KEN’S CAT LOG

Daily Google Play Report 2026-09-29

Activity on 2026-09-29 was concentrated in comics and watch faces: Mango: Comics & Manga appeared simultaneously in four countries—HR #5 / DE #9 / GB #16 / US #21—while android-watch-face saw the largest category reshuffle, with an 83% top-10 retention rate and 34 new entries. Meanwhile, ranks 1–10 remained 94% stable (average movement 0.7), with churn concentrated at the lower end of ranks 31–45 (76% retained, 13% new).

1. New Entries

The strongest signal is the simultaneous four-country debut of Mango: Comics & Manga (HR #5 / DE #9 / GB #16 / US #21). In the same android-comics/free category, Toonhub - Premium Comics entered at US #2 and HR #29. Comics free had 25 new entries and 92% top-10 retention, indicating fast turnover. Other notable entries include LiveLocate - Family Tracker (KR #10 / US #23 / GB #28), Emoji Battery: Status Bar Icon (DE #21 / HR #22 / US #29), and Screen Recorder - AZ Recorder (GB #22 / DE #34 / US #39). Google’s own Contacts (three countries across communication and android-wear) and Google Keep (US #29 / GB #39) also appeared that day.

2. Sharp Monthly Rises

The baseline date is 2026-08-30 (the oldest collection date in the archive, so there is not yet a full month of data). The biggest gains are concentrated in AI photo and video generation: AI Photo Generator: Muselab AI reached DE #2 (+43), while Momo: AI Photo & Video Maker reached US grossing #1 (+39) and free #1 (+32), followed by Hype AI at #3 (+35) and Hailuo AI at #5 (+34). Apps absent on the baseline date that are now #1 include Rotate Rings (DE / HR), PDFMaster - PDF Reader (DE tools), and PDF Reader: Viewer, Edit PDF (KR tools).

3. By Tier

top (ranks 1–10) is stable at held 94% / new 1% / |Δ| 0.7; mid is 89% / 3% / 2; bottom (ranks 31–45) is 76% / 13% / 2.7. New entries almost always enter from the lower end. Because developer values are missing, it is not possible to identify the developers occupying the top ranks.

4. By Country

top-10 retention ranges from 93% to 95%, essentially even across all six markets. GB had 129 new entries, KR 128, and US 126. Hits common to all markets include X (news #1 in all six), Duolingo, ChatGPT, Canva, and Rotate Rings. In contrast, strongly local titles include tagesschau at DE #4, Gdje je tramvaj at HR #8 (+22), and new paid entries 희담필터 #1 and 회독JLPT #2 in KR.

5. By Category

The most active category was android-watch-face (83% retained, 34 new entries), followed by android-education (90%, 32 new), android-events (90%), android-shopping (91%), and android-dating (91%). The quietest categories were android-video-players, android-business, android-finance, and android-beauty (all 98%).

Key Findings

1. Four-country simultaneous comic free entry: Mango at HR #5 / DE #9 / GB #16 / US #21, while Toonhub is #2 in the US

Mango: Comics & Manga entered four android-comics/free charts on the same day where it had not appeared on 2026-09-28: HR #5, DE #9, GB #16, and US #21. In the same category, Toonhub - Premium Comics appeared in two countries at US #2 and HR #29. android-comics recorded 25 new entries and 92% top-10 retention, making its turnover faster than the category average. New webtoon and unlimited manga-reading entrants are appearing simultaneously across multiple markets. This is the most reliable early signal for editorial planning.

Confidence: High

2. android-watch-face has the highest turnover of any category: 83% top-10 retention and 34 new entries

Watch faces had the lowest top-10 retention among 35 categories at 83%, and the highest number of new entries at 34. New entries include Reddice Classic Analog M1 (HR #3 / US #11), S4U RC ONE (JP #4 / GB #6), perslot7 (US #38 / HR #39 / KR #42), Outdoor - Mountain & Sea (GB #11 / DE #15), PER9 Sport Watch Face Mesa (GB #9), Wave (GB #10), and paid US entries ILLUMINATOR Hybrid-LCD #9 and Digital #10. Top ranks are being replaced in both free and paid charts. Low-priced individual watch faces rotate through the top ranks daily, making this a category worth treating as an ongoing placement opportunity.

