Daily App Store Report 2026-09-30

On 2026-09-30, DRAGON BALL Z 폭렬격전 appeared simultaneously in overall/grossing charts across five countries—DE #26, US #26, GB #46, KR #68, and HR #98—while Game Informer 매거진 took DE #1 and HR #3 in news/free. Same-day multi-country launches were the main story. All 468 charts were collected and are fully comparable; developer-tools was the most volatile category, with 76% top-10 retention.

1. New Entries

Today's strongest signal is DRAGON BALL Z 폭렬격전 (Bandai Namco), which entered overall/grossing simultaneously in five countries—DE #26, US #26, GB #46, KR #68, and HR #98—and also appeared in ios-games/grossing at DE #9, GB #13, KR #35, and HR #43. In US ios-games/grossing, it climbed to #6 (+90) in a single day. Next, Game Informer 매거진 entered ios-news/free at DE #1, HR #3, JP #29, and KR #30. On the paid side, FrameDrop: Camera Import (DE #5 / US #7 / GB #20) and AGAIN. Rehearsal Notes (DE #7 / US #8 / GB #9) launched across three Western markets simultaneously. Developer tools also saw Macky (GB #18 to JP #88) and herdrup (US #70 to GB #97) spread across four countries.

2. Sharp Monthly Rises

The reference date is 2026-08-31 (30 days ago), but it is the oldest date in the archive, with no earlier history available ("there is not yet a full month of data"). The largest rise was Game Informer 매거진 at GB ios-news/free #2 (+95). This was followed by FUT.GG at DE #3 (+91), Empower You at HR #7 (+91), FUTBIN at DE #10 (+90) / HR #9 (+88), and Simran at GB #10 (+90). Entries absent on the reference date but now within the top 20 were concentrated in HR, including paid #1 apps such as MapleRead CE, Aiko, Flush Toilet Finder Pro, and play_music_theory.

3. By Tier

top (1–10) was nearly fixed, with 85% held, 2% new, and |Δ| 2.8. mid had 81% held, 7% new, and |Δ| 6.5; bottom (51–100) had 70% held, 18% new, and |Δ| 9.3, showing that turnover is concentrated in the lower ranks. Google held the most slots across every tier (top 122 / mid 149 / bottom 82), followed by Microsoft.

4. By Country

All 78 charts in each country are comparable. Top-10 retention was strongest in the US at 88%, KR at 87%, and JP at 85%, while HR was the most active at 82% (with 980 new entries, the most of any market). Developer tools were the common thread: TestFlight ranked #1 in all six countries, and Cursor, GitHub, and Replit were also top-10 in all six. The same was true for Duolingo, Paprika, Minecraft, and Kling AI. In contrast, FC 27-related apps in DE, ＪＩＣＣスマホアプリ at JP #4, and mojaBIPA at HR #4 were local-specific.

5. By Category

The most volatile category was ios-developer-tools (76% top-10 retention), followed by ios-sports at 80% and ios-graphics-design at 80%. Conversely, ios-social-networking at 94% and ios-productivity at 91% barely moved. New-entry volume was especially high in ios-utilities (354) and ios-music (351), both driven by small paid apps such as Call Ranger at HR #3 and Handy Guitar Lab at KR #4.

Key Findings

1. DRAGON BALL Z 폭렬격전 enters overall/grossing in five countries on the same day, reaching US games/grossing #6 (+90)

Bandai Namco's DRAGON BALL Z 폭렬격전 entered overall/grossing simultaneously at DE #26, US #26, GB #46, KR #68, and HR #98, as well as ios-games/grossing at DE #9, GB #13, KR #35, and HR #43. In US ios-games/grossing, it reached #6 (+90) versus the prior day. This is not a single-market appearance, but a simultaneous multi-country rise in monetization charts—the strongest new-entry signal in today's data. It is worth tracking IP initiatives such as collaborations or revivals.

Confidence: High

2. Game Informer 매거진 reaches DE #1 and HR #3 in ios-news/free; GB is #2 with a monthly +95

Gameinformer’s Game Informer 매거진 entered ios-news/free on the same day at DE #1, HR #3, JP #29, and KR #30; in GB, it rose +95 versus the 2026-08-31 reference date to #2. News is normally a stable category, with 87% top-10 retention, making a new app taking the top spot unusual. Demand for gaming media appears to be emerging from Europe.

