40 reaction hook ideas for app ads, sorted by niche

A good reaction hook is an emotion, a setting and one line of text. Below are forty combinations we'd test first, grouped by app category. Each one is written as reaction → caption, so you can search for the clip and paste the line.

If you're new to the format, start with what a reaction hook is and how to build the ad.

2. Shocked looking at phone in the gym → "wait, my form was THAT bad?"
3. Proud flex in the mirror → "3 months of following an app. that's it."
4. Skeptical face, then nodding → "I didn't think a 12-minute workout would work"
5. Lying on the floor, exhausted, thumbs up → "day 1 of letting an app coach me"

FAQ

How many hooks should I test per ad?+

Start with 3–5 hooks on the same body. The hook decides most of the outcome, so testing hooks is cheaper than testing whole new ads.

Should the reaction match the app's niche?+

The setting should. A gym reaction for a fitness app or a kitchen reaction for a meal app feels native. The emotion itself can cross niches.
