absolutely love this app! i depend on white noise as background noise due to sound sensitivities and this app runs it perfectly! i love that running the sound in the background is a free option, where as most apps make you pay for that, or it doesnt work. i switched to this one for that reason and i dont plan on going back! also not to mention the variety of sounds that are free and even more if you pay the subscription. keep doing what you're doing the way you're doing it!

Dev is very responsive to feedback, and will look into adding my sound suggestions to the sound collection! Slo also offers a monthly plan opposed to Bettersleep who only offers yearly plans. I was looking for a sound app that had a variety and abundance of different sounds, adjustable volumes, and the ability to mix them up. Looking forward to the sound additions in the future.

here recently you have put out several updates but given absolutely zero context as to why the updates were released. I have set the app to not update on its own, in the future some sort of explanation would be nice because every other app does it whenever there's an update like what they're doing, bug fixes you're adding new sounds, whatever the hell, why don't you give us the same courtesy?

Hey, recent update included a bunch of new sounds that you can find in the app and also improved the way it keeps playing the audio overnight, other than that it's usually bugs and fixes or requirements from Google to update the app. Btw. 2-star review is really demotivating and hurts my app (I'm building it solo and simply have no time for it)
