Track Battery Status from Your Phone

Free App with tons of features! Our app makes it easy to monitor your battery’s voltage, automatically check its performance during starting, and test your alternator’s charging operation. Quickly view real-time data as well as historical results (72 days) in the App. Graphically displays the dates, voltages and more. Download monthly data to a spreadsheet file for easy review or to keep a longer history. The tracker can 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.

App requires smartphones with Android 4.3 and higher, or iPhone 4S and higher.

Voltage Test

The Voltage Test features let you monitor your battery’s real-time voltage as well as fluctuations and will track this data over 72 days for your review. This is Automatic, not manually run. The real-time data is shown on the App’s main page, and you can go to the History page to see data for the past 72 days.

• Real-time Voltage reading.
• Real-time Voltage Graph over 5 minutes span.
• Real-time Charge percentage.
• General Charge status (“ok”, “charging”, “low charge”).
• Voltage History Graph with 72 days of data.

Cranking Test

The Cranking Test automatically logs data for each start of your vehicle. It allows you to see if your battery is getting weaker and not staying in a high enough voltage range when the engine is started, which may indicate an aging battery or a low state of charge.

• Automatically logs Cranking date and time on each Start attempt of vehicle.
• Actual Cranking Voltage reading.
• General Cranking Voltage reading (“ok”, “low voltage”) with colored indicators.
• Cranking Voltage Graph over the number of seconds the Start took place.
• Data stored for 1 day on the Cranking Test page but can be reviewed in Voltage History Graph that stores data for 72 days.

Charging Test

The Charge Test allows you to see if your Alternator is charging the battery and working correctly.

• The test has three steps with basic instructions for you to follow.
• Step 1 is an Idle Speed test.
• Step 2 is a High Speed test.
• Step 3 is a Diode Ripple test.
