When you just want to turn your brain off and sleep, meditation apps are perfect. A guiding voice, or the sounds of something peaceful such as rain, helps to fill the silence so your thoughts can’t creep in. The best ones strategically bore you into drowsiness. (You can look for sleep-focused meditation tracks, but I’m guilty of misusing the Headspace intro lessons for this purpose.)

iOS/Android: When I run, my inner monologue sounds like an argument between a good coach and a bad coach. One voice tells me to take it easy, find my best pace, not to look at my watch, just find the right level of effort. Then the other voice butts in to say something like "Oh, look at you, running so slow, and you're already tired! You suck!"

Android/iOS: If you've ever been a paying Headspace customer, you know the tyranny of the Packs. A pack is a course of meditations, each building on the next. But if you were working through the Anxiety pack, and wanted to check out Creativity one, you'd lose all your progress. Until today.
