KEN’S CAT LOG

Daily App Store Report 2026-09-07

Today's (2026-09-07) strongest signal is the same-day, multi-market launch of paid apps: Rain Radar Pro entered ios-weather/paid in five markets, led by KR #14, while 2Do - Todos, Tasks & Notes simultaneously entered ios-productivity/paid in four markets, including GB #3 and DE #10. The top tier remained stable with 84% retention, while churn was concentrated in the lower tier, with 19% new entries and an average movement of 9.9.

1. New Entries

Same-day, multi-market appearances in paid charts stood out. Rain Radar Pro (DeluxeWare) appeared simultaneously in ios-weather/paid across five markets: KR #14, HR #22, JP #39, DE #40, and GB #44. 2Do - Todos, Tasks & Notes (Beehive Innovations Services) entered ios-productivity/paid in four markets: GB #3, DE #10, JP #15, and US #18. Blueprint 4-Track (MAX B HELGEMO) entered both ios-music/paid (DE #3, KR #24, JP #89) and overall/paid (GB #27, US #36, DE #89), extending beyond a single category. On the free side, Weight measurement of princess entered ios-medical/free at HR #16, GB #17, DE #46, and US #93.

2. Sharp Rise Over the Period

The reference date, 2026-08-24, was 14 days ago and is the oldest collection date in the archive; note that this is not a full month of data. The largest gain was Oblique Strategies SE (JP/ios-productivity/paid #4, +94), followed by 風水診断: 玄空飛星風水 (JP/ios-lifestyle/paid #12, +84) and Purchases (US/ios-finance/paid #14, +82). Among apps absent on the reference date that entered the top 20 this time, the Japanese pachislot title スマスロ とある魔術の禁書目録2 ranked #1 in both ios-games/paid and overall/paid in JP.

3. By Tier

top (1–10) was the most stable, with held 84% / new 2% / |Δ| 2.9. mid recorded held 80% / new 7% / |Δ| 7. bottom (51–100) recorded held 69% / new 19% / |Δ| 9.9, meaning today's churn was effectively a lower-tier phenomenon. Google dominates the top tier with 105 slots.

4. By Country

All 468 charts were comparable with the previous run. US had the strongest top-10 retention at 88%, while HR was the loosest at 81%. HR had the most new entries at 1,137, while KR had the fewest at 775. Shared strength is evident in TestFlight (#1 in all six markets), Duolingo's education/grossing chart performance (#1 in all six markets), and Jump Desktop (#1 in five markets). By contrast, the JR East app (JP/overall/free #3) and 쾅냥 서바이버 (KR/ios-games/free #1) are entirely local.

5. By Category

The fastest-moving categories were ios-developer-tools (top-10 retention 76%), ios-sports (77%), and ios-navigation (78%). In contrast, ios-photo-video and ios-social-networking were largely unchanged at 89%. By number of new entries, ios-utilities ranked highest with 353, followed by ios-education with 336 and ios-music with 332.

Key Findings

1. Rain Radar Pro entered ios-weather/paid in five markets on the same day

DeluxeWare's Rain Radar Pro appeared simultaneously in the same category and chart type across five markets: KR #14, HR #22, JP #39, DE #40, and GB #44. This is a stronger signal of distribution or visibility changes than an appearance in a single chart, and may indicate that paid weather-app demand opened up simultaneously.

Confidence: High

2. 2Do entered ios-productivity/paid in four markets, reaching #3 in GB

2Do - Todos, Tasks & Notes was a new entry at GB #3, DE #10, JP #15, and US #18. It entered the top 10 immediately in GB and DE. The simultaneous movement of paid task-management slots in major English-speaking and European markets is useful input for deciding whether to publish content in this genre today.

Confidence: High

3. Blueprint 4-Track was new in both category and overall charts, reaching DE ios-music/paid #3

MAX B HELGEMO's Blueprint 4-Track entered ios-music/paid (DE #3, KR #24, JP #89) and overall/paid (GB #27, US #36, DE #89) on the same day. Its reach extends beyond the category chart into overall paid rankings, an unusual spread for a niche music tool.

Confidence: High

4. The 2026-08-24 reference date was 14 days ago, not a monthly comparison

The reference date for the "monthly rise" metric, 2026-08-24, is the oldest collection date in the archive, and there is not yet a full month of data. Figures such as +94 must be read as 14-day changes; no conclusions about seasonality or monthly cycles can be drawn.

Confidence: High

5. The biggest 14-day gains are concentrated in JP paid apps

Oblique Strategies SE (JP/ios-productivity/paid #4, +94), 風水診断: 玄空飛星風水 (JP/ios-lifestyle/paid #12, +84), Min Habit (JP/ios-lifestyle/paid #5, +79), and 有機化学 (JP/ios-education/paid #17, +77) show that large gains are concentrated in JP paid charts. Because JP's top-10 retention is stable at 84%, these gains are being driven by upward movement from the middle ranks.

Confidence: High

6. JP pachislot titles went from absent on the reference date to top positions in both games and overall charts

スマスロ とある魔術の禁書目録2 (SUNSOFT) ranked #1 in ios-games/paid and #1 in overall/paid, while スマスロ 甲鉄城のカバネリ 海門決戦 (Sammy Networks) ranked #3 in both. Neither existed on the 2026-08-24 reference date. The top of JP's paid-games space has effectively been replaced by these two titles.

Confidence: High

7. Churn is almost entirely confined to the lower tier (bottom new 19% / |Δ| 9.9)

top (1–10) recorded held 84% / new 2% / |Δ| 2.9; mid (11–50) recorded held 80% / new 7% / |Δ| 7; and bottom (51–100) recorded held 69% / new 19% / |Δ| 9.9. Most of today's movement occurred below rank 50, so projects targeting top-tier visibility should not rely on a single day's fluctuations.

