Add Background Music To Video

What it does

This is a mobile video editing tool designed for creating engaging slideshows and short videos, primarily for social media. Its core function is to make it simple to add and mix various audio layers, including a library of stock music, sound effects, and user-recorded voiceovers, to a sequence of photos or video clips.

Where it shines

The app excels in its streamlined, multi-layered audio editing interface. At 01:07, the timeline is clean and intuitive. The user can easily browse and add background music from a well-organized library (01:10), layer in specific sound effects like footsteps or crowd noises (02:17), and even record a voiceover directly onto a third track (02:59). This separation gives users impressive control over the final sound mix from a simple mobile interface.

UX highlights

Categorized Audio Libraries: Both music and sound effects are sorted into thematic categories like "Action," "Happy," and "Footsteps" (01:10, 02:18), which simplifies discovery and helps users find the right mood quickly.
Independent Track Controls: Each audio track (music, SFX, recording) can be selected independently on the timeline to adjust its volume or apply a fade effect (01:41), providing granular control that is often missing in simpler editors.
Simple Aspect Ratio Presets: The app offers one-tap presets for "Portrait," "Square," and "Landscape" formats (01:03), acknowledging that most content is destined for different social media platforms.
Direct Voiceover Recording: The ability to record audio directly into the editor (02:59) is a key feature for creators making tutorials, reactions, or narrated stories, removing the need for a separate recording app.
Clear Project Management: The home screen (04:09) displays saved projects as clear visual cards, with simple options to rename, duplicate, or delete via a three-dot menu, keeping the workspace organized.

Monetization & growth

The app uses a hard paywall triggered after the user's initial investment. The user selects their media first, and just as they expect to see the editor, they are presented with a subscription screen (00:30). This is a high-friction but potentially high-conversion strategy. It offers a 7-day free trial, framed upfront as a "Free Access" pop-up to prime the user. The paywall itself presents two main weekly and yearly plans: a single-app "Pro" version and a more expensive bundle that includes five other apps (00:33).

Who it’s for

This app is aimed at social media content creators, small business owners, and casual users who want to quickly produce videos with polished audio. Its simple interface is accessible for beginners, while the multi-track audio features provide enough depth for users creating short-form vlogs, promotional videos, or photo memories with narration and sound design.

Notes & opportunities

The post-investment paywall is an aggressive tactic that could alienate some users who expect to try the editor before committing. While likely effective, it could lead to negative reviews. Additionally, the process of adjusting audio volume (e.g., at 01:41) requires tapping the track to reveal a slider at the bottom. A more direct, on-timeline volume control like a draggable waveform could make this process even faster for users.
