Can’t cancel trial time
Response from developer
Thank you for your feedback. Trials and subscriptions are managed by Apple, so you can cancel anytime in Settings > [your name] > Subscriptions, at least 24 hours before the trial ends. The app works on iPhone 17 Pro with iOS 27; if something isn't working as expected, please contact us through the app and we'll be glad to help.

Thank you for the kind rating! We are glad Volume Booster works well for you.
Can’t use with streaming ?
Response from developer
Thanks for writing. On iOS 27, Volume Booster can now boost the sound of other apps, including streaming services. Update to the latest version, open the all-apps boost screen and follow the short steps there to turn it on.
FAKE
Response from developer
Thank you for taking the time to share your feedback. Volume Booster enhances the audio of your own music and media files through its equalizer and bass boost; it does not change system, call or notification volume, and we never claim otherwise. If a specific feature didn't work as expected on your device, please reach out through the support link in the app and we'll gladly help.
