I appreciate you for performing the steps in making a price rule, @Phish phaktory. Let me provide additional information regarding this matter.

Creating a price rule is exclusive to users using the web. That being said, it isn't available to any of the QuickBooks mobile applications. 

For now, we can use QuickBooks Online in the mobile browser to access the price rules you've created.

Additionally, you might want to run reports to see your sales and inventory status in QuickBooks Online. 

Keep me posted if you require further assistance in managing inventory. I'm always here to help. Have a great day ahead.
