The overall aim of the study was to examine the effect of individualized follow-up with an app for one year on peak oxygen uptake (VO<jats:sub>2peak<\/jats:sub>) in patients completing CR. <\/jats:p><\/jats:sec><jats:sec><jats:title>Design<\/jats:title><jats:p> The study was designed as a single-blinded multicentre randomized controlled trial. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p> The intervention group (IG) received individualized follow-up enabled with an app for one year, while the control group (CG) received usual care. The primary outcome was difference in VO<jats:sub>2peak<\/jats:sub>. Secondary outcomes included exercise performance (time to exhaustion, peak incline (%) and peak velocity (km\/h)), bodyweight, resting blood pressure, lipid profile, triglycerides, exercise habits, health-related quality of life, health status and self-perceived goal achievement. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> In total, 113 patients completing CR (73.4% with coronary artery disease, 16.8% after valve surgery and 9.8% with other heart diseases) were randomly allocated to the IG or CG. Intention to treat analyses showed a statistically significant difference in VO<jats:sub>2peak<\/jats:sub> between the groups at follow-up of 2.2\u2009ml\/kg\/min, 95% confidence interval 0.9\u20133.5 ( p\u2009&lt;\u20090.001). Statistically significant differences were also observed in exercise performance, exercise habits and in self-perceived goal achievement. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> Individualized follow-up for one year with an app significantly improved VO<jats:sub>2peak<\/jats:sub>, exercise performance and exercise habits, as well as self-perceived goal achievement, compared with a CG in patients post-CR. There were no statistically significant differences between the groups at follow-up in the other outcome measures evaluated.
