Never come back to a dead battery!! C8 Tech
We are proud to launch one of the first Bluetooth Battery Tracker for Lead and Lithium-Ion Batteries!
Forget about voltmeters or even popping the hood to see how your battery is doing!
The Antigravity Battery Tracker monitors your vehicle battery status through your phone or tablet by using our free Battery Tracker App (iOS or Android, Bluetooth 4.0). The app has three main pages: Voltage Test, Cranking Test, and Charging Test. The simple interface makes it easy to monitor the battery's voltage, automatically check its performance during starting, and test your alternator's charging operation. You can view real-time data as well as historical results (31 days) that graphically display the dates, voltages, and more.

The tracker will even send a warning to your phone if your battery is getting low and needs a charge. You can choose the alerts and notifications you want to receive.
Histiorical graph looks like this.. in this particular dispaly is shows on Feb 22nd at 2:30pm the car went on a drive...appears they stopped for about 30 mins then started and went driving again.. then stopped again at about 4pm and the car wasn't driven any more... then if you followed the next week you could see its daily parasitic drain if they did not drive again.
This is the Real-Time voltage indicator for the previous 5 minutes... in this example it we started an charging at about 14.5v then we shut down and shows it going back down to resting voltage.
So you have 5 mintues display of the last 5 past minutes as real time graph.... then you can also look at the historical data as the graph above shows for a full day. So if you have the unit you can review past days and see how fast the draw is on the battery. You can see if you have a fast or slow parasitic drain and how long it takes for the drain to take it down to a low state of charge.
Real time over past 5 minutes....

This worked for a little over thirty days and then stopped communicating with the app. It will connect via Bluetooth and can see the device but can’t read any data or voltage, nor can it pull the firmware version.

1- Thanks for your post, I was unaware of it and I went to the link and found it...... This allowed me to also learn that someone has appropriated our name and is calling their name Anti-gravity... but its not us.... so it must be some dealer who buys from us or a distributor. Anyway thanks because we did not know about this, and want to track this seller down and say to stop using our name.... also we want to try to reach out to this reviewer and tell him to correct his review... because it NOT correct. I would gladly admit if we had products fail.
2- Now about that review.... This reviewer neglected to come back and correct his review.... I say because this problem was NOT due to our product or App, but rather that Apple changed their Operating system with the latest iPhone 11 when they released it in September, and we had no prior notification of this from Apple. So anyone who upgraded to the iPhone 11 or changed the operating system on their earlier iPhones to the newer one had the Battery Tracker App stop working. The fact is we didn't even know Apple was changing the Operating system and that there would be an effect until we got a bunch of phone calls about the App not working..... So our Developers had to update the App to work with the new Operating system. That took us a week and the new App was ready and it all worked again. It had NOTHING to do anything defective or breaking in the product... it was a change in Bluetooth communication Apple made, then we had to change to a certain protocol. And the last thing is the App notified everyone to update it.....yet this person never came back and corrected their review. So its a bit frustrating. The same thing happened on our App rating in the App stores... half the people never called us to ask what happened, they just said the App failed and posted a low review, which is frustrating. But that is how it is nowadays.
To anybody at all, if this product is not liked of doesn't work as we describe I will give you a full refund and pay shipping back to us. The product utterly and completely kicks butt...
