A tool that matches outlier TikTok videos to App Store ranking jumps to find converting formats.
Spytok matches outlier TikTok videos to App Store ranking jumps, often across several countries at once, which signals organic reach. It scans hundreds of thousands of videos and surfaced a 106x outlier in fitness. Lesson: judge formats by rank movement, not views (16M views barely moved Menace), and validate a format before building.
From Yannis on Spytok
Judge a format by App Store rank movement, not by views. Spytok lines up the dates of viral outlier videos with an app's ranking jumps. A 16 million view post for Menace barely moved its rankings, while some 1 million view posts lift an app into the top 100.
Yannis's own scratch map app got millions of views from a post-breakup text and no installs. Another case got 7 million views and no rank better than 170. The strongest signal is a repeat: one post lifts the ranks, then a later post in the same format lifts them again.
Rank jumps in several countries at once point to organic reach. When a viral video lines up with ranking jumps across multiple countries at the same time, Yannis reads it as organic traffic rather than paid ads.
Look for posts far above the account's own median views. A post that hits a million views on an account that usually gets 10k isolates what is different about the video itself. One example post had more than 200x its account's median views.
Accounts that always get a million views may own a niche or have a known face, so their success can't be traced to the video. "I want to see that million view post cuz there is something different about it."
A converting format repeats across 5 to 20 viral posts. A real gem shows up as 5 to 20 viral posts across accounts with the same shot-by-shot structure, such as the hook demo or the alarm apps.
Formats built on famous faces or skits with actors, like Cheater Buster, are hard to copy because they depend on the people in them. Yannis wants a recipe separate from its content that reposters can remake at roughly $20 per video.
Search your category, sort by most viral, and adapt what converts. Searching Spytok for fitness, gym and workouts and sorting by most viral surfaced a 106x outlier fitness app video, including its text hook and CTA slide.

Plug in your own app or a competitor's profile to find structures. Yannis enters his own apps and adapts outlier structures from similar profiles. For an unreleased competitor to Claim, he uses Claim's profile and keeps his app undisclosed.
He maps the format exactly, then picks the variables to iterate on inside that structure, transferring the idea rather than copying the post.
Prove a converting format goes viral before building the app. Pick a niche, find the angles that already make apps jump the ranks, and get one account viral with that format a couple of times before building. The format already converts, so only virality is left to prove.
"I wouldn't build my app without trying to go viral first with a high converting format."
A small shift in intent can turn views into installs. Keeping the same creative but swapping "post-breakup activity" for exam procrastination made Yannis's app jump in the App Store in several countries.
His guess is that breakups are relatable but only people in one care, while everyone procrastinates before exams.
