I can't stop recommending this app! I have tried all the main meditation and mindfulness apps, and all have their downsides. I am yet to find one here. The content is so well curated, it is quick and easy to find exactly what you are looking for, when you need it. There is something for all levels of experience, and no assumptions are made that you must have any prior knowledge, without being the slightest bit patronising. There is also a really generous amount of free content available.
