Looking forward to being able to listen to this great relaxation app again! ### 5/5 — Love Love Love *2014-10-11, version 1.0* I have all of the Solfeggio apps from Glenn. They are the absolute best and my most favorite of any to date. Please fix the iOS 8 software as soon as you can, I am having withdrawal symptoms! Thank you for such great apps. Patiently waiting.... ### 5/5 — Love it! *2014-10-09* Hi there! Of course like everybody else I'd lost the apps after I updated the iOS 8. I deleted them from my phone in the hopes that I would be able to download them again and that would work. I only found one frequency and I am sure that the reason is because you're working on the other ones. Is there anyway that I can be notified when the other ones are available? (hoping that by writing this interview you have access to my information?) also I've been listening to Solfeggio frequencies for a while from other artists and after a while I noticed that there are nine frequencies in total? Maybe 6 originals. Do you think you're going to make more available in the near future? I really love your work and the quality of it is just simply wonderful I put it in the morning when I take my walk right after I wake up it's fabulous! ### 5/5 — Great *2014-10-08* I listen to Glenn's Solfeggio Sonic Meditations to re-charge my well being. It relaxes my mind and improves the way I handle the stress of everyday life. After upgrading to iOS 8, all of the solfeggio tones apps stopped working. I know that they are trying their best to fix the problem. I hope for their success to make these apps available for use again. ### 5/5 — I love these apps! *2014-09-21* I have all of the solfeggio apps, love each one. I fall asleep to them every night, and will often listen to the instrumental portions while working. I am in withdrawl with iOS8 causing the apps not to work :) I know Glenn is aware and the problem is being worked on. Once they get it all sorted, I highly recommend these apps. They are well worth the investment as are all his apps. ### 5/5 — Wow puts me right to sleep *2014-08-23* I have two of the healing frequency apps that I alternate before bed. They both work so well I have very rarely ever made it to the end of the track. I frequently have problems falling asleep but these work like clockwork. I'll probably buy all of them. ### 4/5 — Great But Gets Distracting *2014-03-09* This app is effective and works great (relaxing and good hypnosis results), but I wish they would put more focus on the actual solfeggio tone because you can hardly hear it. I would recommend some improvements. Basically, there's way too much going on. Instruments, chants, etc. In a perfect hypnosis session, less is more. Since the point is the solfeggio, all of the other things tend to get distracting. Still, the app is very well done and I've already bought several versions even though my tolerance for the chanting disruption is slowly wearing thin. Also, it would be helpful to know what the actual chant is. It somewhat sounds like Om Mane Padme Hum, but there isn't a translation provided in the info section. If I'm going to meditate on a chant, it's important for me to know its origins and what it signifies. ### 5/5 — Brilliant *2013-10-09* I've never been one to buy into this sort of thing, but Glenn is brilliant. So much positivity emanates after listening, it's remarkable. The state of relaxation and complete peace of mind he lulls you to is so lovely. Not only completely worth the $5, but up there on my list of "best purchases for $5". ### 5/5 — Best ever! *2013-07-29* I've tried lots of guided hypnosis sessions and meditations. This series is the best, by far. I actually feel physical shifts and changes in my body while listening. Glenn's words are powerful and fitting. He states everything in positive terms, which is very important in these types of recordings. The music is magical. I highly recommend this entire series! ### 5/5 — Amazing! *2013-07-05* My children and I fall asleep most nights to these wonderful meditations! I wake up in the exact position that I fell asleep in! Feel wonderful every morning! ### 5/5 — Good vibrations *2013-02-24, version 1.0* Something long held was released on the first listening of this recording. I've meditated for many years, but this music and Glenn's calm direction helped move me beyond the point I was at. ## Most critical reviews (10 lowest-rated) ### 1/5 — Great tracks but very inconvenient app *2020-09-22* Went to use one of the *many* Glenn Harrold apps I own in a remote location. None of them were available. The central store app wants me to Restore every time I want to use a title. I had no cell or internet service available, so I couldn’t attempt to Restore. Apps I purchased years ago don’t show up in the purchased area. So I go back to my icons for my paid apps on my phone and then have to traverse back into the app hub. When I pick my title in the central app hub, it wants me to pay more money again. How inconvenient and unnecessary. Why do my paid apps continue to disappear in the first place? I am not uninstalling them. I just want the apps I paid for to be available on my phone like they always were before the central app listing every app GH has took over my experience. I don’t want to be forced to listen from some connected server or have them go away randomly so I am without their use when I need them. I have spoken to support years