A utility application for iPhone and iPad that increases the volume of quiet videos and audio files. Users import media from Photos or Files, set the boost level with a percentage and dB slider, preview the result with a live level meter, and save a boosted copy while the original stays unchanged. A built-in soft limiter and an optional Bass Boost control help keep boosted sound clear and full.
- Launch Meta Ads and TikTok Ads targeting video editors and lecture or voice note users to add a paid acquisition channel. - Optimize the paywall and pricing tiers in A/B tests to raise the install-to-paid conversion rate for Premium boost levels. - Expand ASO keywords and paid campaigns in Tier-1 markets such as Germany and the Netherlands, where the app already supports the language.
