A Private App is built specifically for your store to add internal features. A Custom Public App is built to be sold on the Shopify App Store to other merchants.
Can you help me if my app was rejected by the Shopify App Store?
Yes! My App Review service is designed specifically to fix rejection issues, ensure Polaris compliance, and help you get listed.
Do you offer Website Audits for themes?
Yes, I can perform a Website Audit on your Shopify theme to identify bugs, speed issues, or broken code.
Which technologies do you use?
I use the standard Shopify stack: React, Node.js, GraphQL, and Shopify Polaris.
