Nutrilabelapps© is an interactive augmented reality mobile application (app) providing nutrition menu labelling specifically built for Mutiara Café, a café in Universiti Malaysia Terengganu. However, no evaluation of the usage of Nutrilabelapps© has been carried out. Therefore, this cross-sectional study was aimed to determine the knowledge and attitude of nutrition menu labelling among Mutiara Café customers; the feasibility and acceptability of the app among customers; and also, the relationships between knowledge, attitude, feasibility and acceptability of this augmented reality nutrition menu labelling app. This study was conducted among 108 Mutiara Café customers who owned a smartphone and were able to download the Nutrilabelapps©. The data were analyzed using SPSS version 25. Findings showed that only 4.6% of Mutiara Café customers had good knowledge of nutrition menu labelling, while 71.3% of them had a positive attitude towards nutrition menu labelling. Nutrilabelapps© was accepted by users based on the feasibility (67.6%) and acceptability (75.9%) of the app. Remarkably, there was a significant association between knowledge, attitude, feasibility, and acceptability of the app at p < 0.05. As a conclusion, Nutrilabelapps© is highly recommended among the café customer despite their low knowledge of the nutrition menu labelling. Therefore, more education of the public about nutrition menu labelling is highly recommended
