Sprint reflection

This sprint we are doing the mobile phone. This is really hard for us to do this. In this sprint we try a lot of different way to do push in the mobile. At the beginning, we did not think a best way to do that. After that we did waste a little bit time. Then, we figure out how to push in the mobile phone that is use the browser in mobile phone but here is one big problem we can not fix that is browser update. The browser company wants to protect user privacy it now allow some unauthorized web to send the
push to user. We need to think about this and find the best solution in our final presentation.

Sprint Retrospection:

In this sprint, we are almost finish everything for the whole project. After we linked all functions together, we fixed some small bugs of the push function, and make sure it will work on the mobile phone which has a web browser.

Good	Could have been better	How to improve?
Every function works well in the project	There is an update in google chrome, so this may make our push have some problems.	We cannot do anything fot the update, but if you have the previous version browser it should work well.\|