ago. They assisted back then but here I am again with all my apps gone. I must have at least 7-10 of Glenn’s programs. He is quite good. The titles back then ranged from $5.95 to $9.95. I don’t look at any possible new options any more due to this chronic disappearing act or being forced to be tethered to the cloud. I don’t want an annual subscription, I just want the apps I paid for back in the day to be available any time; any where; Frustrating! **Developer response:** Hello, Sorry to hear that you are having problems with your purchases. Please contact us directly at sales@hypnosisaudio.com so that we can consolidate everything into Relax & Sleep Well. Kind regards, Diviniti Publishing ### 1/5 — Newly unhappy *2014-10-14, version 1.0* Does not work on iPad iOS 8. Use to enjoy. But no longer..... Developers apparently don't keep up with latest IOS. Everything stopped working. Feel as if I was ripped off having purchased the entire set. Will be pursuing refund if not resolved soon. ### 2/5 — Not great. *2020-11-17* I just wanted the 417 HZ sound. Wasn’t looking for crickets and rain and talking. How am I going to sleep when someone is talking on the audio tracks? **Developer response:** Hello Daniel, I'm sorry the app wasn't for you. If we can help with anything please feel free to contact us directly at sales@hypnosisaudio.com. Best wishes, Diviniti Publishing. ### 2/5 — IOS 8 *2014-09-29, version 1.0* Please fix the problem with iOS 8 and your app because this is not fair when I bought your whole series and enjoyed it immensely and I would like to continue with them ### 2/5 — Voice is too loud *2013-11-15* So the point of this app is the tones. Glenn's voice is too loud for me to hear the tones. If I turn the volume up enough to really let the "tones wash over me" as instructed, the voice would be overwhelmingly loud. I have the volume up enough for his voice to be comfortable- on the verge of being uncomfortable, and at that level I can barely hear the tones. His voice is easy to listen to. I have used the app for 5 days. ### 2/5 — Disappointed *2012-05-10, version 1.0* There are two meditations listed - one for awake and another for sleep- there is approximately 5 minutes difference between the two yet the imagery is exactly the same - so, yeah, it's the same mediation listed twice - listening to the first one was cool but when I went to listen to the second and it was just like the first, well...what is the point of that. ### 3/5 — The voiceover is too loud *2017-09-23* Please add a version without the voiceover. The voice is way too loud. If I knew this beforehand I would not spend $20 on this. Thank you. ### 3/5 — Love it BUT!!! *2014-10-14, version 1.0* Needs update to iOS 8!! Opens & immediately closes. HELP! ### 3/5 — Very Good App! But... *2013-11-03, version 1.0* There needs to be a separate volume control for the vocals vs. the music. I can barely hear the music and there should be a way to adjust this. Fix that and would give it a 5 star rating for sure! ### 4/5 — Remove the crickets *2016-03-07* … I enjoy all of the apps in this series from this publisher. The one thing I cannot stand is the crickets and other animal weird creature noises in the beginning of the programs. Crickets are not relaxing…Please remove those and I will love your work. Thank you… **Developer response:** Hello, thank you for your review and feedback we will take it on board. Please contact us at sales@hypnosisaudio.com if you have any other issues.

I use it with headphones and I do breathing exercises and I’m asleep within minutes.... amazing !! ### 5/5 — Fantastic app *2019-03-12* I'm in my sixties and have tried a lot of relaxation apps. Glenn has the most relaxing voice ever. This one has great vibrations that take me to another world. I have all the Solfeggio Scale apps of Glenn's. Great job Glenn! ### 5/5 — Fairly sure I levitated *2018-08-02* Very powerful imagery and incredible electrifying feelings in my body. This is a magical sonic hypnosis - worth the investment ### 5/5 — Solfeggio Scales *2017-04-12* All of the Glenn Harrold Solfeggio Scales are amazing. I'm just sorry that I have not written a review before now. Everyday I sit & listen to one of these Solfeggio Scales & I can assure you that you will benefit greatly practicing these on a daily basis. Or when you can. I feel like a different person, that's because I am. Think differently,I am healthy, I feel loving towards myself & others. The sounds make you feel so loved & warm it's so divine, a spiritual haven for your soul to be soothed & release old beliefs, thought patterns, feelings etc in such a safe way. Have a note pad beside you & tissues to release emotions that have been stuck over years, days & write your emotions that come out at the end. Very good self therapy! Light some candles, turn off the lights, shut the windows, put a note on your door, pull the curtains drawn, burn some essential oils or incense & begin your very own journey of discovery. Enjoy & thank you Glenn Harrold for helping me change my life around 🙏🏻 **Developer response:** Thank you for such a complimentary review of our 417hz Solfeggio Sonic Meditation app. It is lovely to read how much it is helping you. All the best, Diviniti Publishing. ### 5/5 — Maravilhoso *2017-01-10* Produção esmerada, qualidade incrível.Excelente para meditação. ### 5/5 — My favorite *2016-01-03* This meditation is by far my favorite of his so far.
