Abstract
The most popular social media application for messenger in Indonesia is WhatsApp. One of the new applications made in Indonesia is called Callind. This research will conduct an analysis study related to public opinion on the Callind application. The study analysis process starts from studying the literature, searching for public opinion data regarding WhatsApp and Callind applications, conducting an analytical study of public opinion data regarding the application and then make conclusions. The results showed that the Callind application review value (4.3) was almost the same as WhatsApp (4.4). However, the Callind application needs to be repaired and upgraded again due to several functions that are not running so that the Callind users experienced difficulties and felt uncomfortable using Callind. The features provided are expected to focus on the features associated with messengers.
