KEN’S CAT LOG

Daily App Store Report 2026-09-28

Today's most important signal is DramaBox (STORYMATRIX PTE. LTD.) appearing on the same day across three surfaces—ios-entertainment grossing, free, and overall grossing—in all six markets of DE/GB/HR/JP/KR/US (HR #4 / GB #6 / DE #9 / KR #11 / US #11 / JP #14). This should be read not as a rise on a single chart, but as a simultaneous multinational launch of short-form drama monetization.

1. New arrivals

DramaBox entered ios-entertainment/grossing in all six DE/GB/HR/JP/KR/US markets on the same day (HR #4, GB #6, DE #9, KR #11, US #11, JP #14). It also appeared simultaneously in overall/grossing (HR #26 to JP #94) and ios-entertainment/free (KR #28 to JP #86). Its presence across paid, free, and overall charts is clearly stronger than an appearance on a single chart. On the paid side, small utilities spread across markets: CalCs - Calendar Complications ranked US #5 / HR #6 / GB #7 / DE #14; Rain Radar Pro appeared in five markets; and 색의 바퀴 + Osmosi AI and Speech to Text appeared in six markets. The highest-ranked single-market arrivals were Wann war's? at JP #1 (ios-productivity/paid) and Layla at HR #1 (ios-entertainment/paid).

2. Monthly risers

The reference date is 2026-08-29 (30 days ago). However, this is the oldest collection date in the archive, so the figures should be interpreted with the understanding that there is not yet a continuous month-long series. The largest increase was KI Video Generator / AI Maker in the US, reaching ios-graphics-design/free #1 (+99), followed by Zengo in HR at #5 (+93), DFB Event-App in DE at #7 (+92), and ふるさと納税 さとふる in JP at #5 (+91). Fifteen apps were absent on the reference date and are now in the top 20. BMW BERLIN-MARATHON 2026 in DE reached ios-sports/free #1 and overall/free #1, while also taking sports/free #1 in GB—a classic example of event-driven demand.

3. Trends by tier

The top tier (ranks 1–10; 4,675 slots) was nearly fixed, with 85% held, 2% new, and average movement of 2.9. The middle tier (11–50) was 81% / 7% / 6.6, while the bottom tier (51–100) was 70% / 19% / 9.7, meaning most churn occurred in the lower ranks. Google led top-tier occupancy with 114 slots, followed by Guild of Master Craftsman with 28, Instagram with 27, OpenAI with 23, and AMZN with 22. The practical entry point for newcomers is rank 51 or lower.

4. Trends by market

DE had the most new entrants at 1,087, followed by HR 1,036, GB 967, US 937, JP 790, and KR 704. US top-10 charts were the most stable at 89% held, while HR was the least stable at 81%. Global hits appearing in the top 10 across all six markets included TestFlight (six countries at #1), Replit, Duolingo (grossing #1 in all six countries), Procreate Pocket (six countries at #1), Minecraft, and LinkedIn. In contrast, Love Island Adria (HR #1), さとふる, 地震観測情報WATCH (JP #1), and 토스 비즈니스 (KR) were entirely local.

5. Trends by category

New entrants were most numerous in ios-utilities (363), ios-education (330), and ios-music (308), while ios-shopping stood out with only 57. Top-10 charts were most stable in ios-photo-video (92%), ios-social-networking (90%), and ios-games (89%), while ios-developer-tools moved the most at 79%. In developer tools, paid newcomers included WebPeek at DE #3, Binarrator at GB #4, and CodexBar at GB #5. Web Inspector for Safari reached GB #3 (+76 day over day / +84 versus the reference date).

Key findings

1. DramaBox enters three charts simultaneously across six markets on the same day — a coordinated launch for short-form drama monetization

DramaBox - 영화와 숏폼 드라마 (STORYMATRIX PTE. LTD.) entered ios-entertainment/grossing on the same day at HR #4, GB #6, DE #9, KR #11, US #11, and JP #14. It also entered overall/grossing (HR #26, GB #37, KR #48, US #70, DE #71, JP #94) and ios-entertainment/free (KR #28, HR #30, GB #54, US #55, DE #78, JP #86). Movement across free, paid, and overall surfaces on the same day points to a coordinated multinational rollout rather than a one-off promotion, making it a sound reason to evaluate short-form drama initiatives today.

Confidence: High

2. Small paid utilities enter multiple countries simultaneously — CalCs spans four markets, including US #5

CalCs - Calendar Complications (Akihiro Usui) entered ios-utilities/paid simultaneously at US #5, HR #6, GB #7, and DE #14. The same pattern appeared with 색의 바퀴 + Osmosi AI (ios-graphics-design/paid, HR #34 to GB #85) and Speech to Text : Voice to Text (ios-social-networking/paid, HR #40 to KR #69) in six markets, while AdBlock appeared in four. Low-priced widget and conversion utilities are rising across multiple countries at once; for a review-focused piece, the higher-ranking CalCs makes the strongest visual centerpiece.

