KEN’S CAT LOG

Daily App Store Report 2026-09-04

eFootball™ (KONAMI) is today’s strongest new signal, appearing simultaneously in ios-games/grossing across five countries—KR #27, DE #32, GB #33, HR #37, and US #53—and entering overall/grossing in four as well. Overall, the top tier remained steady at 85%, with no movement at the top; churn was concentrated in the bottom tier (new 18%, |Δ| 9.3) and ios-utilities (348 new entries).

1. New arrivals

All 468 tracked charts were collected today, and all 468/468 are comparable with the previous collection on 2026-09-03 (0 missing). The biggest story is eFootball™ (KONAMI), which entered ios-games/grossing simultaneously in five countries—KR #27, DE #32, GB #33, HR #37, and US #53—and also appeared in overall/grossing at KR #44, DE #83, GB #89, and HR #90. On the paid side, Sightlines - Harmonic Filter entered ios-music/paid at GB #7, DE #9, US #16, and JP #74, while Rain Radar Pro entered ios-weather/paid at KR #14, HR #22, JP #40, and GB #45. Autodarts: Darts Scorer appeared in ios-sports/grossing in three countries, while also taking GB free #1 and HR free #3.

2. Risers over the period

The reference date, 2026-08-24, was only 11 days ago and is the oldest collection date in the archive. Note that this is not yet a full month of data. Gains were concentrated in JP paid charts and US finance: Oblique Strategies SE #5 (+93), 建設機械・建築施工 #16 (+82), Yu-Gi-Oh! Master Duel #14 (+78); in the US, Debt Manager #14 (+71) and 10BII 금융 계산기 #18 (+69). Apps absent on the reference date but now at #1 include Pantry Snapper (JP), スマスロ 甲鉄城のカバネリ (JP, also #1 in overall/paid), and MapQuest (US overall/free).

3. Trends by tier

The top tier was held 85% / new 2% / |Δ| 2.8; the mid tier 81% / 7% / 6.4; and the bottom tier 71% / 18% / 9.3. Churn is clearly happening at the long tail. Google held the most slots across all three tiers (104 / 147 / 66), while the top remains highly concentrated.

4. Trends by country

HR had the most new entries at 1036 and the loosest top-10 retention at 82%, while the US had 860 new entries but the strongest retention at 89%. The cross-market hits appearing in the top 10 across all six countries were TestFlight, Duolingo, Procreate Pocket, and Minecraft. By contrast, strongly local titles included Meteocentar (HR free #1), the FC Tokyo Official App (JP free #1), and 해피포인트 (KR overall/free #4).

5. Trends by category

The categories with the most new entries were ios-utilities with 348 (80% top-10 retention) and ios-music with 342. ios-developer-tools and ios-reference had the lowest retention, at 79%. In contrast, ios-photo-video had 91% retention, while ios-shopping, with 62 new entries, was the quietest category.

Key findings

1. eFootball™ entered ios-games/grossing in five countries on the same day, and overall/grossing in four

KONAMI’s eFootball™ newly entered ios-games/grossing at KR #27, DE #32, GB #33, HR #37, and US #53, while also entering overall/grossing the same day at KR #44, DE #83, GB #89, and HR #90. Rather than appearing in a single market, monetization appears to have launched simultaneously across regions—the earliest clear signal in today’s data of a “new wave.” KONAMI is also gaining momentum in JP, where Yu-Gi-Oh! Master Duel rose to ios-games/grossing #14 (+78), suggesting movement across the company’s titles.

Confidence: High

2. Paid niche tools are appearing across multiple countries at once: Sightlines (music), Rain Radar Pro (weather), and KITT (entertainment)

Sightlines - Harmonic Filter entered ios-music/paid at GB #7, DE #9, US #16, and JP #74; Rain Radar Pro entered ios-weather/paid at KR #14, HR #22, JP #40, and GB #45; and KITT - Systems Activated entered ios-entertainment/paid at GB #4, US #18, and DE #38. All are single-purpose paid apps from small developers, resonating simultaneously in Europe, North America, and Asia. This is evidence that the single-purpose paid-tool format is working right now.

