Key takeaways

The hook is the first one to two seconds and decides whether anyone sees the rest.
Five hook families work for apps: problem, curiosity, result, authority and direct.
Specific, audience-named hooks beat vague ones; the visual should move in the first two seconds.
Test hooks by changing only the opening line and comparing average watch time.

Your hook is the most important part of a short-form ad. Everything after it only matters if people stay. Below are 25 reliable hook formulas for app ads, with examples you can adapt. Replace the bracketed parts, or use the free TikTok hook generator to fill them in automatically.

Problem hooks

The pain point: "[Painful thing] is costing you [loss]."
The stop-doing: "Stop [common habit] if you want [outcome]."
The rhetorical question: "Why is [task] still this hard?"
The relatable moment: "That feeling when [relatable situation]."
The warning: "Do not [action] until you see this."

Curiosity hooks

The secret: "Nobody tells [audience] about this feature."
The open loop: "I found the setting that fixes [problem]."
The reveal: "This app does something I did not think was possible."
The unexpected: "I was wrong about [category] apps."
The teaser: "Wait for what it does at the end."

Result hooks

The number: "I [achieved result] in [short time]."
The before and after: "[Before state] to [after state] in [number] taps."
The speedrun: "[Task] in 15 seconds."
The saving: "How I saved [time or money] every [period]."
The proof: "This is what [metric] looks like after one week."

The recommendation: "If you are a [audience], download this."
The insider: "Here is what [professionals] actually use."
The comparison: "[Old way] vs [app] and it is not close."
The list: "Three apps every [audience] needs."
The comment reply: "Replying to a comment: yes, there is an app for that."

Direct hooks

The call-out: "[Audience], this is for you."
The challenge: "Try this for 7 days."
The tutorial: "How to [outcome] in three steps."
The myth buster: "You do not need [expensive thing] to [outcome]."
The confession: "I wasted [time or money] before I found this."

What makes a hook work

Specific beats vague. "Cut invoicing from an hour to two minutes" beats "save time."
Audience named. Naming who it is for filters in the right viewers.
Visual motion. Pair the line with the app screen or a gesture, not a static frame.
Matches the video. A hook that over-promises loses viewers by second five.

How to test hooks properly

Change one variable at a time. Post at least five variants of the same body, track average watch time and completion, then double down on the top two formulas. Otto bakes this in: each piece in a batch uses a different hook format and recent hooks are tracked so they do not repeat.
