Dear sir.
After reading your description and watching your video, I can understand what you need.
Your project is very fantastic project for me and it's really stable for me.
I am a iOS developer with rich experience and high knowledge of iOS app development.
There isn't any tech problem on your project, If you hire me, I will do my best so that I will finish in a week.
In my opinion, if we develop app which is possible to run on iOS and Android, it makes more benefit for your business.
How about my opinion??
Let's talk about your project in more details.
Regards,
