Table 3.
App usage based on app mental health focus (N=93).
| Mental health focus | Apps, n | Installation category, median (IQR) | Open rate (%), median (IQR) | Daily number of sessions per active users, median (IQR) | Daily minutes of use per active user, median (IQR)a | |
| All apps | 93 | 100,000 (90,000) | 4.0 (4.7) | 3.28 (2.53) | 13.03 (14.27) | |
| Mental health problems | 59 | 50,000 (90,000) | 4.0 (5.1) | 3.77 (3.15) | 10.02 (10.60)* | |

Anxiety | 19 | 10,000 (40,000) | 2.6 (2.5) | 3.58 (3.49) | 08.17 (09.42) |

Depression | 4 | 100,000 (50,000-100,000b) | 4.8 (3.0-6.8b) | 5.22 (3.97-6.55b) | 06.97 (02.05-15.12b) |
| Happiness | 8 | 100,000 (50,000) | 3.7 (5.3) | 3.50 (4.18) | 7.77 (6.90)* | |
| Mindfulness/meditationc | 26 | 100,000 (650,000) | 4.1 (3.3) | 2.96 (1.66) | 21.47 (15.00)** | |
aCategories with different number of asterisks (*, **) within a column are significantly different (P<.05) based on our analytical approach, which included Kruskal-Wallis one-way ANOVA at the variable level, followed by Mann-Whitney U tests.
bDue to a small number of included apps, brackets in this cell reflect the range (minimum-maximum value) and not the IQR.
cMindfulness/meditation is presented as a separate mental health focus because all apps in this category were not attributed to another focus as they focus on enhancement of well-being as well as stress reduction.
