Sunlight is a meditation app that can literally read your mind.
The interface is intentionally left very simple. Your meditation practice grows a beautiful plant. You'll meditate with your plant for 21 days to grow it fully - that's about how long it takes to form a new meditation habit! Hopefully, after the plant is grown, you'll be on your way to being a regular meditator.
The app (optionally) uses a NeuroSky headset.
