Hello,
I understand you want a MacOS app that accepts a user's name and phone number as input, and plays a random video or image in response. The media is stored at some location on the Mac's hard drive. The media plays on full screen and the user can change it any time by entering their details again. The app also records (datewise) the list of visitors and the number of visitors who viewed each video or image.
If you have a particular design for the form, we can work with that; else I will stick to Mac design principles. I can make the app full-screen by default, and the video/image will play within the same app (no need to open a media player). For the statistics, we can save the numbers and lists into plain text files or whichever format would be most useful to you.
I propose writing the app in Swift since I have previous experience writing iOS apps in that language. I have also worked on other mobile and desktop applications; feel free to browse my profile for specifics.
My bid is for INR 7500 with a deadline of two weeks. You will get to test the app well before this deadline. I am happy with a single milestone to be released once you're satisfied with the work done.
Please do contact me if you want to discuss this further.
Best Regards,
Chamath Ellawala.
