Hi there,
I hope you are doing good!
I've spoken to one my developer and we can help you to achieve the desired output as stated in the requirement. Before that needs to know technical details as follow.
1. You want us to develop in demo or wants to make changes in current application?
2. Which technology being used if the application is already you have Swift or Objective-C?
We've been in this sector for over three years and have a lot of happy clients. We have more than 6 years of experience in developing Android and iOS apps. Our development staff is well-versed in Objective-C, Swift (all versions), Android Studio, Java, and other programming languages.
I'm hoping for a favorable answer.
