App won't open.

I just downloaded it, and it won't open at all? I've reinstalled twice, same thing. And I've restarted my phone, checked for phone updates.. Nothing works?

Not teen/adult friendly

It uses writing only for a very long time when you sign up. People want to play with apps and listen to sleep meditation stories, but this app makes you read lots of writing without many animations and forces you to do “training” rather than fun and helpful sleep activities. It’s really boring and wouldn’t appeal to teens.

Hi there, Thanks so much for reaching out and we’re sorry to hear that you find the app too text-heavy. The training is designed to build lasting improvements to users’ sleep habits that continue to help over time. If this isn’t what you’re looking for – we do have a meditation track in the ‘More’ section of the app!

Won’t let me open!

I tried using this app and it won’t let me open it, as soon as I click it immediately sends me out, I delete and re-download AND reset my phone.
