iface: Face Swap & Deep Fake

What it does

iface is an AI-powered video creation tool that allows users to seamlessly swap their face onto a wide variety of video clips. The app provides a large library of templates from movies, music videos, and pop culture, enabling users to create humorous and shareable deepfake-style content. It also offers a premium feature to swap faces onto any video from the user's device or via a YouTube link.

Where it shines

The app excels at getting users to a valuable result quickly. The onboarding is minimal, pushing the user to select a photo and start their first creation within seconds of opening the app (00:13). The loading process, while long, is a standout moment of UX design. It uses dynamic text to manage user expectations, even acknowledging when it's "taking longer than usual" (00:43), which builds trust. The sheer breadth of the template library (03:30) provides strong long-term engagement potential, encouraging repeat use.

UX highlights

Contextual Instructions: Instead of a generic tutorial, the app overlays clear guidelines like "No bangs" and "Face centered" directly onto the user's selected photo (00:14).
Feedback-Driven Growth: The app asks for an in-app rating on the result (01:11) before triggering the official App Store review prompt, a smart way to filter for positive reviews.
Clear Video Trimming: For custom videos, the trimming interface is simple and intuitive, with clear handles and a preview (02:04), making it easy to select the perfect clip.
Flexible Import Options: The ability to import videos directly from YouTube (01:47) is a powerful feature that greatly expands the creative possibilities beyond the app's own library.

Monetization & growth

iface employs a freemium model with a soft paywall. The first creation using a template is free, demonstrating the app's value. After this, a paywall appears at 01:22, offering yearly and monthly subscriptions to unlock more features. Premium functionality, like using your own videos, is strictly gated behind a hard paywall (02:13). The app uses an interesting tactic where abandoning this paywall triggers a special, timed 50% discount offer (02:20) to recapture hesitant users.

Who it’s for

This app is primarily for social media users and meme creators looking to generate funny, personalized, and shareable video content. It appeals to a younger demographic active on platforms like TikTok and Instagram. The ease of use also makes it accessible to anyone curious about AI and deepfake technology who wants to experiment without needing technical skills.

Notes & opportunities

The core friction point is the long and variable processing time for video generation. While the app does a good job managing expectations, this wait could still lead to user drop-off. An opportunity exists to introduce a notification system or a video queue, allowing users to start multiple creations and be alerted when they are ready. This would reduce perceived wait time and encourage more extensive use of the app in a single session.
