Tutor/Mentor for occasional team viewer sessions

Looking for experienced mobile developer to help out remotely, in occasional short screen sharing sessions.
Change and explain things in Blueprints whenever I get stuck.

Current example: I am stuck on calibrating Gravity Input on mobile device.
I can control a ball by rotating the mobile device and I can store the Gravity vector when I hit a Calibrate button. But I cant figure out how get a value out of that, that can be used for x/y input

Project: Just for educational purpose
Payment would be for each 15 minutes of our session and directly afterwards in case you solved the problem.
Suggest a price and your remote desktop tool of choice. Availability on weekends and German working hours is a plus.
