Before/after ads for apps: the glow-up format, for marketers

The before/after glow-up slideshow is not just creator content. It is one of the cheapest UGC-style ad formats a B2C app can run. It maps to a clear with-and-without story, it ships as photos instead of video, and it lands in Photo Mode where carousels beat video on saves and comments. If you market an app and you are not testing it, you are leaving the easiest format on the table. The mechanics are the same as the organic version in how to make a before/after glow-up slideshow, pointed at your product.

Why the format fits apps so well

Every B2C app is a transformation: messy to organized, anxious to calm, alone to matched, broke to saving. That is a before and an after. The slideshow format hands you a frame for it that viewers already understand, so you spend your effort on the offer, not on teaching people how to watch.

Because it is a photo post, it is cheap to make at volume. You can ship ten angles in the time a single talking-head video takes, which is exactly what creative testing needs.

The 3-slide ad structure

Slide 1: the problem (the before)

Show the exact pain your app removes, as a real-looking phone photo. Dating app: lonely on a Friday night. Budgeting app: an overdrawn balance. Add one line of on-screen text that names the feeling.

Slide 2: the after

The same person, visibly better, living the outcome your app delivers. Keep the face and setting continuous so it reads as one story.

Slide 3: the app hint (the closer)

A fake lockscreenwith a notification from your app is the strongest closer. It implies the app caused the turn and pushes the comment “what app is that?”

How to produce it without creators

You do not need a UGC creator or a camera. In the Hookslides studioyou generate the before and after with the same face locked across both, drop in the free lockscreen closer, and export each slide at 1080×1920. That is the whole pipeline, and it is how faceless operators run the format daily, covered in faceless TikTok content with AI.

Where this beats AI video tools

Most AI ad tools only make spokesperson video. A tool like Arcads renders a talking head from a script and cannot produce a static carousel or a fake-screenshot slide at all, and Creatify is video-first too. For the slideshow format you would need a separate tool, which is the gap Hookslides fills. See the full breakdown on the Arcads alternative page.

Stay compliant

These photos are dramatized illustrations, not real customers, so keep your claims truthful and follow the AI-disclosure rules for your market. Hookslides bakes an “AI-generated” label onto the AI slides by default, so the disclosure ships with the creative instead of being an afterthought.
