However, I have a problem with apps listed as…”Free” that aren’t actually free. What’s the point in lying about the price? I know the play store doesn’t price monthly/weekly/daily prices, but at least let me know when I go to the reviews. Cause now I’m here, doing just that. I won’t say the price, but it’s not terrible, below 20 per month. ### 4/5 — Awesome except one little thing *2025-02-04, version 11.3.3* Spend hours lost in this but PLEASE sort out the UI overlay. I can’t click record or settings manually to adjust a parameter it can’t be done without it triggering the ‘flow’ onscreen. Very annoying when I want to start from static images or whatever. ### 4/5 — ??? *2024-11-15, version 11.2.8* I have already purchased this app. It somehow got deleted from my phone & I have reinstalled it. Why not it let me restore my purchase??? ### 4/5 — can't record the video when swiching presets *2024-10-25, version 8.7* can't record the video when swiching presets ### 4/5 — Sehr gut und schön – hier sind ein paar Verbesserungsvorschläge *2024-07-30, version 11.2.3* Es ist ein sehr gutes und schönes Spiel, aber bitte die Auswahl an vorgegebenen Presets noch erweitern. Das Suchen nach einem bestimmten Preset ist mühsam. Eine große Ansicht, in der alle Presets alphabetisch aufgelistet sind, wäre sehr hilfreich. ### 4/5 — Good app when it doesn’t glitch *2024-06-10, version 10.0.0* This is a good app however, I have had it glitch to the point where I can’t event start it so I have to delete and re-install. Sometimes this doesn’t even work. ### 4/5 — Soooo calming *2024-05-11, version 10.0.0* I love this app so much and there is like no ads compared to other games . Also when I am upset it calms me down so easily and is so relaxing it is great and very satisfying . You have to pay to unlock everything yet just the free stuff gives you so much you like don’t need it anyway . I highly suggest this game ### 4/5 — Awesome *2024-04-28, version 9.0.1* It’s serene and awesome need more music though ### 4/5 — Relaxing *2024-04-16, version 9.0.1* Like it alot but I’d like to be able to turn to music off. ### 5/5 — Rubbish and garbage game *2024-03-29, version 9.0.1* I hate this game because whenever I try to open the game it crashes 😭😭😭😡😡😡 ### 5/5 — Great game so satisfying *2024-03-22, version 9.0.1* I love this game it made me wanna cry because I’ve been searching for games like this I was on a mission and then I found it I just love it so much you should get this game ### 5/5 — Great *2024-03-15, version 9.0* Very calming and satisfying. Peaceful ### 5/5 — ❤️ It! Beautiful & Mesmerizing! *2024-03-04, version 9.0* Love the flowing fractal-style colors (can tweak many settings) to aid in relaxation. Also tried the music visualizer, although I'm not really sure it moves in sync with the music. Thanks for this wonderful app and updates! ### 5/5 — I only vote on really good apps this is REALLY GOOD!!!!!!!!! *2024-02-20, version 9.0* Basically, this app is sooooooooooooooooooo relaxing and calm and it makes me feel amazing and helps me destress. I have a veeeryy stressful life because I am in high school and this is my go-to app when I need something to help me calm down. ### 5/5 — I have no words *2023-12-04, version 8.6* No ads Just straight into the beautiful lights I highly reccomend this ## Most critical reviews (10 lowest-rated) ### 1/5 — Plays sound even when volume down *2025-01-03, version 11.2.9* I don’t know why or how but it plays loud music even with my volume down and phone on silent. I can’t open the app because it will wake someone up. Awful design. ### 1/5 — Sorry *2024-05-15, version 10.0.0* I’m sorry but It stresses me more nothing can calm me I’m so very sorry about this ### 1/5 — 전화가 오네요 *2023-07-04, version 8.3.1* 자동차랑 블루투스가 연결되어 있는 상태에서, 이 앱을 실행하면, 자동으로 “나에게” 전화가 걸립니다. 왜죠???? ### 1/5 — Malware alert *2022-12-09, version 6.2* Downloaded this app and it then wanted me to download Rosetta so it can be played on my Macbook Air. Did so and received a malware alert relating to two files (ReceiverHelper and ServiceRecords) and recommended deleting these files, which I have done. Report sent to Apple. ### 1/5 — App stopped working! *2022-02-17, version 5.6* Just bought the app a few days ago, and now it won’t even open! I need support to get back to me ASAP! Very disappointed. ### 2/5 — It dose not let me do the fluid on my own 😡😡😡 *2024-08-09, version 11.2.3* When I try to do it on my own it distracts me and I just want it do let me try and it Dose not let me have turn 2stars ### 2/5 — Za cicho *2022-12-29, version 7.2.4* Mam ustawione głośność na maxa, a dźwięk jest bardzo cichy. Wizualnie aplikacja fajna, ale dźwięk jest ewidentnie za cichy. ### 2/5 — App crashes *2022-01-01, version 5.5* I liked this app when it worked, but now every time i open ut, it almost immediately crashes. ### 3/5 — It’s ok but… *2024-08-30, version 