Before you post
Will my TikTok go viral?
Nobody can promise that a video will go viral. What you can do is check the things that decide how far it travels before you post it, while a fix still counts. This page gives you a five-point check you can run in a couple of minutes, and shows how Viral IQ, an AI video analyzer for iPhone, does the same check and scores the video.
The short answer
TikTok first shows a new video to a small group of people. If they watch it to the end, rewatch it, comment or share it, TikTok shows it to more people. If they swipe away in the first seconds, it stops there. So the more useful question is where people will stop watching, and whether you can fix that before you post.
The 5-point check
- The first 3 seconds. Is something happening on screen right away? Would a stranger know why they should keep watching? Greetings, logos and slow pans lose people here.
- Pacing. Cut pauses, repeated sentences and anything that does not move the video forward. A slow middle is the most common reason people leave halfway.
- Payoff. If the opening promises something, deliver it early enough. A late payoff loses the viewers you worked to hook.
- Text and sound. Many people watch on mute, so put the key line on screen. Check that your voice is clear over the music.
- The ending. End on a line that loops back to the start, or give people a reason to comment, save or send it to someone.
How Viral IQ checks it
Upload the finished video from your camera roll. Viral IQ watches the whole clip, including the picture, sound and on-screen text, and gives you:
- a viral score from 0 to 100 and a separate hook score for the opening seconds
- predicted retention at 25%, 50%, 75% and the end of the video, plus average watch time
- predicted like, comment, save and share rates, rewatchability and scroll-away risk
- feedback on the hook, pacing, call to action, audio, visuals, on-screen text, trend fit and platform fit
- a suggested title and 3 to 5 hashtags for that video
Fix the weakest part, run the new version, and post the one that scores higher.

Questions
Can an app tell if my TikTok will go viral?
No app can guarantee it. An AI analyzer like Viral IQ estimates a video's potential from the video itself and points to what to fix before you post.
When should I check my video?
After editing and before posting. Once a video is live, changes no longer help that post.
Does it work for Reels and YouTube Shorts too?
Yes. You pick your main platform (TikTok, Instagram Reels or YouTube Shorts) and the feedback is written for it.
Do I need to connect my TikTok account?
No. You upload the video file from your iPhone. There is no sign-up and no social login.
