An app promo video sells downloads by showing the app solving a problem, not by listing features. Indie devs are underserved here: app store screenshots are static and most promo videos are landscape demos, but a vertical reel that opens on a relatable problem and shows the app as the fix converts far better in a mobile feed.

The structure is hook problem, the app, key feature, download CTA. Open on the frustration the user has, introduce the app as the answer, show the single most impressive feature in action (not all of them), and make downloading frictionless. One killer feature beats a feature dump every time.

Reelry turns your feature list into that promo structure and produces the finished vertical video, with script, visuals, voiceover, and captions. You supply the app; the tool builds the promo.

## How to make one with Reelry

1. Enter your app above. Add the killer feature to get the outline.
2. Generate the reel. Paste the outline into Reelry; AI writes the script, builds the scenes, records voiceover, and adds captions.
3. Add a screen recording. Drop in a clip of the app in action where you want it, then export the 1080x1920 MP4.

## Who it is for

Indie app developers, SaaS and mobile startups, and product marketers who need vertical app promos without an agency.

## FAQ

**Why a vertical app promo instead of a landscape demo?**

Because the install decision happens in a mobile, vertical, scrolling feed. A vertical reel that opens on a relatable problem and shows the app as the fix converts far better there than a landscape demo or static screenshots. The outline this tool builds is structured for that feed.

**Should I show every feature?**

No. One killer feature, demonstrated clearly, beats a feature dump. Viewers download for the one thing that solves their problem, not a list. The outline this tool builds focuses on a single standout feature plus proof.

**Is the app promo video maker free?**

The outline builder is free with no signup, and Reelry has a free plan to produce the finished video.
