Your blog content was nice, it's great that you set out to create an app to implement what you learnt.

But, I have couple of issues with your app.

1. I tried the web app, the signup required account from other platforms and not a simple email signup.

2. So I downloaded the app on my iPad, Had to subscribe for trying out the app, besides the app looks very bland; some UI elements(settings icon) had conflicts with the label. Was this made with flutter?

In short, the app is not convincing enough to enrol into subscription. Needs better UI/UX to sell the premise of the app.
