You should read the book Radical Candour. It will help you provide critical feedback in a respectful and empathic way. Saying “as a fellow dev…” is not a hall pass to light somebody’s work on fire, crap on their tech stack decisions, and claim your opinion is fact.
Strong opinions are good. I appreciate strong opinions. I have many of my own. And i know you’re excited for this app and that it’s become a daily staple for you so you want it to succeed. But React Native is not a bad technology stack. In its nearly 10 years it has evolved and improved dramatically. Huge apps are written in React Native. I bet you use, or have used, some of them and don’t even know.
Technology is a tool. You can write great software and equally bad software in any language or stack. I’ve used a lot of terrible iOS apps, and I’m sure some of them were written in Swift. A language or tech stack is not inherently bad, and claiming such is not constructive feedback, it’s being an asshole.
Don’t be an asshole.
