Want a longer, happier life? Consider using apps

Many apps support activities that promote emotional well-being. Happiness apps feature affirmations, meditations, or gratitude journals. Exercise apps track daily physical activity or provide workouts. Meditation apps guide users through various kinds of meditation, such as mindfulness or guided imagery. Sleep apps help people track how long they sleep, and offer instruction to improve sleep hygiene—such as going to sleep and waking up at the same time each day, and avoiding food and drinks at certain times.
