Equalizer+ HD music player

What it does

Equalizer+ is a mobile music player designed for users who want granular control over their audio experience. The app allows you to import your own music files from various sources, including local storage and cloud services like iCloud and Google Drive. Its core feature set revolves around powerful audio customization tools, including a multi-band equalizer, a bass booster, and audio visualizers.

Where it shines

The app excels in its direct and transparent onboarding. A standout moment is the 'Free Trial Timeline' screen (00:15), which clearly explains the trial process before asking for a commitment. This builds significant user trust. Once inside the app, the main player screen shines by making its powerful tools highly accessible. The control bar at the bottom (01:45) provides immediate access to the bass booster, equalizer, and visualizer without needing to dig through menus.

UX highlights

Simple Import Flow: The process of adding music is straightforward. The app offers clear source options (01:00) and confirms successful downloads with a clear dialog (01:08).
Integrated Player Controls: Core features like the equalizer and bass booster are integrated directly into the player UI, allowing for real-time audio adjustments while listening.
Helpful Onboarding Pop-up: A small, contextual pop-up (01:17) orients the user to the music queue feature as soon as they start playing a track for the first time.
Easy Playlist Management: Creating a new playlist and adding a track to it is accomplished in just a few taps directly from the player options (01:36).
Clean Visual Feedback: The visualizer (02:07) provides an engaging and responsive animation that syncs with the music, enhancing the listening experience.
Smart Rating Prompt: The app uses an emoji-based sentiment check (03:48) before asking for an App Store review, effectively filtering for happy users.

Monetization & growth

Equalizer+ employs an upfront monetization strategy. After a brief feature showcase, it presents a soft paywall with a 3-day free trial for its single monthly subscription plan (00:20). This gates the entire app, ensuring every user encounters the offer. For growth, the app implements a well-timed feedback loop. After a period of use, it asks for an internal rating and funnels users who provide positive feedback directly to an App Store rating prompt (03:54), a tactic designed to improve its public rating and visibility.

Who it’s for

This app is ideal for audiophiles and music lovers who maintain their own library of digital music files rather than relying on streaming services. It caters to users who want to fine-tune the sound of their music, whether it's boosting the bass for a workout or adjusting EQ presets for different genres. It's for the listener who values customization and control over their audio.

Notes & opportunities

While generally polished, there are a few areas for improvement. The empty states, such as the initial 'No tracks' screen (00:46), are quite barren and could benefit from more guidance or a more engaging design. Additionally, the search function appears to have limitations. At 03:38, searching for 'heaven' yields no results, even though a track with that title is currently playing, suggesting the search may not be indexing the library correctly.