Confidence: High

3. Weather and disaster-preparedness cluster expands across countries on the same day — Rain Radar Pro in five markets, myENV in four, and a Japanese earthquake app at #1

Rain Radar Pro - 실시간 날씨 지도 entered ios-weather/paid at KR #14, HR #22, DE #40, JP #40, and GB #48, while myENV entered ios-weather/free at KR #44, JP #49, GB #57, and DE #88. In Japan, 地震観測情報WATCH reached ios-weather/paid #1 (+80 day over day and +80 versus the reference date). ios-weather had an 82% top-10 hold rate, looser than average, indicating a category where seasonal and disaster-related concepts can gain traction.

Confidence: High

4. The largest rise versus the reference date was a US AI video-generation app, up 99 places to free #1

KI Video Generator / AI Maker (Hungry Birds) reached #1 in US ios-graphics-design/free, up 99 places from the 2026-08-29 reference date. Also in the US, Giggles: Videos & Trends reached ios-magazines-newspapers/free #1 (+83). AI creation also showed strength on monetization charts: Kling AI was top 10 in six markets (grossing: KR #1, DE #2, GB #2, HR #2, JP #2, US #3); Movira in GB rose +82; and Google Gemini in Japan reached ios-productivity/grossing #5 (+88). AI video and image generation is the only theme showing both rising momentum and established staying power.

Confidence: High

5. Event-driven apps jump from absent on the reference date to the top — BMW BERLIN-MARATHON and sports apps across markets

BMW BERLIN-MARATHON 2026 (Mika timing) was absent on the 2026-08-29 reference date, but this time ranked #1 in DE ios-sports/free and overall/free, as well as #1 in GB ios-sports/free. The same pattern includes DFB Event-App in DE at #7 (+92), 7days Performance in GB at #9 (+91), Harry's LapTimer Rookie at GB #8 (+91), and FOX Sports in the US at #7 (+90). ios-sports had an 81% top-10 hold rate and 269 new entrants, demonstrating numerically that event-timed initiatives work.

Confidence: High

6. The top is fixed while the bottom churns — top: 85% held / 2% new; bottom: 70% held / 19% new

The top tier (ranks 1–10; 4,675 slots) was 85% held, 2% new, with average movement of 2.9. The middle tier (11–50; 18,537 slots) was 81% / 7% / 6.6, and the bottom tier (51–100; 22,489 slots) was 70% / 19% / 9.7. Most newcomers emerged below rank 51. Top slots are controlled by a small group of major publishers—Google with 114, Guild of Master Craftsman Publications Ltd with 28, Instagram, Inc. with 27, OpenAI OpCo, LLC with 23, and AMZN Mobile LLC with 22—so discovering opportunities in the lower tier has a better hit rate than waiting for turnover at the top.

Confidence: High

7. By market, the US is the most stable (89% top-10 held), HR is the most fluid (81%), and DE has the most newcomers (1,087)

New entrants totaled DE 1,087, HR 1,036, GB 967, US 937, JP 790, and KR 704. Top-10 hold rates were US 89%, GB 86%, KR 85%, JP 84%, DE 83%, and HR 81%. All 78 of 78 charts were comparable in each of the six markets, so these differences reflect market characteristics rather than missing data. DE and HR are suitable markets for discovering new faces, while the US is the better source for stories about durable incumbents.

Confidence: High

8. Global staples at or near #1 in all six markets — TestFlight, Duolingo, Procreate Pocket, and Minecraft

TestFlight was #1 in ios-developer-tools/free across DE/GB/HR/JP/KR/US. Duolingo was #1 in ios-education/grossing in all six countries, Procreate Pocket was #1 in ios-graphics-design/paid in all six, and Minecraft was #1 in DE/GB/HR/KR/US ios-games/paid and #2 in JP. LinkedIn was #1 in ios-business/grossing in DE/GB/HR/US, #2 in KR, and #3 in JP. These are not today's movers, but stable reference points for comparison.

Confidence: High

9. Strong, exclusively local movement — Love Island Adria #1 in HR, さとふる +91 in JP, and 토스 비즈니스 +83 in KR

In HR, Love Island Adria (RTL Hrvatska) ranked #1 in ios-entertainment/free, Layla ranked #1 in paid, and BHRT reached ios-magazines-newspapers/free #11 (+88). In JP, ふるさと納税 さとふる reached ios-lifestyle/free #5 (+91), while 看護学生必携!関連図アプリ reached #9 (+85). In KR, 토스 비즈니스 reached ios-business/free #13 (+83), and tesly - 테슬라 차계부 reached ios-navigation/grossing #4 (+83). None of these stories spilled into other markets, so country-specific angles are needed.

