Stopped working

Missing In Action

Sensor continually drops out of Bluetooth connection. Frustrating to say the least.

Poor connection

The blue tooth connection is terrible the app is so poorly designed it’s comical and ctek do nothing about it

Batter voltage scale needs improvement

The battery voltage scale is currently zero to twenty five volts.

This makes it very difficult to examine the small changes in voltage which provide the key information on the status of a lead acid battery.
A better scale would be something like eleven to fifteen volts.

Yes, the state of charge graph is very useful, but if there is a voltage graph it should be useful too.
CTEK products are excellent. I’ve owned a few.
Please update this app and bring it up to the CTEK level of excellence.

UPDATE: Years after making this post, still no update or improvement of this app. It could be so much more. I have purchased other CTEK products recently but am VERY DISAPPOINTED in CTEK’s complete lack of interest in evolving this product to at least provide usable voltage information.