Confidence: High

3. AI photo and video generation dominates gains from the 2026-08-30 baseline (US photography grossing #1 and free #1)

Momo: AI Photo & Video Maker simultaneously took US photography grossing #1 (+39) and free #1 (+32). It is followed in the same chart by Hype AI at #3 (+35), Hailuo AI at #5 (+34), and AI Photo Generator-Enhance Pic at #10 (+34). In DE, AI Photo Generator: Muselab AI reached #2 (+43), the largest gain overall; in GB, Vidix-AI reached #7 (+35) in art-and-design. The fact that the same app ranks highly in both free and paid charts matters: this is reaching monetization, not merely generating buzz.

Confidence: High

4. Rotate Rings is a global hit in the top 10 across all six markets (DE #1 / HR #1 / GB #2 / US #2 / JP #3 / KR #6)

The casual game Rotate Rings reached the top 10 in android-game/free across all six markets. It was absent from the DE and HR charts on the 2026-08-30 baseline and is now #1 in both; it rose +30 in JP and +29 in US; and it was absent on the previous date, 2026-09-28, in KR before entering at #6 today. Rather than spreading market by market with time lags, it is taking off almost simultaneously. In android-game, Keyboard Escape: +1 Speed ASMR also reached HR #7 (+27) and entered DE #15 / GB #16. Short-session games built around ASMR and simple controls are leading today’s game category.

Confidence: High

5. Top ranks are not moving; turnover is concentrated in ranks 31–45 (top 94% retained, |Δ| 0.7 / bottom 76% retained, 13% new)

Ranks 1–10 contain 3,256 slots and are almost fixed, with held 94%, new 1%, and average movement of 0.7. Ranks 11–30 are held 89%, new 3%, and |Δ| 2; ranks 31–45 are held 76%, new 13%, and |Δ| 2.7. New entries generally begin at the lower end, then the key question is whether they rise into the middle ranks in subsequent days. Developer values are broadly missing, so this dataset cannot identify which developers dominate top placements; the relevant tier-table fields are also blank.

Confidence: High

6. PDF/document readers rise simultaneously in four markets: DE tools #1, KR tools #1, and a new JP productivity #5

PDFMaster - PDF Reader, absent on the baseline date, is now DE tools #1, while PDF Reader: Viewer, Edit PDF is KR tools #1. Other gains include PDF Reader: Edit HWP, DOC, PPT at KR productivity #12 (+31), Instant PDF Reader at DE business #3 (+31), PDF Kit at JP business #4 (+29), PDF Reader: Documents Master at GB tools #9 (+21), PDF File Reader entering JP productivity at #5, and All Document Reader entering KR tools at #16. Established utility slots are being reshuffled across a broad region, making this worth watching as an ASO-driven, high-volume category.

Confidence: High

7. Multiple Google first-party apps appear across charts on the same day (Contacts across 3 countries × 2 categories; Google Keep at US #29 / GB #39)

Contacts appeared on the same day in both android-communication/free (GB #31 / DE #32 / KR #33) and android-android-wear/free (DE #32 / GB #33 / KR #40), while also reaching HR android-wear #22 (+21). Google Keep was also new at US #29 and GB #39. The simultaneous appearance of first-party apps in multiple charts is more likely related to preinstallation or distribution updates than a shift in user behavior, and should be excluded from trend interpretation.

