To design an app that helps nursing students to acquire and retain knowledge of Basic and Advanced Life Support techniques, as well as analyze the students' gamification experience. The study had two phases: 1) App design and development and 2) experimental study. A total of 184 students participated, with 92 in the experimental group and 92 in the control group. The instruments used were the Guess it (SVUAL) app, a test on knowledge and the Gameful Experience Scale. The app was deemed to have a suitable level of content and user-friendliness of 97%. The experimental group obtained a higher average score on the knowledge test than the control group (U = 2835.500; Z = -3.968; p < 0.05). On the re-test, the experimental group also obtained a higher average score than the control group. As for the experience within the game, all the dimensions scored higher than average, except the absence of negative effects dimension, which indicates that the app had very few negative consequences on the participants. The developed app has proven to have a good level of content and to be user-friendly, improving knowledge levels and retention of information in nursing students.
