Do you have something that you hate on some web services, apps, etc?
Any kind of problems with the workflow, design, etc.
I like an app that has a button to cancel a service. Many apps hide the cancel button.
This isn't about all web services/apps but if you are making an app that people will use 24x7 (figuratively), I prefer native in that case. An example of this would be Notion, a note-taking app. I tend to keep the note-taking app open at all times so having a webview running for it takes a toll on laptop's battery and performance which I don't like.
