Subscription My A***

I used to own this app and it was great… and FREE! Now they charge a monthly subscription. No thanks!!

Most functional sleep app I've found to actually hellp

Great work on this. I love the selection of soundscapes without any marketing gimmicks. For a sleep app, I think investing in the actual soundtracks and to develop functionality around the music is what it's all about when it comes to an app to help you sleep and relax.

If there could be a way to create certain playlists and/or group together existing soundscapes, so for example you don't have "Random" set for the night but something like "Water sounds" tor instance, this would really make a big difference, at least to me.

Can’t use it with my own music?

I don’t mind ads and I don’t mind paying for extra features but the whole point of this app was to use my music to fall asleep and that is now behind a paywall? Not a fan.

Response from developer

I know the custom music is the primary feature of the app, and I would have preferred to keep it free, but after almost year, I can still count the active subscriptions on my two hands. If this doesn’t lead to at least some more subscriptions, I’ll probably just discontinue the app.

Love this playlist app.

There were a couple of hiccups related to my understanding of the new interface, but Lukas, with customer support, was quick and fantastic to helped me find the solutions within a couple email exchanges.
Plus the new additions are super useful. Dozzzer is the perfect solution for my needs and I use it nearly every evening to "wind down" from my day.
