How it works

The analysis happens before you post, which is the only time it can change anything.

STEP 01

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.

STEP 02

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.

STEP 03

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 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.

Analyze my video

Four habits of videos that get through

None of these need a big account. All of them show up in the heat map.

Win the first three seconds

Open on the result, the question or the contradiction. Titles, logos and "hey guys" cost you the viewers who decide fastest.

Cut for completion, not length

A twenty-second video most people finish beats a sixty-second one most people abandon. Trim the setup until the payoff arrives early.

Use a sound while it is rising

A trending audio helps most in the first day or two of its rise. Late is fine for a joke; it is not a distribution strategy.

Three to five hashtags, tiered

One broad tag, one or two for the category, one or two for the niche. Ten tags do not add reach; they blur what the video is about.

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.
