Indonesia has one of the world's fastest-growing mobile applications

markets.Due to the increasing population of Indonesia and with the growing number of

mobile applications in Indonesia, a user-friendly interface is important to stay in the

competition . In this study, we evaluated three big mobile applications for various

purposes. We conducted a separate experiment for each application. The first

experiment evaluated DANA, one of the most-used e-wallet. There were seven subjects

recruited with ages ranging from 35 to 53 years for the first experiment. The second

experiment recruited eight subjects aged 20 to 50 years to evaluate GOJEK, the leading

taxi booking, delivery, and payment application. The third experiment evaluated Blibli,

one of the biggest e-commerce applications. A total of 7 subjects with ages ranging

from 53 to 63 years were recruited in the third experiment. Think aloud protocol and

system usability scale (SUS) questionnaire were used to evaluate the usability of the

applications. From the collected data, the SUS scores were found as 65.71%, 70.63%,

and 76.07% for DANA, GOJEK, and Blibli, respectively. The evaluation results

showed the mobile applications we tested to be acceptable. However, the applications

need to undergo further improvement in order to increase their acceptability.
