সারসংক্ষেপ	A Mobile Research Diary is a data collection technique in which participants record thoughts, experiences, behaviours, or events in structured diary entries submitted via a smartphone or tablet app over a defined study period. By moving the diary onto a mobile device, researchers gain time-stamped, geolocation-optional data captured close to the moment of experience, reducing retrospective recall bias while maintaining the rich, naturalistic quality of traditional diary methods.	Mobile Experience Sampling (ESM) is an intensive longitudinal data-collection technique in which participants respond to brief, repeated questionnaires delivered to their smartphones at random or scheduled intervals throughout the day. By capturing thoughts, feelings, behaviors, and context at or near the moment they occur, ESM minimises retrospective recall bias and provides a high-resolution picture of psychological and behavioral fluctuations in everyday life.
