I design Gear watch faces for Samsungs Gear wearables. I need 2 In app purchase SDKs
The first: Where the face is free for a certain amount of time maybe 1 hour before prompting the wearer to pay for it or it will be no longer available.
Second: The cover is free and they can tip on a voluntary basis.
Design size 360x360 ( should auto adjust for slightly bigger or smaller watches.)
Will attach the In app purchase guide for your reference. Also including a sample of what it might look like I am not locked down to this look exactly but something similar to this would be great.
Kindly refer the below link for my android wear watch application development work.
