Love the interface and audio engineering choices. Perhaps add timed playlists for longer sessions and soundscapes? ### 5/5 — ZenWave appears (sounds) to be what people want! *2025-03-26* Recommend ### 5/5 — Feature Request: Sleep Timer and Vietnamese Language Support for Zenwave Sounds *2025-03-25* Dear Zenwave Sounds Team, I am a regular user of your app and truly appreciate the relaxing sounds that Zenwave Sounds provides. However, I would like to suggest a couple of features to enhance the user experience: 1. Sleep Timer Feature • I often use Zenwave Sounds for meditation, work, or before sleep. However, the app currently does not have an option to automatically stop playing after a set time, requiring manual shutdown or leaving it running indefinitely. • Adding a sleep timer would allow users to customize their listening time, making it especially useful for sleep and meditation sessions. 2. Vietnamese Language Support • Integrating the Vietnamese language would make it easier for Vietnamese users to navigate and fully utilize the app’s features without language barriers. • This improvement would not only enhance user experience but also expand Zenwave Sounds’ reach in the Vietnamese market. I hope your team will consider these suggestions for future updates. Thank you for creating such a great app! ### 5/5 — Wow! This is THE ONE! *2025-03-25* I’ve evaluated dozens and dozens of sleep apps over 15+ years! This one is THE ONE I’ve been looking for. I’ve long been into brainwave entrainment and this one not only offer various frequencies, but also a huge variety of music and ambient mixes to go with them. Beyond that, I don’t like having to remember what all the various frequencies are known for — no worries here — every track has a description to let you know what you’re getting into before you play it. This has kept me from wasting a good night’s sleep on a track I know I’m likely not going to enjoy and may keep me awake. I also like the UI/UX except it could use some layout enhancements in the area where the sleep timer and breathing controls are located. I would also prefer the description of the track to be at the top instead of having to scroll all the way to the bottom to locate it. All that said, this app, in my opinion, is fantastic. Where you been all my life?!!! Hope the Dev forever keeps adding tracks, new frequencies, and keeps improving it. 5/5 Stars! ### 5/5 — Sublime *2025-03-23* ✨✨✨✨✨ **Developer response:** Hey there and thanks a lot for writing the review! If you have any feedback or problems, feel free to reach out to info@mkgames.org. - best Marvin ### 5/5 — The variety I crave! *2025-03-23* I used to have an app that allowed me to listen to soft music with chimes while also using binaural beats. That app was removed a while back and I have not been able to find an app with sounds and beats that matched what I had with it. Until I downloaded this app. The variety of different wavelengths and sound patterns give me the range I need, whether I’m working through a mound of paperwork or trying to relax before bed. **Developer response:** Hey there and thanks a lot for writing the review!

Thank you for making this app. **Developer response:** Hey there and thanks a lot for writing the review!

I have often wanted to play binaural sound music, but just couldn’t find a comfortable mix between ambient sounds and the binaural sound on YouTube. I have full control in this app to control the volume of each independently, in addition to a timer if at bedtime. Another absolute gem - there are two different listening options…one through stereo speakers/headphones and the other just through your device’s speaker. During the day, I would use headphones, but at night, it’s great to have have playing through my phone and shut off after a specified time limit. Finally, if you do not want to hear either the binaural sound or the ambient sounds, they can be shut off completely independently. There are so many options. This is my favourite app purchase this year so far. **Developer response:** Hey there and thanks a lot for writing the review! Really appreciate your comment and hope you'll continue to enjoy ZenWave.

You are able to change the beat volume and the ambient volume, and there’s a timer. I need to do some more exploring though. **Developer response:** Hey there and thanks a lot for writing the review!

Recommended! **Developer response:** Hey there and thanks a lot for writing the review!

If you have any feedback or problems, feel free to reach out to info@mkgames.org. - best Marvin ### 5/5 — Nicely done and organized *2025-03-22* Easy to queue up sounds, and the sounds/ music are categorized in a way that does energize me or help me relax for sleep. I like the offline and timer modes. The app is easy to use and browse. This is something that I will come back to for complementing my meditation practice and/or helping me rest for sleep. **Developer response:** Hey there and thanks a lot for writing the review!

