I have been using the Calm App for a really long time now. I think it is such a great app and eye pleasing one at that. It can really help put your mind at ease and help with overall well-being. If you feel stressed, anxious, if you have trouble sleeping or relaxing or if you are simply looking for ways to help you learn how to meditate or simply slow down and be present. It can help with that. Some part of the app are free but to use its full capacity you do need to pay. They do offer monthly or yearly subscription plans. They also offer free trial so if you decide it is not for you, you don’t have to pay.
Honestly a good app that I would highly recommend.
