Keenoa™ is a novel Canadian diet application (app) currently used by Canadian dietitians to collect diet-related data from clients. The goal of this study was to evaluate Keenoa™ based on user feedback and compare it to a conventional pen and paper method. One hundred and two participants were recruited and randomly assigned to record their diets using this application for 3 nonconsecutive days. Following this, participants were invited to complete an online "exit" survey. Seventy-two subjects responded, with 50 completing an open-ended question asking for general feedback about the app. Data were reviewed and 3 main themes emerged: strengths, challenges, and future recommendations. Strengths associated with the app consisted of picture recognition software, the additional commentary feature, and the overall pleasant data collection process. Challenges that were identified included inconsistencies with the barcode scanning features, the limited food database, time to enter food details, and software issues. Future recommendations included using a larger food database, pairing dietary intake with physical activity monitoring, and having accessible nutritional data. Despite these limitations, participants preferred using mobile apps to record diet compared with traditional written food diaries.
Keenoa™ 是一款新颖的加拿大饮食应用程序（app），目前被加拿大营养师用于从客户处收集与饮食相关的数据。本研究的目的是根据用户反馈对 Keenoa™ 进行评估，并将其与传统的纸笔方法进行比较。招募了 102 名参与者，并随机分配他们使用该应用程序记录 3 天的饮食情况。之后，邀请参与者完成在线“退出”调查。72 名受试者做出了回应，其中 50 名完成了一个开放式问题，要求对该应用程序提供一般性反馈。对数据进行了审查，出现了 3 个主要主题：优点、挑战和未来建议。该应用程序的优点包括图片识别软件、额外的评论功能和愉快的整体数据收集过程。发现的挑战包括条码扫描功能的不一致性、有限的食物数据库、输入食物详细信息的时间以及软件问题。未来的建议包括使用更大的食物数据库、将饮食摄入与身体活动监测配对，以及提供可访问的营养数据。尽管存在这些限制，与传统的书面食物日记相比，参与者更喜欢使用移动应用程序记录饮食。