With ANC headphones, it can be extremely refreshing **Developer response:** Hey there and thanks a lot for writing the review!

Die wurde ohne Angabe von Gründen gelöscht, ist hier nicht mehr auffindbar…. Sowas geht gar nicht, dafür würde ich direkt noch -5 Sterne geben!!! Kein Wunder, dass es hier nur 5*-Bewertungen zu lesen gibt… Also dann noch mal: Ich kann die App nicht empfehlen. Kein Probeabo möglich, Jahresbeitrag wurde direkt abgebucht. Trotz Premiumabo beim Öffnen der App direkt die Aufforderung Premium zu kaufen. Meditationen mit Anleitung sind nicht zu gebrauchen weil man dabei lesen muss. Und bevor die Entwickler wieder schreiben, ich bewerte die falsche App, NEIN, mache ich nicht, habe nur diese eine Meditationsapp!! **Developer response:** Wegen der Löschung musst du dich an Apple wenden, damit habe ich nichts zutun. Apple markiert manchmal Bewertungen als Spam und löscht sie nachträglich. Vielen Dank trotzdem für dein ausführliches Feedback. Schade, dass du mit der App unzufrieden bist. Um das (nochmal) klarzustellen: Ein kostenloser Probezeitraum ist beim Wochenabo enthalten – wie auf der Paywall deutlich lesbar. Das Jahresabo hat keinen Probezeitraum, was dort ebenso klar angegeben ist. Sofern man lesen kann, sollte das direkt ersichtlich sein. Ansonsten würde Apple die App auch nicht für den Store freischalten. Auch der Vorwurf, dass die Paywall nach dem Kauf weiter erscheint, ist schlichtweg falsch: Sobald Premium aktiviert ist, wird die Paywall nicht mehr angezeigt. Das habe ich vorhin nochmal getestet. Falls du dennoch Probleme hast, hilft ein kurzer App-Neustart – oder der Support, den du leider nicht kontaktiert hast. Übrigens handelt es sich bei der App um Audio-Inhalte mit binauralen Beats – also keine klassischen geführten Meditationen mit Vorlesetext. Das steht übrigens auch in der Beschreibung. Dein Feedback scheint für mich nicht mit der App zusammenzuhängen, denn bei dieser App geht es ausschließlich um die entspannenden Geräusche und die Binaural Beats. Alles Gute weiterhin und viel Erfolg auf deiner persönlichen Entspannungsreise! ### 1/5 — Won’t connect via AirPlay *2025-04-12* It won’t connect to any HomePod or AirPlay device in my home. Other apps can, this one only spins. ### 1/5 — ? *2025-01-27, version 3.5.4* Cannot tap the back button ### 1/5 — Free Trial Doesn’t Work—Please Fix *2024-12-31* Free 1-year trial posted on AppAdvice doesn’t work— you can select it as an option, but can forward from that screen to complete the trial. Please fix! **Developer response:** Hey there, this is just not true. I extended the free trial to 1 year in the mentioned timeframe of the AppAdvice campaign. Other customers where also able to start the 1 year trial and I tested it on my iPhone too. I would kindly ask you to consider changing your review. If you do so, please contact me using info@mkgames.org and I'm sure we'll find a good solution! ### 2/5 — Update bringt IAP! *2025-06-05* Die Beta User der ersten Stunde haben ihre Arbeit getan. Nun wird Geld kassiert… Finde die Praktik einfach nicht gut. Sry **Developer response:** Hey 👋🏻 hast du TestFlight genutzt am Anfang? Die App war seit der ersten Version mit kostenpflichtigen Inhalten versehen, soweit ich mich erinnere. Technisch ist es leider nicht umsetzbar, das Nutzer aus TestFlight In App Käufe auch innerhalb der AppStore Version erhalten. Du kannst mir einfach eine Email an info@mkgames.org schreiben und deinen Fall genauer beschreiben. Da findet sich sicher eine Lösung, ohne für einen Beta User „Geld zu kassieren“. ### 2/5 — iPad Pro 無法返回上一頁 *2025-01-26, version 3.5.3* iPad Pro 無法返回上一頁 ### 3/5 — Please fix *2025-05-01* I really like this app. I have two requests. First- I set up my sounds how I like it but the next day I open up the same one and though the selections are the same the sounds default back to the original version. Second- in the morning, even though I close out the app, when I get