App for lost and found, developed in Porto, Portugal. iFound was created based on the fact that the human brain and its memory capacity have several flaws. Forgetfulness is part of adult life for various reasons such as worry, stress, fatigue, or possible health issues, and can even be genetic. According to a survey conducted in the United Kingdom, the five most commonly lost items, in descending order, are: cell phones, house keys, car keys, important documents (related to work/studies), and finally, prescription glasses and sunglasses. The average number of lost items per respondent was nine, which corresponds to nearly 3,300 lost items per year. By publishing a post about the lost item and offering a reward to whoever finds it, the app encourages other users to contribute to a common good: returning the item to the person who lost it. To complement our application, its second core feature is functioning as a reminder—encouraging the user, as often as they wish, to do a check-up of all important items they carry with them. This way, if something does go missing, the search area becomes smaller, significantly increasing the chances of finding the item while reducing the effort and energy required. Another complementary feature of the app is a "pop-up" alert, sending real-time notifications to all users on the network to highlight "red alert" situations. This becomes a powerful social tool for scenarios such as missing children, car theft, or missing pets. In this way, our application not only expresses a strong sense of responsibility and social improvement, but it can also assist in critical and high-interest situations, contributing to a better society.
