    Is there a reason my percentage is over 10% off? Or any fixes?

    Ask the developer of the broken app.

    But don't know if I'd really trust what he says.

    Do a reboot by holding down the power button and home button for ten seconds. Use your iPad until you completely drain the battery and it shuts off. Recharge it back up to 100%. Before you unplug it, do another reboot. Wait five minutes then unplug it while the iPad is on.

    This may recalibrate the software to the battery.

    And Yourself?
    This is my guess as well. I'd rather trust the Apple battery gauge than the one from the app you are using.

    Don't charge it until it turns off by itself, this will re-calibrate it. If its new it takes a few charge cycles to be accurate.

    The app is reporting percentage based on designed capacity. The battery gauge percentage is based on the current reported max capacity.
