I have 3 similar apps and they all have it. Very disappointing! ### 4/5 — New to the app *2025-07-29, version 1.3.2* I just got the app, want to ask do I need to headset for the app to work? Or is headset optional? ### 2/5 — Bad Redesign *2025-05-28, version 1.3.1* The new redesign removes the option to turn background noises such as fire, ocean, rain, etc. on or off. ### 1/5 — Um, instructions would be nice… *2025-01-09* And options — options would be nice as well. I got the so-deemed lifetime unlimited plan but haven’t a clue how to do anything with it, except maybe change colors (of something?) and listen to a single sound (frequency?) called Rain. That’s all I’ve got. Glad I didn’t pay a cent for this trash. ### 1/5 — Scam in disguise *2024-12-24* I thought for sure I’d be able to download and at least listen to the sound 111 hz, but your app doesn’t offer 111hz, and the worst part of it is one can’t listen without having to pay first. If this is the future of our world what a terrible world it is going to be. Y’all should just be ashamed of yourselves for putting this out in the marketplace, how were you able to get a Service mark and Trade mark? You probably need to be investigated..back in the day, the Secret Service would investigate this. ### 2/5 — Unreliable *2024-08-16, version 1.1.1* The app keeps cutting the sound off even if you have a timer set. ### 1/5 — Stop in background *2024-07-21, version 1.0.13* I cant listen, after a minute stop. ### 2/5 — $100 to play a single tone? *2024-07-12* Maybe I’ve missed something here but it appears that this app lets you select 3 tones, and then you select one and play it with or without a timer. That’s it. I can do that with a quick google search and a frequency generator app on this same phone for free. If it had anything else… binaural capabilities, isochronic capabilities, hemispheric sync, spatial placement controls… anything else, I’d have given a much higher rating. On the positive side, the app design and UI is lovely. ### 2/5 — Wrong Numbers Displayed *2024-07-12, version 1.0.13* This app simply has the wrong number for every frequency - just check with a couple a free tone generators on line - if you could input the number on the app, you could match it with the web sites, but unlike the FREE generators this app’s frequencies are preset . I mean to put this app out there with wrong numbers, didja think no one would check? Could have been good, but it fails ridiculously badly when it gives you a number for a frequency, AND THE NUMBER IS WRONG, how could you put this out with such a glaring discrepancy? Oh well, back to YouTube- DONT BUY TILL THEY GET IT RIGHT ### 1/5 — No Instructions!!!! *2024-07-11* Awful app!!!!! No instructions at all!! Going to settings only allows you to change colors. Ridiculous!!! How do you choose which modes you want like sleep, focus, ect? This app is just the worse app!!!! I shouldn’t have to go to google to do a search on sound frequencies for different modes in order to use the app. Terrible design for the app. This isn’t worth 1 penny!!!! I got the lifetime version of this app for free through the Apps are Free app. So why do I only have the option for Rain and nothing else? Why can you only choose frequencies of none, mid and high? Why can’t you choose a frequency inbetween mid and high? You should be able to choose the exact number for frequency. I have the lifetime version, for free through apps are free app, yet my only option is Rain. That isn’t right!!!! Terrible app!!!!! ### 1/5 — Awful App. Worthless. *2024-07-11* This is an awful app. Totally worthless. What are the developers thinking. Seem like it is on AppAdvice to artificially increase downloads. No options to speak of. Awfully harsh sounds. This will drive you mad, not help you. Far, far better ones out there. Don’t wast your time. Would only let me set a sleep timer and change the colour. Apart from that the only option was two frequencies, and rain or no rain. Junk. Deleted. ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t work *2025-12-12, version 1.3.9* I can’t even pass by the initial I boarding it doesn’t work on iPhone SE ### 1/5 — 这个骗钱，根本没有退订功能。千万不要安装！ *2025-11-09, version 1.3.8* 这个骗钱，根本没有退订功能。千万不要安装！ ### 1/5 — Timer doesnt work *2025-09-15, version 1.3.6* I set the timer, and no matter what I set it to, it shuts off after 30 seconds ### 1/5 — Fake Markating *2025-09-01, version 1.3.5* I got a post from reddit Lifetime plan is now free 🆓 but it’s fake This is vary bad😡 ### 1/5 — Scam *2025-06-11, version 1.3.1* Two days after subscribing for the trial version I couldn’t cancel or get a refund!! Not using this app at all and had to pay! Total scam ### 1/5 — New update *2025-04-29* Well you did it after the latest update I can’t choose the frequency that was changing my life. Bring it back please. **Developer response:** We'll be adding more frequencies soon! Sorry for the trouble. Please do me know which frequency you were using. You can contact me on akanksha@appmasters.co ### 1/5 — XXXX *2025-02-27, version 1.2.7* Están mal calibrados los audios Hz ### 1/5 — Wrong subscription *2025-01-17, version 1.2.4* Every time I try to install asking for subscription, as I subscribed for life, the app subscription method has to be fixed, unless this procedure has been made in purpose. So please fix your app ### 1/5 — One screen with 4 sound options!! I can’t believe I paid money for this! Terrible scam!! *2025-01-16* $10 a month for a single screen with a few sound options, like rain and fire and harder rain! There are free apps that do three times what this one does! Oh, but you can change the color of the screen background, which is a useless feature. Don’t waste your money. I’m so mad I did! ### 1/5 — Trash *2025-01-10, version 1.2.4* Trash ## Most praised reviews (10 highest-rated) ### 5/5 — Reliable app *2025-09-05* I’ve tried a few apps, but this one makes it easy to generate any frequency hz I need without overcọmplicating things. **Developer response:** Thank you for your feedback. ### 5/5 — Relaxing to use *2025-08-31, version 1.3.5* I like the frequency healing sounds in here. I put them on in the evening and it helps me unwind. ### 5/5 — Straightforward app *2025-08-30, version 1.3.5* Pick a hz, hit play, and it works. No extra steps, which I appreciate. ### 5/5 — Works just right *2025-08-27* This frequency generator does exactly what I need. Easy to set up and the tones sound clean. ### 5/5 — Reinfall *2025-02-18* Das ist ein Reinfall und hat nichts mit den originalen Delta Wellen zutun die in den Studien es gibt lass euch nicht Täuschen das sind irgendwelche Sound die garnichts damit zutun haben die echten Delta Wellen aus den Studien sind sind nicht hörbar und haben nichts mit so nem Sound zu tun der nur wuuuuuuuuuuuuu macht .. ### 5/5 — Easy to use. Needs higher freq. *2025-01-26* Works well. Easy to use interface. Would like to see option to go up to higher frequencies (up to 15 kHz) to help with Tinnitus. Contact info on website didn’t work. **Developer response:** Okay we'll work on this. Thanks! ### 5/5 — Top *2025-01-20* Gostei ### 5/5 — It took forever to while updating (Deleted) *2025-01-19* Hope you guys fix the issue. And thanks for the application. ### 5/5 — Well designed *2025-01-16* The app functions as it’s designed to. You have three top tabs ‘Low / medium/ High’ The central dial commences at 0, you turn the dial and select the hertz you prefer. Low can go up to 50; medium can go up to 95, and high can go up to 963. The developer also provides 3 sound options or silent located at the bottom left. The app can also run in the background while you do other things. It even has a timer and lets you choose different colors. A safer way to listen to frequencies without the possible subliminal insertions I’ve found on certain channels. ### 5/5 — Thank you for the Free Lifetime Subscription! *2024-07-11* I can’t wait to try this out! Thank you for making the Lifetime Subscription available for free today through App Advice Daily. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
