Does anybody here have experience launching Shopify apps?

Homies/friends/fellow company builders, We are launching a Shopify app in the coming weeks, and besides that we are looking for companies willing to test, we would love to see if there is anybody out here that has experience in launching them, and if so what the experience has been? The app that we are launching in short is: - A button at the end of the order checkout - That button will turn the transaction between the business and the customer into a product - This product will be stored in our Fryda wallet (available on iOS & Android), and will contain all important purchase information like receipt, warranty, price, etc) - What this does for the business is that it helps business get more out of sold products. The product is a permanent connection for the business to the product, even when it would switch owner. - Giving the business more upsell and cross-sell opportunities and access to GDPR friendly data about their customer base
