I have tried three different meditation apps and found all of them have very good points. The first app I tried was called Headspace. It is well organized, habit-forming, and I like Andy Puddicombe’s voice (he’s the founder of Headspace and does all the guided meditations). He also did a TED talk which I suspect increased his visibility and gave his app a big boost. The only complaint I have about headspace is that it is very expensive. It costs $13 per month (though they have discounts for longer-term subscriptions). Their lifetime membership cost is $400. For me, it was worth it for one year to learn the skill, but not worth it for multiple years.
Brain.FM is a browser/mobile app that plays binaural beats while you work so that you can focus better. Binaural beats are an odd perceptual phenomenon. If you play two sounds that have almost the same frequency, the interference between the two waveforms makes what is called a beat frequency (beat frequency youtube demo). Here’s the weird thing: if you play one tone into your left ear, and a second tone into your right ear, you perceive the beat frequencies despite the waves not physically interfering with each other. Our brain reconstructs the beat frequency from the difference between the two tones. Supposedly, if that beat frequency matches certain brainwave frequencies, it can induce certain moods and mental states.
I don’t know if that is going to work for everyone. There seems to be some evidence that binaural beats do affect brain waves. It does seem to help me: there are different binaural beats for sleep, focus, and meditation. All of them seem to perform as advertised for me. The brain.FM app also has several guided meditations that I find useful. I got the lifetime subscription to brain.FM with a discount code; that offer seems to have expired, but there do seem to be other discounts available from time to time.
The third app I tried for meditation is Calm.com. The app can act as a background noise generator. It can make the sound of splashing water or wind through the trees (and several other pleasant sounds). I liked those when I was working in a shared office and needed some background noise to help me tune out distractions. They now offer several guided meditations and “sleep stories.” I’m excited to try sleep stories. I guess it’s like a meditative bedtime story to help you go to sleep. I usually don’t fall asleep well if I can hear talking or music. Still, I have found that a relaxation exercise before bed does help me sleep.
Bonus: I have also tried the insight timer which has a simple timer with chimes at regular intervals. It also has community-uploaded guided meditations. A few of those are good but most of them have a lot of ambient music that I don’t like very much (think sitars, zithers and didgeridoos).
