I find Calm a very good and special dose! Last year i listened Calm when i was on holiday. I told my mother that i would listen 15 minutes (the dose takes 15 minutes). I was listening it and i found that it had very relaxing and beautiful sounds. After 25 minutes my mother woke me up and i discovered that i felt asleep while listening.The i turned off my phone and went to sleep. The next day (evening) i listened it again and i felt a little bit asleep again. Now i am still listening it sometimes and i get very relaxed and calm while listening it. I still find it have very special sounds. I find that it have something magic. I really recommend this dose to everyone that want to relax or calm! I also find the Reset dose a very good dose and very handy! I have not yet listened Condition and Alert but i find it handy to have it and will probably try it later. I find it really a must have pack and i recommend everyone to buy this pack! Thanks for making this doses I-Doser!