Confidence: High

8. Google holds the most slots across every tier, with 105 in the top tier

In the top tier, Google holds 105 slots, followed by Guild of Master Craftsman Publications Ltd with 30, Adobe Inc. with 23, X Corp. with 23, and OpenAI OpCo, LLC with 23. In the mid tier, Google again leads with 141, followed by Microsoft with 77. The 1–10 range is structurally dominated by a small number of large companies, making the middle and lower ranks the more realistic entry point for newcomers.

Confidence: High

9. US is the most stable (top-10 retention 88%), while HR is the most fluid (81% and 1,137 new entries)

Top-10 retention was US 88%, JP 84%, DE/GB/KR 83%, and HR 81%. HR had the most new entries at 1,137, while KR had the fewest at 775. HR offers the most open slots for test distribution and early-traction validation, whereas US has a high cost of displacing established leaders.

Confidence: High

10. Several global staples rank first in all six markets

TestFlight (Apple) is #1 in ios-developer-tools/free across DE, GB, HR, JP, KR, and US. Duolingo is #1 in ios-education/grossing across all six markets, and also #1 in ios-education/free in JP, KR, and US. Jump Desktop is #1 in ios-business/paid in five markets, with US #2 as the exception. These category leaders are not viable targets as of today.

Confidence: High

11. The fastest-moving categories are developer-tools, sports, and navigation

Top-10 retention is low for ios-developer-tools at 76%, ios-sports at 77%, and ios-navigation at 78%. Conversely, ios-photo-video and ios-social-networking are stable at 89%, while ios-games is stable at 88%. In absolute terms, new entries total 353 in ios-utilities, 336 in ios-education, and 332 in ios-music. The opportunity to break into the top ranks is concentrated in developer-tools and sports.

Confidence: High

12. GB ios-developer-tools/paid has entirely new faces near the top

In GB, DroidShell #3 and Card Number Maker #4 were new entries. In US, JavaScript Blocker for Safari #4 and My Styles: Custom Website Look #5 were also new. This aligns with the category-wide top-10 retention rate of 76%. Small paid tools for developers are the genre most able to reach the top today.

Confidence: High

13. Major US title EA College Football Mobile 27 rose +76 in 14 days

It ranked #12 in US/ios-games/free, up +76 from the reference date. It is the only top US free game to show a gain of this magnitude, suggesting demand for adjacent content as a season-linked title gains traction. In the same market, UKG Pro ranked #32 in overall/free (+59).

Confidence: Medium

14. HR paid charts are led by new entries, showing clear local demand

In HR, Gus on the Go: Croatian (ios-education/paid #1), Collins Dictionary+Thesaurus (ios-reference/paid #1), and Deer Call Mixer (ios-sports/paid #1) all appeared as new #1 entries. HR is the most fluid market, with 1,137 new entries and 81% top-10 retention, and distinctly local demand for language learning, dictionaries, and outdoor activities is shaping the top ranks.

Confidence: High

15. Two free health and weather apps also entered four markets simultaneously

Sleep Cycle entered ios-health-fitness/free in four markets: HR #66, DE #74, GB #87, and JP #100. Moonlitt entered ios-weather/free in four markets: HR #51, DE #75, US #96, and JP #100. Both appeared in the lower tier and should be treated as the same type of movement reflected in bottom's 19% new-entry rate; their persistence cannot be judged from this alone.

Confidence: Medium

Recommended Actions

  • Continue tracking same-day, multi-market appearances of paid utility and productivity apps (Rain Radar Pro in five markets and 2Do in four) from tomorrow onward, and check whether they remain for two to three consecutive days. If they disappear after one day, treat them as distribution noise; if they persist, use them as evidence of real demand for paid-tool content.
  • Make GB and US ios-developer-tools/paid the priority segment today. The category's 76% top-10 retention is the lowest of all categories, and small tools such as DroidShell #3, Card Number Maker #4, and JavaScript Blocker for Safari #4 are immediately reaching the upper ranks.
  • Treat JP as a standalone topic. The two pachislot titles at ios-games/paid #1 and #3, along with the concentration of paid-app gains including Oblique Strategies SE +94, have no equivalent in the other five markets and support a Japan-only article.
  • Do not base projects covering the top tier (top-10, 84% retained, 2% new) on today's changes. The real movement is in the bottom tier (19% new, |Δ| 9.9); if writing an article, use the angle of what changed in the lower ranks.
  • Because featured (DE, GB, JP) is degraded, hold any claims based on featured placement until the next collection confirms them.
  • Whenever using reference-date comparisons, explicitly state "the 14 days since 2026-08-24" and avoid monthly wording. Do not conduct true monthly comparisons until collection dates have accumulated.

Data Quality Notes

All 468 target charts were collected, with 0 missing; 45,746 rows were analyzed. Every chart was comparable with the previous run on 2026-09-06 (468 / 468), with no non-comparable charts. However, three sources—DE/featured, GB/featured, and JP/featured—were collected in a degraded state, so rows derived from them are less reliable than the others. In addition, rating is missing from 274,387 records, so this report does not use rating-based analysis at all. The reference date for monthly comparison, 2026-08-24, was 14 days ago and is the oldest collection date in the archive. Therefore, even where it is labeled "monthly," it actually represents two-week movement, and a full month of cyclicality cannot be assessed. Rows from charts absent in the previous run are not counted as new entries, so no items were incorrectly classified as new solely because comparison was unavailable.
