Real time timer/stopwatch in mobile app

Hi,

I want to do a proof of concept for real time timer across mobile applications, I have done some analysis and I am looking for mobile application (1 or 2 screens) depending on one of below services to ensure the least latency between timers, it will be better if you have any existing app that was built for one of them (Let me know if you have existing app)

The use case is below

We have an admin user that starts a stop watch counter from one screen from mobile app

Other users (let’s say they are 6) need to see this stopwatch counting up seconds on their screens from their mobile app till each one of them stops his counter. When a user stops his counter then Admin user will see that this user counter was stopped and record the below parameters for this User

Start Time: The time counter was started by Admin side

End Time: The time counter was stopped from User side

Difference in microseconds between the 2 times

Time stamp when the Client received the start counter event

Time stamp when the Admin sent the start counter event

Time stamp when the Admin received the end counter event

Time stamp when the Client sent the end counter event

Payment rules

50% escrow on project selection, Release after first demo that I test

50% escrow after testing demo, Release after all bugs are fixed

Skills: Amazon Web Services, Android, iPhone, Mobile App Development, node.js
