For a fitness app, a strong video should drive more than an install. It should lead to a first plan, completed workout or trial start. AI UGC makes it faster to test motivations such as limited time, home workouts, progress and personalization.
A simple test matrix
- one pain point per video;
- two opening hooks in the first seconds;
- one CTA for install or trial;
- activation and purchase as the primary outcomes.
Do not promise medical outcomes or use fake before-and-after stories. Separate creative tests from store-page tests so the team knows what changed CAC.
CrystalCore produces AI UGC variations for Meta and TikTok and connects them to install and activation measurement through AI UGC Ads and Marketing Analytics.
