Simple Power Apps Inventory App

I need to create a simple inventory app in PowerApps.

Please check attachment to see specifications

I don't know how it is working in PowerApps but in a normal App we can use 2 tables :
- one for items and one for events.

I don't need user authentication or role management in this app.

Ideal Skills:
- Proficiency in PowerApps
