Bubble.io for building a mobile app

Hello! I hope you're doing well. I'm considering using bubble.io to create a mobile app and I have some questions I'd like to ask.

Firstly, I'm curious about the cost involved in converting a web app into a mobile app for the App Store and Google Play Store. I'd like to understand the financial investment required.

Secondly, I'd like to know the level of effort needed to make this conversion. It would be great to get an idea of the time and resources that I'll need to allocate.

Additionally, I'm interested in any limitations or disadvantages of using bubble.io for this purpose. If there are any potential challenges that I might face, I would appreciate knowing about them.

Lastly, I have a relatively simple app idea that aims to connect different industries and efficiently organize their data into an agenda. If you have any insights or advice based on your experience, I would be grateful to hear them.

I'm looking forward to hearing from you and sincerely appreciate your help. Thank you
