In the past, travelling from point A to B could be a tiresome enough job, let alone traveling abroad.
Today, wheelchair users and other travellers with disabilities have the chance to travel overseas, set sail on a cruise or take a drive across country to Grandmother's house. However, disabled vacationers surely recognise that there'll still be additional challenges while travelling.
Mobile travel apps can significantly improve a travel experience for disabled travellers by providing information about accessible transportation, accessible city attractions, museum access guides, etc.
The problem is that both iOS and Android do not allow simple and intuitive search of travel apps for cities and countries.
