One of the best chess apps out there sadly the rewarding/substracting points engine seem to be broken on my phone whever I lose, a ridiculous amount of points are substracted up to -240 points and a win will only give max 40 points, to make the matter more laughable if I draw I nether win nor lose points but my adversary will win points; when I started to notice a screenshot was taken. Funnily enough when my sister had me playing some games on her phone wins=+5 up to +10 Loses=-5 up to -12 Bias?