Confidence: Medium

8. Separation between cross-market hits and local-specific titles: X is news #1 in all six markets, while domestic apps rank highly in DE / HR

The titles in the top 10 across all six markets are familiar, stable apps such as X (news #1 in every market), Duolingo, ChatGPT, Canva, WhatsApp, Spotify, Uber, Tinder, and Instagram. Today’s differences are on the local side: DE has tagesschau as a new news #4, BMW BERLIN-MARATHON 2026 at sports #1 (absent on the baseline), and VVS Mobil #19 (+26). HR has Gdje je tramvaj #8 (+22) and a new Live World Map at #10. In KR paid, 희담필터 #1 and 회독JLPT #2 are new. Local initiatives have distinct winning patterns by market.

Confidence: High

9. KR / GB / US have many new entries, but uneven numbers of comparable charts require caution (only 63 of 76 US charts comparable)

New-entry counts are GB 129, KR 128, US 126, DE 123, JP 110, and HR 105. However, the number of comparable charts varies: US 63/76, GB 50/59, and KR 46/50, so simple comparisons between markets are not valid. top-10 retention is nearly identical across the six markets at 93–95%, with no market-level difference in top-rank stability. To assess which markets are more volatile, use retention and category-level breakdowns rather than new-entry counts.

Confidence: Medium

Recommended Actions

  • Track Mango: Comics & Manga and Toonhub for the next three days to determine whether their HR #5 and US #2 positions hold (= sustained adoption) or fall to the lower ranks (= temporary promotion). If they hold, prioritize a comparative feature on webtoon and unlimited manga-reading apps.
  • Make android-watch-face (83% top-10 retention, 34 new entries) a permanent weekly watchlist category. The actions of developers launching simultaneously in multiple countries, such as S4U RC ONE, Reddice, and perslot7, can help inform content launch timing for Wear OS.
  • Turn the US photography AI-generation app group into a comparison article centered on the overlap between free and paid leaders: Momo at grossing #1 / free #1, Hype AI #3, and Hailuo #5. Add Muselab AI at DE #2 (+43) to frame it as a simultaneous US-European movement.
  • Document the six-market / three-market rollout of Rotate Rings and Keyboard Escape as a case study of dissemination patterns for simple-control casual games. KR is a new #6 today, making it a useful sample for measuring follow-on speed.
  • TOP_GROSSING degradation is widespread (nearly all categories in DE), so defer conclusions based on revenue rankings and first resolve the causes of 32 fetch failures and 31 uncollected charts. DE grossing categories and android-game in US/JP/KR should be the highest recovery priorities.
  • List the 41 charts that could not be compared against the previous day, then re-run new-entry classifications retroactively once they become comparable. Treat today’s new-entry count as an underestimate.
  • Consider filling the 80,363 missing developer values. Until this is addressed, the most useful lens for understanding high-volume app categories—identifying which developers dominate top ranks—will remain unavailable.

Data Quality Notes

For the target date 2026-09-29, 361 charts / 13,438 rows were collected. Of 392 target charts (the configured total excluding 238 whose sources had not yet been published), 31 charts were not collected. Of the 361 charts, 320 could be compared against the previous date, 2026-09-28; the remaining 41 had no previous-day data and could not be classified as “new entries.” Rows in those charts were not counted as new, so the actual number of new entries may be higher than reported here. Of recent runs, 6 completed partially and 32 fetches failed. Degraded sources affect 100 charts, especially TOP_GROSSING (nearly all grossing categories in DE, grossing for major categories in KR/US/GB/HR, and all android-game charts in US/JP/KR). Therefore, conclusions based on paid rankings—particularly DE and US/KR game and tools grossing—have weak support. Attribute gaps are also substantial: developer is missing for 80,363 records, ratingCount for 80,363, and rating for 1,536. As a result, the tier table’s “developers occupying top slots” fields are blank, and developer-level concentration analysis cannot be performed today. The baseline date, 2026-08-30, is the oldest collection date in the archive. Although nominally 30 days ago, a full month of history does not exist; therefore, interpret “monthly rises” not as strict month-over-month changes, but as differences across the longest available interval.
