Medical is the only app category of 17 where Instagram holds more of the videos than TikTok

The order of the table is not the order of category size. Medical holds 2,643 videos, ninth of the 17, and leads on Instagram share. Business is the largest at 14,625 videos and sits in the middle of the share column at 38.1%.

Five categories sit above 44%: Medical, Navigation, Parenting, Weather and Events. Three sit below 28%: Personalization at 21.4%, News at 26.8% and Dating at 27.4%. A founder in Personalization who briefs an Instagram creator first works against a 3.7-to-1 supply ratio, at 2,199 TikTok videos to 600.

Two rows carry a lot of video against few apps. Events holds 1,481 matched videos and 25 apps in the library. Beauty holds 1,377 and 50.

We cannot say how many distinct apps produced those videos. A share in a small category can be a handful of companies' posting habits wearing a category's name.

Our browse counter runs through a subquery capped at 10,000. Above that it returns a saturation value, which means 10,000 or more and nothing else. It is not a number, so it cannot be divided by, subtracted from, or printed.

Ten categories are capped on both platforms and are excluded outright. They are Education, Entertainment, Finance, Food & Drink, Games, Health & Fitness, Lifestyle, Photo & Video, Shopping and Travel. We know each holds at least 10,000 videos on each platform and we know nothing else about the split.

Four more are capped on TikTok alone, and those keep a usable ceiling. If TikTok is at least 10,000, then Instagram's share is at most its own count divided by that count plus 10,000.

All four ceilings sit under 50%, so none of those categories can be Instagram-majority however far past the cap their TikTok counts run. Medical survives as the only Instagram-majority category across 21 of the 31, and the remaining 10 are unknown in both directions.

A ceiling is worth printing because the alternative is silence about four categories that hold real volume. Productivity alone holds at least 18,916 matched videos across the two platforms.

The two platforms hold different kinds of account. 735 of the 1,955 TikTok videos in this draw came from accounts under 10,000 followers. On Instagram it was 142 of 1,338.

Read the other end and the gap widens. 942 of the 1,338 Instagram videos, which is 70.4%, came from accounts above 100,000 followers. On TikTok the same bands hold 678 of 1,955, which is 34.7%.

That is the part of this page a founder with one budget can act on. A category weighted toward Instagram is one where the people posting about apps are mostly six-figure accounts. Where TikTok leads, sub-10,000 accounts are a live option. We measured that pattern in five categories and we are extending it to the other 17 as an expectation, not as a finding.

Every share in this article uses the browse counter on both sides, so the disagreement above changes no percentage on this page. It changes what a percentage means.

A category is a property of the app, and a video inherits it through the app it was matched to. Match a video to two apps in two categories and the facet counter records it twice. Filter the same video in the product and it appears under both filters as well.

We print both counters because a reader checking our category page against this article will find two different totals. The gap runs to 47.9% in Events. The gap is real and it is a counting rule, not an error in either number.

This is our library and not the market. Every count is a count of videos we collected and matched to an app. Scraping is driven by what customers asked about. A category with more videos is a category we collected more of, and a low count is never evidence that nobody posts. We hold organic content for 8,938 of the 34,624 apps in the library. These figures describe Apptonic's own library as of 14 August 2026. The library is a growing sample of the app market, not a census.

Fourteen of 31 categories have no share at all. Our counter stops at 10,000, and 10 categories are above it on both platforms. Four keep a ceiling and no value. The categories with the most app content are exactly the ones we cannot split. The table describes the middle and small end of the library and says nothing about the top.

We cannot report how concentrated a category is. These files hold counts and no rows. We do not know how many distinct apps or creators produced the videos in any category. Events holds 1,481 videos against 25 apps in the library, and Beauty holds 1,377 against 50. Neither figure tells us whether five companies produced most of the posting.

The follower bands come from five other categories. Education, Finance, Health & Fitness, Photo & Video and Productivity are all capped. None of them appears in the 17-category table. Their 3,293 videos were drawn newest-first per video opening across a 90-day window, which over-represents rare openings. Treat the account-size pattern as a reason to check your own category and not as a measurement of it.

Unmatched content is invisible here. A category filter resolves through the app a video is matched to. A video we hold but never matched is in none of these counts. Content is linked to apps by store links where we can find them and by name matching otherwise. Name matching is deliberately generous and it is not perfect.
