Results: Overall, six trials (486 participants, 66.7{\%} [324/486] women; age mean 68 [SD 6] years) were included (five of these trials were included in the meta-analysis). mHealth app interventions may be associated with decreases in sedentary time (SMD=−0.49; 95{\%} CI −1.02 to 0.03), increases in PA (506 steps/day; 95{\%} CI −80 to 1092), and increases in fitness (SMD=0.31; 95{\%} CI −0.09 to 0.70) in trials of 3 months or shorter and with increases in PA (753 steps/day; 95{\%} CI −147 to 1652) in trials of 6 months or longer. Risk of bias was low for all but one study. The quality of evidence was moderate for PA and sedentary time and low for fitness. Conclusions: mHealth app interventions have the potential to promote changes in sedentary time and PA over the short term, but the results did not achieve statistical significance, possibly because studies were underpowered by small participant numbers. We highlight a need for larger trials with longer follow-up to clarify if apps deliver sustained clinically important effects.
