Hi Dear, Hope you are doing well !! I am Aman, i have expertise in mobile app development for more than 8+ years.
I really liked the idea of your application. I would suggest you to go with React native (cross platform) as this will cover both ios and Android users. In order to get your dream a reality the front end and backend technology has to be chosen wisely and also keeping in mind the future add-ons in the app.
We can discuss this in details on chat or skype: er.amandeep740.
Thanks,
Aman
