I've got this one on my 1st gen nexus:
https://play.google.com/store/apps/details?id=com.ds.avare&hl=en
I've only done a few xc flights with it, but it seems to work fine.

Hi Rick,
It was not my intention to offend you, or hijack your thread. It was
simply to ask if you'd considered one possible downside to your battery
change. Sometimes changes can have unintended consequences. I've had it
happen to me, and I suspect that it's happened to almost everyone,
especially those who dabble in experimental aviation.
Please accept my apologies, and I'll try to refrain from offending you
in the future.
Charlie
