I’ve shared it with many friends. I think the grounded and centered feeling it promotes is in part because not only the tones soothing and calming, but also they never increase in volume, never have a “beat” to them. Besides listening to them with intention, I have found these tones to be a lovely background sound to have on when with a friend who is sharing something deep or personal. I can’t recommend this app highly enough! ### 2/5 — I guess *2024-07-03* From 1.99 to 3.69 a month. It’s just not worth it… so many similar things. ### 1/5 — App doesn’t open *2023-12-03* Downloaded, signed up, got an email with link to Launch which takes me to a QR code to download app, sign up, get an email….????? ### 5/5 — Profound *2023-07-27* I was skeptical with all the free meditation apps available out there but something about the way they make these tones is just beyond. It’s weirdly transformative. I find myself listening every single day. Thank you. **Developer response:** Thank you Scrunchie22! Yes, daily listening is transformative. Try taking the ToneStream on a walk with earbuds. Transforms the world around you! Cheers, Michael Joly, Founder, Solu. ### 5/5 — So great *2023-07-17* This app is wonderful and addictive in the best way, but I think you would get many many many more subscribers and make this magic accessible to way more people if you lowered your prices a little. ### 2/5 — What happened? *2023-03-03* Last year the app was free with the option to donate. Now it’s subscription without any notification other than the screen saying that your free trial is over. Sooo not cool. I recommended it to others. I feel like it is just another bait and switch. **Developer response:** Hi there, thanks for your comment. We found there were not enough paid subscribers to continue to offer the Solu ToneStream service to all who were using it for free. Our mission is to bring peace and healing to the world, through sound––as a heart based company. We don't have any in-app advertising, or in-app pitches to purchase––only a gentle, tone-based meditation experience. We have un-recouped development costs and have on-going streaming and developer labor expenses. We know we're offering a valuable service and we're simply asking folks to try it for 1 month, for free. If it resonates with them a $1.99 / mo. subscription for the benefits of more peace, more unity and better sleep is a small price to pay for those life-changing benefits. I hope this explains why we changed our subscription offer. Thanks for your understanding. Best, Michael Joly, Founder, Solu ### 1/5 — This is misleading *2023-02-16* I am currently requesting my money back from apple. The app is misleading in so much as you think it’s a one off payment so you accept the payment in the belief that you only have a one time charge. Then once you download the app and have already paid you then have to make monthly payment. This is a con in my opinion and had I known this from the beginning I would not have downloaded it. It has not been marketed properly. ### 5/5 — Best app ever!! *2023-01-17* I love love love this app! I have ADHD and struggle to read and relax in general due to the background noises . Not anymore!! It’s so relaxing that my brain doesn’t register it as “noise” only relaxation that is so subtle that I don’t even notice it’s there!! It helps me read, relax, and sleep. I use it everyday, I can’t give this app enough stars. ### 2/5 — Not happy with latest update *2023-01-17* You have to subscribe now. Before, it was completely free. Not really thrilled with the change. Was a great program I would use all the time as I could not always have my n.o.w. Devices with me. **Developer response:** Hi there, thanks for your comment. Our mission is to bring peace and healing to the world, through sound––as a heart based company. We don't have any in-app advertising, or in-app pitches to purchase––only a gentle, tone-based meditation experience. We have un-recouped development costs and have on-going streaming and developer labor expenses. Users tell us Solu is offering a high value product (n.o.w. Tone Therapy System our $179 hardware mediation device) and service (and Solo ToneStream Mediation app) We're simply asking you to try Solu ToneStream Mediation it for 1 month, for free. If it resonates with you then a $1.99 / mo. subscription for the benefits of more peace, more unity and better sleep is a small price to pay for those life-changing benefits. I hope this explains why we changed our subscription offer. Thanks for your understanding. Best, Michael Joly, Founder, Solu ### 5/5 — Grounding and cleansing *2022-11-18* I’ve downloaded countless meditation and sound apps, only to delete them a few days later. Solu is by far my favorite one. It took no time to set up, you can choose how much, if anything, to pay for it, and there are no ads even if you have the free version. The moment I started it, my senses focused on it and the chatter in my brain stopped. It feels like a warm bath for the soul. So grateful to have found it. ## Frequently asked questions about ToneStream ### What is Solu ToneStream's subscription cost? Solu ToneStream is offered at a fixed price of $3.69 per month.
