Matson Monitor 4+

I agree with other reviews that there should be an option to confirm pairing of a battery. The app is always picking up random batteries from other users and placing them on my dashboard. This is especially annoying when it triggers a low voltage alarm and it’s not even my battery.
Other than this small issue, the app is quite simple and easy to use

This app has a lot of great potential with a few little adjustments. I have contacted the developer several times and no response.
The app picks up random monitors and has no ability to delete unwanted monitors, this is great for a fleet owner but should have a user definable option for this, this can be addressed by an option to add a new monitor or open monitoring. Next it has no option to select what voltage system your using so when you have multiple monitor devices it adds up the voltage giving you a false indication to your battery pack voltage making it difficult to monitor! This should be addressed with an option if you are running two 12 volt systems ect and should show this separately. Another good idea would be for the export data is to have a downloadable spreadsheet with built in formulas that can graph the data on your computer as displayed in the app verses the way it displays the exported data.
Other than these few issues it is a great app to monitor how your batteries are functioning with your system. Would love to see a few of these changes.

The app works well and is consistent without many glitches at all. There are however two notable glitches. Cranking test: I can tell that the app reads the cranking voltage each time the vehicle is started in the background, although when ‘cranking test’ is selected, it will not show a new result, it only shows the result from my initial cranking test when I installed the monitor. In addition, the ‘charging test’ shows the new result, but reverts back to an old result once I change screens on the app. If these issues are addressed promptly, the app will be flawless.
