Could you please provide a bit more detail about the issue? What exactly isn't working on your end? Also, we're a bit confused by your comment about payment: This app is completely free and supported only by ads. What did you pay? Additionally, how did you contact us? We haven't received any messages at our support email physicsapp@outlook.de.
