Parents need to know that Breathscape: Deep Breathing uses your phone to provide biofeedback through guided breathing and/or meditation. The developer cites research that indicates that deep, slow breathing has great health benefits and can help improve sleep quality, reduce stress, and even reduce or lessen the affects of migraines. It wasn't designed specifically for kids, but there's nothing that would make it inappropriate for them. Breathscape: Deep Breathing was clearly optimized for use with a smart phone, it could also work with a tablet or iPod. As the in-app instructions demonstrate, users place their phone on their belly and follow music or guided instructions as they focus on their breathing. As the phone detects motion, the music responds and the app collects data on the user's breathing patterns. It's not necessary to create an account, though the developers offer some additional functionality if users sign in.
