With the increasing use of smartphones in people’s daily lives, mobile accessibility has become a key factor for them. Tourism is one of the sectors that has benefited the most from this growth but has not yet reached its full potential as accessibility has not yet been fully exploited. The main goal of this study is to assess accessibility in mobile applications for the tourism sector. Thus, 14 mobile applications were analyzed, using a manual and automatic methodology through the proposal of an evaluation model divided by quantitative and qualitative requirements, as well as the use of features such as VoiceOver and TalkBack. The results show a high overall number of errors in most quantitative requirements as well as non-compliance with most qualitative requirements. On iPhone 4, “Viseu – Guia da Cidade” was the application with the highest rating, while on Wiko GOA, it was the “JiTT.Travel Funchal” application. In turn, on iPhone 6 Plus, iPhone XR, Nokia 5.1 and OnePlus 6 devices, the best results were achieved by the “Viseu – Guia da Cidade,” “JiTT.Travel Funchal” and “TUR4all” applications. Regarding the accessibility of mobile applications on different versions of the same mobile operating system, it was concluded that there are no differences in their accessibility on both operating systems (iOS and Android). Finally, regarding the accessibility of applications on smartphones with different screen sizes, there are also no differences in their accessibility.

随着人们日常生活中智能手机的日益普及，移动可访问性已成为他们的关键因素。旅游业是从这一增长中受益最大的行业之一，但由于尚未充分利用可及性，因此尚未发挥其全部潜力。这项研究的主要目的是评估旅游部门在移动应用程序中的可访问性。因此，通过评估模型的建议（使用定量和定性的要求以及使用VoiceOver和TalkBack等功能），使用手动和自动方法对14个移动应用程序进行了分析。结果表明，在大多数定量要求中以及在不符合大多数定性要求的情况下，错误总数很高。在iPhone 4上，评分最高的应用是“ Viseu – Guia da Cidade”，而在Wiko GOA上，它是“ JiTT.Travel Funchal”应用。反过来，在iPhone 6 Plus，iPhone XR，诺基亚5.1和OnePlus 6设备上，“ Viseu – Guia da Cidade”，“ JiTT.Travel Funchal”和“ TUR4all”应用程序则获得了最佳效果。关于同一移动操作系统的不同版本上的移动应用程序的可访问性，得出的结论是，在两种操作系统（iOS和Android）上，它们的可访问性均没有差异。最后，关于具有不同屏幕尺寸的智能手机上应用程序的可访问性，它们的可访问性也没有差异。“ Viseu – Guia da Cidade”，“ JiTT.Travel Funchal”和“ TUR4all”应用程序获得了最佳结果。关于同一移动操作系统的不同版本上的移动应用程序的可访问性，得出的结论是，在两种操作系统（iOS和Android）上，它们的可访问性均没有差异。最后，关于具有不同屏幕尺寸的智能手机上应用程序的可访问性，它们的可访问性也没有差异。“ Viseu – Guia da Cidade”，“ JiTT.Travel Funchal”和“ TUR4all”应用程序获得了最佳结果。关于同一移动操作系统的不同版本上的移动应用程序的可访问性，得出的结论是，在两种操作系统（iOS和Android）上，它们的可访问性均没有差异。最后，关于具有不同屏幕尺寸的智能手机上应用程序的可访问性，它们的可访问性也没有差异。
