- Hook Score for the first 3 seconds
- Viral view forecast before you post
- Heat map of drop-offs and replays
- Hooks, scripts, hashtags and ideas from one topic

How it works
The analysis happens before you post, which is the only time it can change anything.
Import a clip or paste a link
Pick a video from your camera roll, or paste a TikTok, Instagram Reels or YouTube Shorts link from the share sheet.
Read the three numbers
Hook Score for the opening, a view forecast for the clip, and a heat map that marks the seconds where viewers are likely to leave or replay.
Fix the dip, then post
Recut the opening, tighten the sag, add the hashtags and caption the app wrote, and post the version that scored higher.
What the app measures and writes
Three analyses of the video you have, and four generators for the one you have not made yet.
Hook Score
A 0 to 100 rating of the first three seconds: the window in which most viewers decide whether to keep watching or scroll.
How it works →Viral View Forecast
An estimate of the reach a clip can earn, read from the clip itself. Use it to compare two cuts of the same video before one of them goes live.
How it works →Engagement Heat Map
Second by second, where viewers are likely to leave and which moments get replayed, so the edit targets a specific dip rather than the whole video.
How it works →Hook Generator
Several opening lines for a topic, across curiosity, contrarian, result-first and other hook types, written to be recorded rather than admired.
How it works →Script Generator
A topic in, a ready-to-record short-form script out, with the hook, the setup, the payoff and the ending in the order the platforms reward.
How it works →Hashtag Finder
Tags balanced between reach and competition, so a video is not filed under a hashtag with eighty million posts and nothing else.
How it works →What makes a video go viral
Two lists: what a viewer responds to, and what the algorithm counts. The second list is how the first one gets measured.
What viewers respond to
A reason to keep watching that arrives before the third second
A payoff that is withheld long enough to matter and delivered before people leave
Something they want to send to one specific person
A sound or format they have seen this week, used with a twist
An ending that loops cleanly back to the start
What the algorithm counts
Average watch time as a share of the video length
Completion rate, and rewatches on top of it
Shares and saves, which weigh more than likes
Early engagement inside the first test batch
Comments, including replies you leave yourself
The app checks the first list before the algorithm checks the second
The Hook Score reads the opening, the heat map finds the sag, and the forecast tells you which of two cuts is more likely to get through the test batch.

Why Is My TikTok Not Getting Views?
A symptom-by-symptom diagnosis: zero views, stuck under 300, views without engagement, a sudden drop.

Questions creators ask before downloading
Can I go viral on TikTok with no followers?
Yes. TikTok scores each video on its own and shows it to a small test audience first, most of whom do not follow you. If that audience watches to the end and shares, the video is pushed to a larger one. Follower count decides who sees it first, not how far it can travel.
What is a Hook Score?
A Hook Score is a rating from 0 to 100 of the first three seconds of a video: whether the opening frame changes, whether a promise is made on screen or out loud, and how quickly the reason to keep watching arrives. It is a score of the opening, not of the whole video.
How accurate is the viral view forecast?
The forecast is an estimate built from what is inside the clip: the hook, the pacing and the likely retention curve. It cannot see when you post, whether the sound is trending that day or how your last ten videos performed, so use it to compare cuts of the same video rather than as a promise of reach.
Does Go Viral work for Instagram Reels and YouTube Shorts?
Yes. Import a clip from your camera roll or paste a TikTok, Reels or Shorts link. The analysis reads the video itself, so it does not matter which platform it came from or where you plan to post it.
Is Go Viral free?
The app is free to download and a subscription is required to use all features. Plans and prices are shown in the app and on the App Store listing, and a subscription is managed or cancelled from Subscriptions in your iPhone settings.
Why is my TikTok not getting views?
Most stuck videos fail the first test batch: the opening loses viewers before the third second, or the middle drags and completion drops. Zero views usually means the video is still processing or under review. The full diagnosis, symptom by symptom, is in the guide below.