Confidence: High

3. Autodarts: Darts Scorer captured three European countries in both free and grossing charts

It newly entered ios-sports/grossing at DE #9, GB #14, and HR #30, while also ranking GB #1 and HR #3 in free. Free and grossing traction appearing on the same day suggests installs and monetization are growing together, making an event-driven effect more likely than a one-off exposure. ios-sports is also active overall, with 250 new entries and 83% top-10 retention.

Confidence: High

4. The reference date of 2026-08-24 is only 11 days ago; “monthly” gains are concentrated in JP paid and US finance

The reference date is the archive’s oldest collection date, so there is not yet a full month of history (only 11 days). Even so, the largest gains are concentrated in JP: Oblique Strategies SE #5 (+93), 建設機械・建築施工 #16 (+82), Noms #21 (+79), and Yu-Gi-Oh! Master Duel #14 (+78). In the US, calculator and budgeting apps in ios-finance/paid rose together: Debt Manager #14 (+71), 10BII 금융 계산기 #18 (+69), CalcTape #28 (+67), Adding Machine 10Key #40 (+59), and GigNotes #22 (+58). At the country level, only JP and US had reported period gains; DE, GB, HR, and KR had none.

Confidence: Medium

5. Absent on the reference date, now #1: Pantry Snapper (JP), スマスロ 甲鉄城のカバネリ (JP), and MapQuest (US overall/free)

Apps that were not present 11 days ago but now lead their charts include Pantry Snapper at JP ios-food-drink/paid #1, スマスロ 甲鉄城のカバネリ 海門決戦 at JP ios-games/paid #1 and overall/paid #1, and MapQuest GPS Navigation & Maps at US overall/free #1. In JP ios-food-drink/paid, new apps occupy positions #1 through #4, indicating category-wide turnover.

Confidence: High

6. Movement is concentrated at the tail: bottom has new 18% and |Δ| 9.3, versus top at new 2% and |Δ| 2.8

the top tier (ranks 1–10) was extremely stable, with held 85%, only 2% new, and average movement of 2.8. The mid tier (ranks 11–50) was held 81% / new 7% / |Δ| 6.4, while the bottom tier (ranks 51–100) was held 71% / new 18% / |Δ| 9.3; most of today’s churn occurred below rank 51. For new entrants, the 51–100 range is more accessible, but also harder to remain in.

Confidence: High

7. Google holds the most slots across top, mid, and bottom tiers, while the top is dominated by major players

By number of retained slots, Google ranked first in every tier—104 top, 147 mid, and 66 bottom—followed by Microsoft Corporation at 31 / 83 / 51. Combined with the fact that only 2% of the top tier is new, the top 10 is effectively locked in by established major products, leaving little room for new releases to break through quickly.

Confidence: High

8. By market, HR is the most fluid (1036 new entries, 82% top-10 retention), while the US is the most rigid (89% retention)

All 78 charts are comparable in each of the six markets. New-entry volume was HR 1036 > DE 1000 > GB 924 > US 860 > JP 780 > KR 748, while top-10 retention was lowest in HR at 82% and highest in the US at 89%. As a smaller market, HR makes it easier for new titles to reach the top: Lainie - Relationship Coach reached ios-lifestyle/paid #1 and Meteocentar reached ios-weather/free #1 immediately after appearing. HR is an accessible market for test launches.

Confidence: High

9. Clear divide between global top-10 staples in all six countries and local #1 titles in only one market

TestFlight ranked #1 in DE/GB/HR/JP/KR/US, while Duolingo and Procreate Pocket were also #1 in all six markets. Minecraft was #1 in five markets and #2 in JP; Microsoft Teams was #1 in five markets and #8 in KR. In contrast, the FC Tokyo Official App (JP ios-sports/free #1), Meteocentar (HR), and 해피포인트 (KR overall/free #4) are entirely local. Global slots are occupied by established favorites, leaving the practical entry opportunity in locally relevant contexts.

