your car. Some of the information can be overwhelming if you are not the technically minded. However having it has taught me a lot about my car and how it works. I originally had the first version 1.0.1 and the newest upgrade to 1.1.0 only made the app better. I easily connected to my OBDII ELM connector without a problem. Additionally, the creator is on MyNissanLeaf.com to help with any difficulties you may encounter. Thank you very much!
This app provides more details about your battery than any other Leaf apps out there and data can be exported. GPS logging and all and best of all the app maker is active on mynissanleaf forums so is actively making the app even better. Helped me find the right car and get my battery swapped on warranty. Big thanks! Very easy to use the only thing required is a wifi obd connector which can be found on amazon.
