App on Androids shows different temperature than reported for PWS

[Rolandoz]

I am reporting every 5 minutes from my PWS. Right now temp. is -0.7 C and dewpoint -1.8. On web interface (see URL below) it's reported as -1 C but in app for Android it says -2.0 C. I wonder why? Could it be that app reports dewpoint instead? Hmm.
