Its not identical to the percentage of my laptop

Its easy to download and its a good app. But I don’t know if its really meaningful. When I first loaded my laptop (new, not used before) the app showed me 2 cycles. A bit strange. And now my laptop shows me a current charge of 100% and this app of 95,7%. So I’m a bit cautious.