Confidence: High

3. ios-developer-tools is the most volatile category (76% top-10 retention)—with two apps launching in four countries

Among 26 categories, it had the lowest top-10 retention at 76% (170 new entries). Two apps also appeared in multiple countries on the same day: Macky (GB #18, US #58, DE #69, JP #88) and herdrup: agents in your pocket (US #70, KR #77, DE #93, GB #97). New entrants continue to arrive from the lower ranks, leaving room for AI and coding-assistant products.

Confidence: High

4. The top developer tools are the same across all six countries—TestFlight is #1 everywhere, while Cursor/GitHub/Replit are top-10 in all six

TestFlight ranked #1 in ios-developer-tools/free across DE/GB/HR/JP/KR/US. In grossing, Cursor (HR #1, JP #1, GB #2, US #2, DE #4, KR #7), Replit (GB #1, KR #1, US #1, DE #2, JP #2, HR #5), and GitHub (DE #1, HR #2, GB #3, JP #3, US #3, KR #4) were all top-10 across all six countries. Although the category as a whole is volatile, its leaders are globally entrenched, so targeting underserved needs in the lower ranks is more realistic than competing at the top.

Confidence: High

5. Turnover is concentrated in the lower ranks: bottom has 18% new and |Δ| 9.3, while top has 85% held and |Δ| 2.8

top (1–10) contained 4,675 slots, with 85% held, 2% new, and an average movement of 2.8. mid (11–50) had 18,540 slots, with 81% held, 7% new, and 6.5. bottom (51–100) had 22,475 slots, with 70% held, 18% new, and 9.3. New entries require monitoring ranks below #51; the top is dominated by Google (122 slots), Microsoft (30), Instagram (30), and others, leaving short-term product opportunities in mid/bottom.

Confidence: High

6. HR was the most active market (980 new entries; 82% top-10 retention), while US/KR were the most stable (88%/87%)

Each country has 78 charts. HR had the most new entries at 980 and the lowest top-10 retention at 82%, compared with US at 88%, KR at 87%, and JP at 85%. HR also concentrated cases that were absent on the reference date but now ranked #1: MapleRead CE (ios-books/paid #1), Aiko (ios-productivity/paid #1), Flush Toilet Finder Pro, Weather & Rain Radar Forecast, KennysGifs, and Coach Me. Smaller markets can see rankings shift with relatively few installs, making them useful for test launches.

Confidence: High

7. DE ios-sports has three EA FC 27-related monthly surges (+91 / +90 / +87)

FUT.GG - FC 27 Evos & Prices reached DE ios-sports/free #3 (+91), FUTBIN FC 27 Evolutions & More reached DE #10 (+90) and HR #9 (+88), and DFB Event-App reached DE #5 (+87). ios-sports itself is volatile, with 80% top-10 retention and 265 new entries. Demand for FC 27 companion apps is clearly linked to the start of the season, making this a timely moment for content around guides, prices, and evolution information.

Confidence: High

8. Paid charts see small indie tools launch across multiple countries at once (FrameDrop, AGAIN. Rehearsal Notes, SimpleMind Pro)

FrameDrop: Camera Import entered ios-photo-video/paid at DE #5, US #7, and GB #20; AGAIN. Rehearsal Notes entered ios-music/paid at DE #7, US #8, and GB #9; SimpleMind Pro entered ios-productivity/paid at GB #37, JP #39, DE #42, and US #83; and Gravity – Minimal Notes entered at DE #15, US #29, and GB #55. Each is a single-purpose paid app, with Western markets reacting on the same day. This is a promising pattern for products that small teams can build.

Confidence: High

9. ios-utilities (354 new entries) and ios-music (351) are the biggest gateways for new inflows

New-entry volume was especially high in these two categories (utilities 354; music 351), with top-10 retention of 82% for utilities and 86% for music. Examples include Call Ranger: Spam-Anrufblocker (HR #3, KR #18, JP #44), Handy Guitar Lab for MS-70CDR+ (KR #4), and Smart Metronome & Tuner + (KR #9, monthly +86). Niche practical tools and instrument-practice support have broad entry opportunities.

