To support a tool to care for elderly, this paper proposed a mobile application of nutrition assessment for elderly. The application has been developed in PHP language and it is online support. The proposed app can be freely available, namely day calorie, from the well-known android app space. Experiments have been done on three different models of mobile phone. The process begins with downloading the proposed mobile application from Google Play domain and then completely installing it into those mobile phones. Before getting started to open the installed app, users must make sure the internet connection are working well. Because the proposed app is working as a user interfacing unit accepting input arguments from user and then sending these data through mobile phone media to processing on a certain server and then return an output back to displaying on the mobile phone. Experimental results on performancetest are reported that the average executed time from 20 trials for male elderly case on mobile phones A, B and C are 1.744, 1.686 and 1.639 milliseconds, respectively. For female elderly case on those three models are 2.291, 2.321 and 1.946 milliseconds, respectively. All trials were successful tasks, energy error not exceed 30kcal, each gram error of carbohydrate, protein and oil are no more than 3 grams.
