It just can’t manage any sort of frame rate to run a 4K video, and really needs to be improved. Hard to recommend at this stage ### 4/5 — Molt bonica i relaxan *2025-03-09, version 2.012* És molt tranquilitzant i entretinguda. Perfecte per relaxar-se ### 5/5 — AQUARIUM 4K square Root symbol *2025-02-09, version 2.012* Miqqey Maosê ### 1/5 — No funciona *2025-01-27, version 1.00* NO funciona en IMAC ### 1/5 — Nao Funciona *2025-01-17* App nao funciona fraude ### 1/5 — Stopped working *2025-01-15, version 2.012* This app was great for about a week on my Apple TV. Now it doesn’t work, screen black and spinning. ### 1/5 — Аквариум *2025-01-11* Не работает на ios12 хотя написано что будет работать на iOS 11 За что заплатил деньги? ### 1/5 — No la compren *2024-09-07, version 2.012* RATEROS NI FUNCIONA ### 4/5 — Eigentlich ganz gut *2024-07-20* Zu erst war der Inhalt anscheinend noch nicht geladen, so dass die App am ersten Tag noch nicht nutzbar war. Aber jetzt wo alles geladen ist, ist die Auswahl echt schön. ### 1/5 — Does not work *2024-07-13, version 2.012* €1 flushed in the aquarium toilet ## Most critical reviews (10 lowest-rated) ### 1/5 — Waste of money!!! *2026-02-08, version 1.00* Just paid for this app as part of a bundle that cost me $12-99AUS. According to the app store it should be compatible with my desktop Mac but it doesn’t work. The so-called screensaver is just a plain black screen. There are options at the bottom but you can’t click on any of them and there is no option for in-app purchases. I want a refund but Apple tells me I’m somehow not eligible. ### 1/5 — 작동하지 않습니다. *2026-01-24, version 1.00* 작동하지 않습니다. ### 1/5 — Do not buy! *2026-01-18, version 3.03* Does not work, do not buy and be scammed ### 1/5 — Crashes *2026-01-17, version 3.03* Crashes shortly after booting TVos 26.2 ### 1/5 — NON FUNZIONA *2026-01-06, version 1.00* L'APP NON FUNZIONA ### 1/5 — Do not buy *2025-09-27, version 1.00* Does not work on any advertise platform. Id give it zero stars if possible. ### 1/5 — App vorhanden, Aquarium lädt aber nicht. *2025-09-25* Ich bewerte vor selten eine App, aber diese App ist mit Abstand, die schlechteste, die ich überhaupt gesehen habe. Die 0,99 € kann sich jeder sparen. Die App lädt zwar auf das Apple TV beziehungsweise lässt sich installieren, aber nicht ein einziges Aquarium funktioniert. Es dreht sich immer ein Kreisel, nix passiert. ### 1/5 — Arnaque *2025-09-25* Écran noir juste des flocons de neige ou des gouttes de pluie ### 1/5 — Keine Wiedergabe *2025-05-04, version 2.012* Die Videos laden bei mir gar nicht und werden dementsprechend nicht abgespielt. ### 1/5 — Ni acuario ni chimenea *2025-02-03, version 2.012* Es un engaño en TV no carga en el móvil _> y tampoco asistencia nula !! En el Store ## Most praised reviews (10 highest-rated) ### 5/5 — Great app *2026-03-04, version 3.03* Love this app. So many different videos. ### 5/5 — Enjoy the Peace *2026-01-24, version 3.03* I love this app The views and sounds of the sea appear as a large fishbowl without the trouble of clearing and caring required with a fish tank. It feels like a deep sea dive from the comfort of your own home. I I’ve the sounds of nature, the many plants and creatures of the see. It’s absolutely breathtaking… ### 5/5 — Buena *2026-01-19, version 3.03* Me gusta ### 5/5 — Best app ever!!!!!!!!!!!!!!! *2026-01-10, version 3.03* The music is very relaxing ### 5/5 — Best app ever!!!!!!!!!!!!!!! *2025-12-02* The music is very relaxing ### 5/5 — Super 4,K Auflösung *2025-11-15* Super App Software ### 5/5 — En el iPad funciona muy bien *2025-10-30, version 1.00* Tenéis que actualizar para solucionar problemas de que en el iMac no funciona.