11.2.5* It’s really good and calming but there’s a lot of stuff that I can’t get because it has to be paid it would be awesome if I had it but I don’t other than that it is pretty much a super cool app 🤩 ### 3/5 — Great but needs more organization *2023-12-04, version 8.6* Maybe a little more explanation on what each effect does. I paid the premium lifetime and my music still gets stopped every time i open the app unless i force it to play through a different device, that’s a stupid feature. I understand for non-paying it would make sense to limit that capability, but not for premium users, I don’t have all my music downloaded in iTunes and shouldn’t be forced to play music through the app just to play with some water effects while I relax. ## Most praised reviews (10 highest-rated) ### 5/5 — Finally *2026-06-12, version 11.4.2* This app works and doesn’t seem to want a subscription. Main reason for 5 star is that it reacts to my music player (Plexamp). Takes a little adjusting to get it reactive but can’t wait to “use” this app if you smell what I’m stepping in. ### 5/5 — Game Changer! *2026-02-13, version 11.4.2* I’d been making music videos by screen recording on my MacBook for almost ten years when it finally stopped working. I’m on the SPECTRUM and it’s difficult for me to sit still and hear music unless I’m driving. In 2016 i became a recluse after some trauma and stopped leaving my apartment. Not listening to music started to amplify my symptoms and I was practically catatonic until I started watching my music through a visualizer. Almost immediately I realized that if it helped me it could help others so I started screen recording while I watched, and uploading them to YouTube. After a few years however my laptop and the software I was using became practically obsolete. So I stopped. For two years I really struggled emotionally because I wasn’t getting music in me. I love good music and need it. About a month ago I found this app. I’ve since produced over 100 new music videos and shared them… and I can’t stop. This product is the best investment I’ve made in well over a decade. With a phone more powerful than the laptop ever was, and the Fluids app, I’m having a great time; and feel better than I have since before I can remember. Highly recommended. Buy it. ### 5/5 — Can you add an Deku izuku midorya from my hero academia fluid pls it’s Green electricy *2026-01-16, version 11.4.2* Pls ### 5/5 — Gut aber Zu teuer *2025-07-16, version 11.4.1* Ich finde es eine super Entspannungs App aber Ich finde auch dass die freischaltung für 50 € viel zu teuer ist . Vielleicht könnten sie das berücksichtigen Lg ### 5/5 — NO WALLPAPER?!? *2025-03-20, version 11.3.3* Why can’t I set it as a wallpaper?this app is great but not being able to set it as a wallpaper in infuriating ### 5/5 — Fluids, it flows like i want it! *2025-01-25, version 11.2.9* I use this Shades graphics processor with NDI in- and output for VJing in combination with resolume AVENUE. The signal is immediately recognized in the network and transmitted without interference. Audio signals can also be tapped as pulse generators via NDI. A particularly practical addition at this low price! During live performances, this app shows its strength with its targeted and logical menu navigation. I am pleased with the stability and performance of the processor. Any questions about the app are dealt with promptly and competently. Suggestions are also gladly accepted and implemented as quickly as possible. - Unfortunately, this is no longer a matter of course these days, but it is essential for professional work! As FLUIDS pro meets ambitions and private requirements, guests not only make big eyes with the support of this app at small party events with an LED video wall, but also visibly enjoy the video performance. All in one: great app with A-Grade graphics! Oh... on my wishlist are three items too: BMP, Loops and ableton LINK sync. Thanks to the MARVIN KRÜGER team for FLUIDS. ### 5/5 — It’s so satisfying *2024-12-08, version 11.2.9* I have this game. ### 5/5 — Fluids *2024-07-18, version 11.1.2* Perfekt!!! ### 5/5 — I love it! It calms me down *2024-04-22, version 9.0.1* There’s no adverts! Which I really love about this game and it’s not like the others where you watch billions of adverts and sign subscriptions to play. But this one is a one in a billion! It’s beautiful I love it I use it every day when I get into fights it calms me down so much 10/10 ### 5/5 — Audio visualizer problems *2024-03-30, version 9.0.1* I really like the audio visualizer, it seems like an added bonus on top of what I was actually looking for, but the issue with it is that the audio quality is pretty bad for some reason. Not sure what the source of the issue is, but this is the only app I have where the mp3 quality takes a nose dive --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
