Ooooo

Love that I can completely customize the frequencies, tones, and noise type - and that I can also play music or listen to podcasts while it’s on - although I tend to use it on its own most of the time. My top pick for improvement would be full shortcut support - but as it is the app supports URL calls so I have this automatically start playing when I initiated a focus mode, and stop when I turn off the focus mode - it just ends up opening the app everytime. I do think some ready made configurations or configurable presets would be great, as well as the auto-pilot feature another reviewer mentioned - but that’s icing on an already great cake. Thank you to the developer for making this app free, simple & effective. Really appreciate it.

Just found this app. I have tried and still use lots of apps to help me sleep, concentrate, and relax. Oooo is amazing! Right away I loved how customizable it is. As soon as I picked a frequency and then adjusted the tone I realized how important it is to be able to adjust these things for yourself. As I adjusted the tone, I was able to pick something that felt soothing. It just felt “right”. I’ve only had this app for one day and I already plan on recommending it to family and friends.

I never write reviews, but I feel compelled to for this one. I’ve tried a dozen or so binaural beats apps. Ninety nine percent of them are loaded with battery draining ads / graphics and designed like a teenager’s identity crisis — typically either patchouli-stank chakras and crystals, or edgyXcore cyberpunk aesthetic (you know the one I’m talking about). This one stands out. It has all the features you need, and none of the stuff it doesn’t. The only thing it’s missing is something to tell you which brain waves you’re stimulating (alpha, theta, etc.) The ability to ramp frequencies up and down over time would be great too, but even without those features, this is all the app you need. It’s simple, clean and functional.
