JB4 Mobile App Reviews

Major flaw

Needs security. There is nothing to stop someone else from connecting to your car and changing crucial settings causing damage.

Awesome in every way

A++

Great app

Wish it was included in the cost of the JB4Connect Kit, but anyway, its a great app. Can do all the stuff the burger software on the PC can do plus more. Occasionally the readings glitch, but Im sure Donnie will figure out why and fix it.

Gauges

Hope next version has other gauge style options and colors %100

Must have app for JB4 users

I really like this app and it works really well for the JB4 Connect Kit. The app should be included in the JB4 Connect Kit, but whatever. My issue with the price doesnt take away from how well this app works and how much easier it has made data logging and monitoring the JB4 for my M4.

Outstanding support app for JB4

Dont know how I operated and tuned my car before this. Outstanding realtime display of what you car is doing and make tuning a breeze. Thanks for the outstanding product and keep up the good work.

Great app. Recommend for jb4 owners BUT.....

I belive this app needs to allow you to choose how many gauges you can display. That would be perfect!! Other than that the app is great works perfectly and would recommend it to every jb4 owner.

Great app

Makes logging and using the JB4 much easier. I have the Rev2 kit on my car and could not be happier!

Does what it says.

If you run JB4 this is a no brainer.

Awesome data logging

Love the real time data logging through your phone via Bluetooth. Makes things a lot easier to monitor. I always have it on whether I’m driving to work, going to the gym, test driving the car etc. Much more convenient than a laptop!

Doesn’t connect

The app does not connect to the jb4, it keep asking to select the type of engine

JB4 apps

I good like to return the JB4 apps

It’s very expensive app / no partial refund for one month use.

Make sure you are dead set on keeping your JB4 kit since this app is none refundable once you buy it. You won’t be able to transfer it to another user like your friend also. So If you decided to sell your new JB4 tuner kit, count this app cost as your extra loss.

Great app and a must have with the JB4

App is freakn awesome! So much easier to work with a phone than a laptop. Please change the background color as it’s too dark to read and if gauge selections can be adjustable from 1 to 6 gauges this would make it even friendlier to use.

Essential app

Great app for the BCS JB4 users, but please drop the blue font with black background... its nearly impossible to see

Not working properly screen upside down and backwards can't read anything

I just bought this app I can't read anything it's all backwards upside down can I get some help please?

Incredible Support

First of all, having Bluetooth connectivity for the JB4 has been a valuable enhancement. When I had a problem with the BT hardware, I sent the unit to Donnie and after a few email exchanges, he fixed the problem and sent me a replacement unit. The app quality is outstanding and support all the more so. It is amazing that there is such an outstanding product for a niche application. Just get it! If you already made the plunge to get a JB4, the Bluetooth interface will greatly enhance your investment.

Username/password server fails

The app was GREAT until the username/password was implemented. Now I can't use my iPhone turned iPod for sole purpose of using it to connect to JB4 unit. Remove the username/password and this app will gain back its 5 star rating.

Country Check for Passive Delete?

No thanks.

Awesome

It's money well spent!

Great tool

Love using the app. Updates I hope to see. A gauge for fuel economy (miles per gallon). Add more of the steering wheel controls in the app for easier control. Also a eco map to maximize fuel economy, similar to eco and sport on modern BMWs.

App needs updating

This app needs an overhaul from top to bottom. The UI is very unfriendly. For the price of the app, it'd be nice fnthe developers atleast made the app look good

AMAZING

Best option out there. Everyone loves it, except all the v8 guys (mustang)i blow pass! This defines, on the fly tuning

Fraud

This app is a joke. Charged me over $30. Already called my credit card company and for a non payment and fraud by the app creator. Don't buy it!!!!

Major flaw

Plug and play out of the box

As with everything BMS makes, this is amazing. Works perfectly after a five minute install. Updated firmware on first login. This would have cost thousands a few years ago! Love you guys!

Good app, some flaws

Good app for data logging. No longer need computer jb4 app after. Yet there are some bugs and the 0-60 and 1/4 mile are no longer a feature. If they fix those then I would give it 5 stars.
