We’ll take it into consideration and work on improving it in future updates. ### 1/5 — Bad app *2026-05-11* If you have to pay to use the booster at full capacity, it’s not a good decision to get this app. Android users don’t have to pay to use this app. IOS does. Math isn’t mathing. **Developer response:** Thank you for your feedback. The app requires a paid plan to help support the development team, allowing us to continue updating features, fixing bugs, and improving the overall quality of the service. ### 1/5 — no spotify *2026-05-09* can’t use spotify **Developer response:** Sorry for the inconvenience. Due to operating system limitations, third-party apps cannot directly boost system volume or modify Spotify audio. Our app provides audio enhancement features within allowed limits. Thank you for your feedback and understanding. ### 5/5 — Bumbaclot *2026-05-09* Amazing **Developer response:** Thanks for the 5 stars! We’re glad you’re enjoying the sound experience --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