Confidence: High

10. ios-developer-tools has the most turnover (79% top-10 held) — three new paid apps and an increase of +84

ios-developer-tools had the lowest top-10 hold rate among all 26 categories, at 79%. On paid charts, WebPeek — Web Inspector entered at DE #3, Binarrator - binary translator at GB #4, and CodexBar Usage Monitor at GB #5. Web Inspector for Safari reached GB #3 (+76 day over day / +84 versus the reference date), while GrafanaUI reached US #12 (+85 versus the reference date). On monetization charts, PostHog Analytics - Hogly entered at HR #3 and PushWard at DE #6. Developer-focused niches offer more openings at the top and are worth covering.

Confidence: High

11. Most turnover occurs in ios-utilities (363 newcomers) and ios-education (330), while ios-shopping has the fewest at 57

New entrants were most numerous in ios-utilities (363), ios-education (330), ios-music (308), ios-reference (276), ios-health-fitness (269), and ios-sports (269). By contrast, ios-shopping had just 57, an order of magnitude lower. For top-10 holds, ios-photo-video at 92%, ios-social-networking at 90%, and ios-games at 89% were notably stable. For fresh story ideas, focus on utilities, education, and music; for comparisons of established leaders, photo-video and social-networking are better suited.

Confidence: High

12. Specialized medical and healthcare apps concentrate at high ranks in KR and HR

Easy Anatomy 3D mit Sprach-KI entered ios-medical/free simultaneously in three markets: HR #6, US #41, and DE #67. In KR, Harrison's Manual of Medicine ranked ios-medical/grossing #3, EchoLab entered ios-medical/paid #3, and 맘찌 AI reached #9 (+87). In HR, ScanBaby learn baby ultrasound reached #8 (+84). ios-medical saw 247 new entrants and an 83% top-10 hold rate, offering an angle around high-priced apps for professional users.

Confidence: Medium

13. The 2026-08-29 reference date is the oldest date in the archive — “monthly” means a 30-day gap, not a completed continuous series

The reference date, 2026-08-29 (30 days earlier), is the earliest collection date available in the archive. Therefore, changes such as +99 and +93 are differences between two points in time; the path between them—whether a temporary spike or sustained rise—cannot be confirmed. To avoid misreading, prioritize apps that moved in the same direction both day over day (2026-09-27) and versus the reference date. Examples include Web Inspector for Safari (+76 day over day / +84 versus the reference date) and 地震観測情報WATCH (+80 / +80).

Confidence: High

Recommended actions

  • Make DramaBox's simultaneous entry across six markets—ios-entertainment grossing and free, plus overall grossing—the main story for today. HR #4 / GB #6 / DE #9 are the most visually compelling figures, and the fact that free and paid moved together distinguishes it from a one-off spike.
  • Turn the cross-market cluster of small paid utilities into one piece: CalCs at US #5 / HR #6 / GB #7 / DE #14, Rain Radar Pro in five markets, and Speech to Text in six. Each is weaker on its own, but their same-day, multi-country pattern gives the article its backbone.
  • Designate ios-developer-tools (lowest top-10 hold rate at 79%) and ios-utilities (highest new entrants at 363) as ongoing monitoring categories. The top ranks open up more readily, allowing new faces such as WebPeek DE #3 / Binarrator GB #4 / CodexBar GB #5 to be surfaced daily.
  • Cover AI creation in one integrated piece combining “growth” (US KI Video Generator +99, GB Movira +82, JP Google Gemini +88) with “establishment” (Kling AI in the top 10 across six markets). Tracking them individually would fragment the same story.
  • Secure DE/GB's BMW BERLIN-MARATHON 2026 (sports free #1; DE overall free #1) and DFB Event-App +92 today as event-driven stories. Event apps have a short freshness window and may decline by the next day.
  • From tomorrow onward, add the sign of day-over-day movement alongside large changes versus the reference date. With only two reference points currently available, call something “sustained growth” only when both movements point in the same direction, such as Web Inspector for Safari at GB #3 and 地震観測情報WATCH at JP #1.
  • Record the 274,166 missing rating values as a collection-side issue and defer ranking concepts based on ratings for now. Focus on angles that can be supported by rank alone.

Data quality notes

Collection is complete. All 468 target charts for 2026-09-28 were collected (0 missing), and 45,701 rows were analyzed. Comparison with the previous day, 2026-09-27, is also valid for all 468 of 468 charts. All six markets have 78 of 78 comparable charts, so market differences in held/new rates do not result from missing data. There are two limitations. (1) The 2026-08-29 reference date is the oldest collection date in the archive. Although it is 30 days earlier, there is not yet a continuous month-long series, so “monthly growth” must be read as a difference between two points in time. (2) Rating data is missing for 274,166 records, so analysis based on rating scores or rating counts is not possible this time. All judgments are based solely on rank, category, and market. Rows from charts that did not exist on the previous day are not counted as “new,” so there are no false new arrivals caused by incomparable charts.
