    So, what am I looking for with this app? Trying to figure out what's wrong with my car that has the triangle/CEL but doesn't show any codes on my ScanGauge or the Piston Android app. I don't think it's the battery, it runs almost OK, just a slight missing/vibration, but I thought I'd check the battery anyway.

    I see a charge over 300V, state of charge at 60%. The variance fluctuates between 0.10 and 0.18, but mostly stays near the low end of that range. The bars on modules 16-19 don't get as high as the others, and each of those will turn white from time to time. Another couple of bars stay real high and are darker green.

    Try the Torque app. I use it with my android phone and a bluetooth obdii reader and it works great

    If you want to use the Dr. Prius app to test battery health, you pay a few bucks and then run a "full diagnostic" test and a battery stress test that gives an estimate of the remaining battery capacity. Results look like this:

    But they were asking about the Dr. Pruis app. I assume that is some sort of low cost knockoff

    No. The Dr. Prius and Dr. Hybrid apps are the same. Those are the results I got on my Prius. Maybe you saw my post before my final edit and it was confusing?

    To be clear, what I uploaded was a screenshot of the report generated when I hit the "share" button on the Dr. Prius results pages.

    Hmm, I didn't pay anything. I just downloaded the app from Google store. I didn't see any other pages/tabs except the live monitor that shows what a wrote above plus three different battery temps, module resistance, something about a "blade" and a delta.

    I used to have Torque, not sure where it went. Maybe that was my last phone. I just want to see what the code is for the CEL, so I can fix it.

    Tap the menu icon in the upper left corner and you will get choices that include the tests that I described:

    Hmm, I'll look again, but I don't recall seeing that menu, or at least, it wasn't there on the home screen. Once I figured out how to get the monitor working maybe it appeared and I didn't notice. Or, maybe it's because this was a free version?

    I think I had to pay to do any of the tests. I did, it was something like $10~12 (CDN) IIRC.

    So far I haven't done either of the "dynamic" tests @royrose posted above, I should. I'm chicken to do the accel/decel test on a public road, and I guess better have my wife "manning" the cellphone. The other one, where you sit idling, load up the engine by running AC and all, seems daunting as well.

    I've done the static/basic test a few times, not that sure of the results. No warnings, red colours, so maybe good.

    The app doesn't have full functionality with Gen 1s - ron, you usually seem to be posting about Gen 1s? That's why it's free for Gen 1, and why it won't do any of the automatic tests.

    I can't tell you any "fancy" ways to use it because I haven't fussed with it enough. After I replaced my HV battery I just drove around with it for a while looking for anomalies - like a lot of stuff in red. (It puts graphics and numbers in red is they're in the "error zone"). Now it sits on my phone in case I have a problem.

    But there are ways to use it to test out specifics of the battery. I just don't know them, but I've seen them on the site. (E.g. I have some vague recollection of something like finding a traffic-safe incline and driving up it in reverse while recording block voltages (discharging the HV battery) and then roll back down (putting charge back in) so that you get some read on discharge and recharge by block. I'm sure what I'm saying is off base - I was just going to search again if/when I had a need).

    OK, so really not a lot of info for Gen1s. I already get SOC and Voltage from my ScanGauge.
