Hi medmark2021,
Thanks for posting the project. I have gone through the GLYMPSE app. The estimate is just ball-park and would be revised once we receive the requirements document. In the mean time, could you please help us to solve the following queries:
1. Well, they have a dedicated website to handle things without which few features cannot be added to the app. So do you want us to build the website as well at additional cost or just the app with specific features.
2. Will you provide the UI assets like images, logos, sound files or do we have to create the design ourselves
3. In order to add push notification service we need to add some code to the server as well.
4. Have you got Apple's iOS developer account to submit the app to app store.
Have few other queries but would like to discuss them later.
I have developed an app where a user can chat with other users if within range.
Please read the private message board for my iOS application development experience and some notes.
