Hi
I read the project description and I'm interested in your project.
I have a suggestion for you if you want to speed up your project progress, the budget matters, and you need the application for both android and ios platforms, using the flutter framework will be a wise decision.
write once and build output for android and ios.
i will be glad to help you with the project, hope to contact me and send me more details
if you have any questions don't doubt to ask
hope to have a nice cooperation
ps : the applications will be supported for six months
thanks