Confidence: High

10. Categories that barely move: ios-social-networking 94%, ios-productivity 91%, ios-magazines-newspapers 89%

The highest top-10 retention was in ios-social-networking at 94% (with just 138 new entries, among the fewest), followed by ios-productivity at 91%, ios-magazines-newspapers at 89%, and ios-books/ios-finance at 88%. Existing players are entrenched here, so short-term effects from new launches are limited. However, Aiko reached HR #1 and JP #9 in paid productivity, suggesting that paid niches—not the leading free ranks—are the entry point.

Confidence: Medium

11. AI image and video generation reaches the global top 10 in both free and grossing charts (Kling AI)

Kling AI: AI Image&Video Maker ranked in ios-graphics-design/free at DE #1, HR #1, KR #1, GB #3, JP #3, and US #3; in grossing, it ranked HR #1, KR #1, DE #2, GB #2, JP #2, and US #3. The category itself is volatile, with 80% top-10 retention; in the US, AI Maker: Photo Video Filters rose +81 monthly to #1, while in HR, Sorax: Create AI Video newly entered at grossing #3. Demand is strong, but competition at the top moves quickly.

Confidence: High

12. Collection is complete: 468 charts / 45,690 rows, 0 missing, and all 468 are comparable with the prior run

All 468 target charts for 2026-09-30 were collected (0 missing), spanning 6 countries × 26 categories and 45,690 rows. All 468 charts were also comparable with 2026-09-29, including 78/78 charts per country. Therefore, today's “new entries” do not include apparent newness caused by unavailable comparison data and can be read as genuine inflows.

Confidence: High

Recommended Actions

  • Make the simultaneous five-country grossing rise of DRAGON BALL Z 폭렬격전 the top tracking priority. Whether US ios-games/grossing #6 (+90) holds for several days will distinguish a temporary event-driven spending spike from a sustained comeback. The product team can use the monetization-chart behavior of IP collaborations and revival titles as a subject.
  • Examine Game Informer 매거진 as a case of a new entrant breaking into a stable category. Despite ios-news having 87% top-10 retention, it reached DE #1 and HR #3, while GB rose +95. Confirm the launch or rebranding background and turn it into an article or video about room for entry in the news category.
  • Make ios-developer-tools (76% top-10 retention, the most volatile category) a standing monitoring area. The top is fixed across six countries by TestFlight / Cursor / GitHub / Replit, so focus below #50. A daily process that captures four-country simultaneous entrants like Macky and herdrup will be effective.
  • Make DE’s EA FC 27 companion-app demand (FUT.GG +91, FUTBIN +90, DFB Event-App +87) this week’s content. Right after the season launch is when search demand for prices and evolution information is rising.
  • Package the simultaneous multi-country arrival of small paid tools (FrameDrop, AGAIN. Rehearsal Notes, SimpleMind Pro, Gravity) into a piece on winning patterns for single-purpose paid apps. The 354 new entries in ios-utilities and 351 in ios-music support this trend.
  • Always include the bottom tier (51–100, 18% new / |Δ| 9.3) in new-entry scans. The top has 85% held and |Δ| 2.8, offering little information; watching only that range would miss nearly every new face today.
  • Use HR for test launches and early-momentum observation (980 new entries; 82% top-10 retention). Six apps went from absent on the reference date to #1, showing that small volumes can move rankings.
  • Ask the operations team to collect the missing ratings data (274,162 records). Time-series rating and review-count data are needed to distinguish genuine download-driven rises from rating manipulation.

Data Quality Notes

Collection was complete: all 468 target charts for 2026-09-30 were present (0 missing), with 45,690 rows analyzed. Comparisons with 2026-09-29 were also valid for all 468/468 charts, so today's new entries do not include apparent newness caused by missing prior charts. There are two limitations. (1) The monthly reference date, 2026-08-31, is the oldest date in the archive, with no earlier history (the data notes that there is not yet a full month of data). Therefore, monthly changes such as “+95” are not month-long trends, but snapshot differences between the reference date and today. (2) rating data is missing for 274,162 records, so this analysis cannot validate ranking movement using rating scores or rating counts. It relies only on ranks and appearances/disappearances. However, today’s important new entries, including DRAGON BALL Z 폭렬격전, appeared in charts with valid prior-day comparisons and are unaffected by these limitations.