Confidence: High

10. Category turnover differs sharply: ios-utilities (348 new entries, 80% retention) and ios-developer-tools/ios-reference (79% retention) move most, while ios-shopping (62 new entries) and ios-photo-video (91% retention) are static

New entries were especially high in ios-utilities at 348, ios-music at 342, and ios-education at 315. The lowest top-10 retention was in ios-developer-tools and ios-reference at 79%, followed by ios-utilities at 80%. At the opposite end, ios-photo-video was at 91%, while ios-news and ios-shopping were at 89%; ios-shopping had only 62 new entries, the least turnover of any category. Tools, reference apps, and developer-focused apps have the most open seats today.

Confidence: High

11. AI coding and local-LLM apps dominate developer-tools grossing; Reins reached #6 (+93) in DE

In ios-developer-tools/grossing, Cursor ranked JP #1, KR #1, DE #2, GB #2, US #2, and HR #6. Replit ranked #1 in DE/GB/HR/US, #4 in JP, and #4 in KR. In addition, Reins: for Ollama & LM Studio reached DE #6 (+93), one of the largest increases from the previous collection, while Remote Pi - Coding Agent entered free charts simultaneously in three countries: HR #35, KR #73, and JP #94. Developer-focused AI clients have a firmly established top tier, while new titles continue to enter the tail.

Confidence: High

12. Monster Loop reached #4 (+96) in JP free games, the day’s largest increase from the previous collection

モンスターループ:獣神転生 (SuperNova Overseas Limited) reached #4 in JP ios-games/free, up +96 from the previous collection—among the largest daily gains across all markets. It was also absent on the reference date, and its current #4 position suggests a post-launch surge. Wild Water World also newly entered JP free games at #5.

Confidence: High

Recommended actions

  • Turn eFootball™’s simultaneous grossing-chart appearance in five countries (KR #27 through US #53) and its entry into overall/grossing in four countries into a breaking-news item, tying it to KONAMI’s broader momentum, including Yu-Gi-Oh! Master Duel at JP #14 (+78). Confirm in tomorrow’s collection whether the rankings hold or reflect a one-day event effect.
  • Make “single-purpose paid apps from small developers” today’s editorial angle. Cover Sightlines - Harmonic Filter (ios-music/paid, GB #7 through JP #74), Rain Radar Pro (ios-weather/paid, four countries), OwnTime. (ios-productivity/paid, DE #6 and US #7), and Stay On Target 1138 (ios-utilities/paid, HR #5) side by side.
  • Entry opportunities are concentrated in ios-utilities (348 new entries, 80% top-10 retention), ios-developer-tools, and ios-reference (79% retention). Conversely, deprioritize ios-shopping (62 new entries) and ios-photo-video (91% retention), where there is little movement to capture today.
  • Use HR (1036 new entries, 82% top-10 retention) as the priority market for test launches and early-signal validation, then use the US (89% retention) to validate established traction. HR has actual examples of immediate #1 rankings, such as Lainie and Meteocentar.
  • Treat the cluster of gains in US ios-finance/paid (Debt Manager +71, 10BII +69, CalcTape +67, Adding Machine +59, GigNotes +58) as a “short-term collective movement,” explicitly noting that the reference date was 11 days ago; do not present it as a definitive monthly trend.
  • Because the reference date is only 11 days before the target date and does not yet cover a full month, defer use of the term “monthly” until subsequent daily reports, or consistently state the number of days alongside it. Reassess the reference-date treatment once 30 days of archive data has accumulated.

Data quality notes

Collection was complete: all 468 charts / 45,733 rows for 2026-09-04 were obtained (0 missing). All 468/468 charts are comparable with the previous collection on 2026-09-03, with no missing data caused by non-comparability. However, the monthly reference date of 2026-08-24 is the oldest collection date in the archive and falls only 11 days before the target date. Therefore, “monthly gains” are actually changes over 11 days and cannot be read as month-long trends. In the country-level breakdown, only JP and US had reported period gains; DE, GB, HR, and KR had no qualifying rows (the report is limited to the top 30, so this does not rule out smaller gains outside the published list). In addition, rating data is missing for 274,354 records, so today’s analysis is based solely on rankings, appearances, and movement; no judgments rely on rating scores. Rows from charts without a previous collection are not counted as new arrivals.
