I’m not sure why but it doesn’t. Writing from USA idk if that impacts anything ### 1/5 — Registration *2019-01-17* App won’t let me register!?? ### 1/5 — Junk *2018-09-06* Hardware is horrible. Interface on the software is junk. You’re better off with a free white noise program some headphones and a washcloth for a blindfold ### 3/5 — great idea, but... *2018-03-10* I would enjoy this app/hardware so much better if you could turn off the music - I could easily nap to the sound of the rain, but with music it’s much harder. ### 1/5 — Crashes on my iPhone X *2017-12-31* Can’t use this app at all ### 1/5 — Can't be worse! Why there's no 0 stars mark? *2017-09-06* Needed some rest and nap, badly. After Naptime app launch, got message that I should upgrade to new version. Was stupid enough to do that. Now app crashes every time I try to run it. Thanks for ruining the evening! ## Frequently asked questions about Naptime ### What is Naptime's main function?
