GivEnergy Monitor for Android

I bought this tablet https://www.amazon.co.uk/dp/B0F5389J9J?ref=ppx_yo2ov_dt_b_fed_asin_title
It was a random find by Rubikcube on Amazon but since I know nothing of android devices was wasn’t able to chose from the huge selection from broken upwards available for sale there.
Looking good so far ...
