No descarguen esta app, muy mal gestionada. ### 1/5 — WORST APP EVER *2024-06-03, version 2.0.0* This app is so bad it won’t let me get on of the first page of it. It is horrible and ridiculous I just wasted all of my time getting a STUPID APP!!!!! I’m just so mad right now🤬🤬🤬🤬 ### 4/5 — Thank you ❤ 🐶🐨🐵 *2024-05-29, version 1.3.5* O ### 1/5 — 0 star!!!!!!:| *2024-05-24, version 1.3.5* Have to pay and doesn’t work ### 3/5 — I mean it’s alright *2024-05-22, version 1.3.5* So when you open the app it wants to charge you $20 a month fee to use the app but that’s easily avoidable and I’m not sure yet but I think you only get one charging wallpaper you get like a car moving like driving down the road it’s pretty cool with the lights and everything but I’m pretty sure that’s the only one you get and you have to have the app open when you’re charging your phone ### 1/5 — 0 *2024-05-20, version 1.3.5* 真的0 ### 1/5 — Not working and requesting subscription all the time *2024-05-04, version 1.3.5* Useless app. ### 1/5 — Scam *2024-05-02, version 1.3.5* If you gonna advertise it and not say you have you to pay is annoying and you use it for money so you can get downloads to get paid ### 1/5 — Nicht Empfehlenswert *2024-05-02* Is halt nich gut, funktioniert nich gut man muss Geld bezahlen und man hört keinen Ton während man die App benutzt. ~Fut ### 2/5 — review *2024-05-01, version 1.3.5* if you cant be bothered to spend money then there is no point in downloading it ## Most critical reviews (10 lowest-rated) ### 1/5 — 광고 어떻게 봄?? *2025-08-29* 또 단축어 계인용 게이블이 뭐임?? ### 1/5 — Waste *2025-06-21, version 2.0.2* Don’t bother!! The second it finishes loading a subscription window pops up. And it’s freakin expensive for what it is. These developers are delusional or have super inflated egos to think this it worth $24 a month! Nahahahah ### 1/5 — Dookie *2025-03-12, version 2.0.2* Yes it only works In the app Yes you need to pay a ridiculous subscription fee Yes it’s not worth it. Delete ### 1/5 — DESTROYS MY DEVICE *2025-02-04* I usually don’t make reviews but hi. So I opened the app cuz I found it on the App Store, right? And when I saw it, it looked cool. So, I opened the app and used it. It did not work. Ignore the good reviews. Next thing you know, it wants you to pay a scam $20 a month (Which isn’t even worth it) but it may not seem like much but it all adds up to something, It made my iPad glitchy and broken as it felt corrupted. It broke my iPad and I forgot most of it but DO NOT GET! It literally made my iPad corrupt. ### 1/5 — Subscription won’t cancel *2025-01-16, version 2.0.1* I’ve been trying to cancel this for months and keep getting charged weekly anyway ### 1/5 — Pas fiable *2024-09-30, version 2.0.1* Cette application n’est pas fiable et vous vole vos donnés sans constamment . ### 1/5 — My life story *2024-07-20, version 2.0.0* I found this garbage due to ads that kept pestering me while I was playing some weird bootleggy Amanda the adventurer subway surfers game. 10,000,000/10 changed my life ### 1/5 — SCAM *2024-07-20, version 2.0.0* This whole app is a SCAM! Let me tell you, ads always make the app look cool but when you download the app it makes you pay money. I do not recommend this product. I looked at the app for 2 minutes, and I deleted it. 1/5 stars ### 1/5 — Mon avis *2024-07-04, version 2.0.0* Je suis déçu l’application n’est même pas gratuite il faut payer pour les fonds d’écran 😐😔☹️ ### 1/5 — Terrible. *2024-07-02, version 2.0.0* It cost money to even get a wallpaper. I see that and I instantly deleted this app. Not even a few free wallpapers? 19.99 to even use this app is very expensive for wallpapers. ## Most praised reviews (10 highest-rated) ### 5/5 — 👍🏻 *2026-07-07, version 2.0.2* 👍🏻 ### 5/5 — Excellent *2026-02-15, version 2.0.2* I love the app ### 5/5 — 𝕀𝕥'𝕤 𝕘𝕠𝕠𝕕!!!
