Build a simple android/ios app

Hi there,

I'm looking for expressions of interest to build an android/ios app.

I think something like flutter or react native would be best but I'm interested to hear your opinion.

The app would need the following pages:
- welcome page with a single button
- 2nd page for adding location and a list of 'activities'
- clicking on an activity opens a group message with everyone that it a part of that activity
- profiles
- messages page with your group/activity messages as well as one-on-one messages
- page to create activities

I can share mock ups and more details upon request.

Let me know what technology you would use and what your quote is!

Cheers
