Addiction recovery is a deeply personal journey of lifelong learning (LLL). Mobile technology is considered the choice technology for LLL, particularly in situations related to personal health and life transitions. This study addressed everyday experiences of using mobile devices for LLL to better understand non-technological factors that make mobiles a choice technology for LLL. This study used a qualitative, phenomenological design to understand uses of mobile technology for LLL in addiction recovery and its perceived impact on their recovery. A purposeful sampling method was used to identify six participants. The population consisted of adults who self-identified as lifelong learners, were in addiction recovery for greater than one year, and reported using mobiles to support their informal LLL. From the interviews, 11 themes emerged: (a) it is a daily kind of thing, (b) it just kind of happens, (c) it has a lot to do with mindset, (d) it has to do with exploring different options and ways of doing things, (e) it has to do with asking myself questions and personal reflection, (f) it supports feeling good and positive, (g) it supports feeling visible again, (h) it supports connection with self and others, (i) it helps me hold myself accountable, (j) it helps me see the changes and believe the progress, and (k) it helps me no longer feel like recovery is a separate part of life. Conclusions drawn from this study included the perceived value of mobile devices as recovery tools, the importance of informal learning on recovery, the self-determined nature of mobile LLL processes, and the ways that mobile LLL supported recovery. Additionally, the self-determined nature of their LLL processes were examined using a heutagogical lens. Additional research on supporting self-determined LLL with mobiles in addiction treatment may enhance long-term outcomes. Moreover, additional studies on mobile LLL in highly informal learning environments (like addiction recovery) may help to deepen the understanding of how mobile devices may be used to maximize learning.
