For mobile app marketers, AI UGC ads are a way to feed install campaigns a steady supply of new videos. An AI actor delivers a short hook about the app to camera, often cut next to a real screen recording. RiffAds can also start from a brief and one screenshot with its app review workflow, and it prices each ad before it runs. ### How it works 1. **Cast the actor**: Pick a library actor who looks like the people who use your app, or create one from a written description. 2. **Write the hook**: Paste a script that opens on the problem your app solves, or run the App review from a creator workflow with a short brief and one screenshot. 3. **Check the price**: The studio shows the credit cost before anything renders, so you can plan a batch of variants against your budget. 4. **Cut and upload**: Stitch the clip with your own screen recording, add captions, resize it for each placement and upload it to your ad platform yourself. ### Best for - App install campaigns - Feature launch ads - New country launches - Re-engagement ads - UA teams that brief an AI agent ### RiffAds in numbers - **74**: voice languages: write the script in a market's language and the actor speaks it with lip sync. - **848**: credits buy a 30 second talking actor ad with its voice, at $0.01 a credit. ### The numbers behind it - **10 to 30**: seconds is the length range Google suggests for App campaign videos, with portrait, landscape and square versions to reach more ad channels.

UGC ads for mobile apps are short, phone style videos where a person talks to camera about an app, often cut with screens from the app itself. AI UGC ads use an AI actor in place of a hired creator, so you can make many hooks for one app and test which ones bring installs. ### How long should an app install ad be? For Google App campaigns, aim for 10 to 30 seconds: that is the range Google's best practices guide suggests, in portrait, landscape and square. Other channels set their own limits, so check each one before you cut. In RiffAds, Seedance 2.5 Actor speaks for 4 to 30 seconds and OmniHuman 1.5 animates under 60 seconds of audio, so one talking actor clip can fill that range. The Stitch Videos tool joins clips when you need more. ### What aspect ratio should app install video ads use? Make a vertical 9:16 version first, then landscape and square when you can. TikTok recommends 9:16 for in-feed ads and also accepts 16:9 and 1:1, and Google suggests portrait, landscape and square App campaign videos to reach more channels. RiffAds makes actor frames in 9:16, 16:9 or 1:1, and its Resize tool reframes a finished clip with bars or a crop. ### How many UGC ad variants should an app test? There is no fixed number, but the platforms leave room for many. Google App campaigns take up to 20 video assets per ad group, and TikTok recommends 3 to 5 different creatives per ad group. With AI actors you can change the hook, the actor or the language for each version without booking a new shoot. ### How much does an AI UGC ad for an app cost to make? On RiffAds, a 30 second talking actor ad with its voice is about 848 credits, or $8.48 at $0.01 a credit. You see the price before each ad renders, and credits never expire, which suits testing in bursts. The Launch plan costs $49 a month. ### Can an AI actor say it uses my app? No, not as a statement of fact. The FTC's rule on fake reviews and testimonials bans testimonials that misrepresent that the speaker exists or used the product, and an AI actor never used your app. Script it as a presenter showing the app. When an ad could pass for real customers, the FTC Endorsement Guides say to disclose clearly that they are not, and TikTok requires its AIGC label or your own clear disclaimer on AI ads. ### Can an AI agent make app install ads for my UA team? Yes. API, MCP, Agent Skills and CLI are included on every plan, so an agent can draft hooks, price each ad and render it from your team's credit balance. The spend limits come from a person, not the agent: by default it may spend up to 600 credits on one job and 2,000 a day, and a workspace owner or admin can change both. You get the video file, and RiffAds never touches your ad accounts. ## About RiffAds RiffAds makes realistic UGC video ads with AI actors, lip-synced to your script, in the studio or from your AI agent through API, MCP, Agent Skills and CLI.
