### 2/5 — Erratic reading

*2024-11-26, version 1.4.0*

Was good when new 6 months ago but now reads “low power” and 32% when my batteries are fully charged. Same symptoms on two different batteries. Needs an update that is not available. Worrisome when in my kayak.

### 1/5 — WHERE IS THE UPDATE!!!

*2024-10-19, version 1.4.0*

Can you open the app quickly shows you the battery level and then closes right away, there’s no other functionality to it anymore. When I first installed it, I could do things like a Frank test on it now because it just opens and shut right away not functional.

### 1/5 — Can’t monitor two batteries on same phone

*2023-09-15, version 1.4.0*

Have two batteries to monitor (vehicle & trailer). Each battery has a monitor (different brands) but they both use same app (not good), so they conflict.  Can only monitor one battery.   Also, this app has issues. Shuts off without warning and when in setup. Did it many times.  I would not use again

### 3/5 — Battery app

*2023-08-17*

Worked perfectly fine when I first got it now the low rpm charging function has stopped working saying my engine isn’t running when I can probably assure it’s deffo running and the app all together has stopped been in touch and they want me to send it back and then wait to see if it’s faulty and then if it is send me a new one which I personally find ridiculous as I won’t be able to know what’s going on with the battery, I’ve just spent £900 on a battery yet they think I’m going to rob them of a £40 piece of kit for the app plus it needs more updates to fix said problems this is a good bit of kit when it works and is constantly working

### 2/5 — Needs an update

*2023-08-05, version 1.4.0*

Alerts don’t work and switching between cars takes twice as many clicks as it should. It should tell the user when it is advisable to connect a charger. The Bluetooth monitors are great but this app lets the consumer down. Come on Antigravity, stop leaving this on the back burner.

### 1/5 — Alerts non-functional

*2023-05-26, version 1.4.0*

First off, love the Antigravity batteries. Saved me about 35 pounds in my track car. The app however has stopped being useful as it no longer seems to revive alerts/status notifications from the battery (used to get daily alerts without prompting)
Don’t know if this was an update issue or not but has become of markedly less useful. Can manually ping the battery but was more useful before

### 1/5 — Does not work properly

*2021-05-11, version 1.4.0*

Indicated voltages are not accurate. App send low battery level wrong warnings now and then, but fails to send predetermined % low battery level warnings at all, making this gadget useless to warn about a dead battery.

### 2/5 — Major phone battery drain

*2020-10-10, version 1.4.0*

Works fairly well feature wise but drains the phone battery like crazy.

### 2/5 — Only works on regular battery

*2020-07-10, version 1.3.1*

I bought two trackers: one for regular battery and one for lithium. Lithium one doesn’t work. Keeps saying needs firmware upgrade but it’s an empty upgrade. Doesn’t do charge test. The tracker is useless without the app

### 5/5 — Better than expected!

*2020-03-18, version 1.3*

I was very surprised at the build quality and the graphical interface quality. The wire connectors are robust and sturdy, which is uncommon nowadays. 

I opened the pkg and took a picture of the unit to send to a friend. To my surprise when I took the picture there is a “QR Code” on the device and my camera automatically used that and opened the App Store! I pressed “YES” on 2 or 3 set up questions and the Bluetooth auto connected and was operating perfectly in than a blink of the eye. 

I have used a lot of Bluetooth devices before and none of them ever started up and synchronized this easily before. Kudos to the engineers for using the latest and greatest BT protocols! 

I’m very happy with this and I would highly recommend it to anyone that wants to keep an eye on battery voltage on your daily driver or especially the weekend cruiser.
