The result of the tests conducted at different locations and times can be found in Table 1 of Appendices. By comparing the estimated number of people within 100 meters against the number of people found by WeChat (within 100 meters), it can be observed that there is a huge deviation. Similarly, there is a variation between the estimated number of people who is likely to be on WeChat and the number of people found by WeChat.

The differences in the results can be explained by various reasons and they are as follows:
1. Generally, user with WeChat app is found to be very common in China. However, in Singapore where many social apps are available, WeChat can be seen as less popular as compared to apps like Whatsapp, Line and Tango. Hence, smaller amount of users resulted in lesser number of people discovered by WeChat’s Look Around function.

2. People might have installed WeChat but do not access or use it because they are using other apps (i.e. Whatsapp, Line, etc) to communicate. Hence, information such as user’s location is unavailable on WeChat’s web server.

3. For tests conducted outside of institution (i.e. ID 5 – 6 and 8 – 10): it is likely that users have disabled their “location services” feature of the mobile device or have chosen to delete their location data (in WeChat) to prevent unnecessary data lost and to protect their privacy. Such act affected WeChat’s app ability to determine user’s location. Alternatively, user might be connected to a network with weak signal hence WeChat is unable to retrieve data required in a timely and accurate manner.

4. For tests conducted within institution (i.e. ID 1 – 4 and 7): some students do not have a WeChat account and the app installed as they do not own a smartphone or tablet. Furthermore, students might not be on a data plan or are not connected to a network. As a result, it can be observed that the figure between estimations and actual results has a large deviation.
