I haven't tried calm before. It sounds good that it has multiple types of meditations in it. I have a Headspace subscription and it works well. It's a lot better than my earlier attempts at meditation when I was younger. I looked into Buddhism for a while as a teen and their meditation was all about reaching Nirvana (the state where you stop producing karma, not the band) which meant it was focused around "not thinking". As a teenage girl with ADHD (undiagnosed at the time) that was impossible and just got frustrating. I might as well have been trying to shoot fireballs out of my hand.

Headspace uses guided meditations and has actually been quite useful unlike the "stop thinking" style of meditation.

I also downloaded a meditation program for our Oculus Rift (VR headset) but I haven't tried that out yet. I'll have to sometime. Most of the headspace ones have you do some of it with your eyes open but ultimately close your eyes during the meditation, but I'd assume in VR you wouldn't close your eyes (otherwise why be in VR), so I imagine that will be a completely different experience again. Not sure what it will be like but it is definitely worth a try.