into the car the app plays. This morning I even had my audiobook app opened ready to play but this app though closed still was what played. Please fix this. The first is an annoyance when I am trying to go to sleep. The second is an annoyance when I am just waking up. This is a great app but the glitches are when I have the least patience. ### 3/5 — Back button doesn‘t work *2025-01-25* Great app, however the back button doesn‘t work and once starting a session, you have to close the app in order to try other sessions. Other than that an amazing app. **Developer response:** Thank you for reporting this. It should be fixed in the latest update 3.5.4. Let me know if it works better now. I’m always reachable using info@mkgames.org. Best Marvin ### 4/5 — Great start! *2025-01-10* I have several sleep apps. This app is new to me and seem to offer quality content. I am hoping the library grows. For some reason I need to mix up the material I listen to for it to work to help me sleep. Thanks for a good start. Looking forward to watching the content grow. **Developer response:** Hey there and thanks a lot for writing the review! If you have any additional feedback or problems, feel free to reach out to info@mkgames.org. - best Marvin PS: Do you saw the new handpan pieces I released with versipon 3.7? :) ## Most praised reviews (10 highest-rated) ### 5/5 — Wonderful *2026-03-20* This app is so nice to have, mostly when you are tired of listening the same music, when you take a shower, or when you have troubles sleeping. I strongly advice you to get it. ### 5/5 — Great app *2025-11-13* I use this with my rayban meta and it’s a great app to help focus **Developer response:** Thanks a lot for your review! Happy to hear you like the app. If you have any problems or ideas for new features, feel free to reach out at any time using info@mkgames.org. Best Marvin ### 5/5 — My autistic kid asks for it… *2025-07-14* …every night for sleeping time. The “3.0 Hz Starlight Dreams” is his go-to-sleep “digital sleeping pill”. High Quality audio, nice app. Recommended by experience. 👍🏼 ### 5/5 — Helpful *2025-07-05* ZenWave has helped me achieve a deeper level of deep sleep which is very beneficial ### 5/5 — Best App Ever *2025-06-18* I’ve tried many different apps for listening frequencies in my daily routine and this one is by far the best. They’re the first that allows me to select a frequency and mix it to other audios so I can put my favourite songs and still be hearing the frequency in the background. They’re always bringing new more settings of sessions. So maybe the future we can use frequencies above 40Hz (like 100Hz that has recently proven to help with motion sickness), that would be perfect. ### 5/5 — This is not from this world. *2025-05-07* This technology is scary. Use it daily and you will witness the power it has. Use it with caution. ### 5/5 — EL *2025-04-25, version 3.9.2* 😇 ### 5/5 — Only used a little so far *2025-04-25* Has a large selection and sounds good. Great background noise when focusing. ### 5/5 — Really well laid out. *2025-04-15* Very easy to enjoy. With excellent vibes. ### 5/5 — An outstanding app !!! *2025-03-30* This app is absolutely amazing, has a great variety of sounds, isochronic tones, binaural beats, different frequencies explained, for meditation, focus, sleep and relaxation, so everyone can find something to fit their needs or wants. Information guide is provided, so are tips for ease of use and to get the most out of app. ZenWave is so vast, I haven’t explored everything yet, but I am in awe to see and hear so many calming, relaxing or focusing sounds, and when you combine a beat with nature, soothing melody appears to lull you into easy, deep sleep in the beautiful zen garden, where one can hear and see tranquility. Many thanks to the developer for making this app free for a couple of days, and for his help, going that extra mile to fix a glitch on my phone.
