Daily Google Play Report 2026-10-09

AI-powered home design is growing across multiple markets at the same time. In GB, Room Design AI is up 39 spots from the baseline date of 2026-09-09 to #4, RoomGPT AI is newly ranked at #10, and in the US, Designest is up 29 spots to #8. Among apps that appeared simultaneously in multiple countries, Shasha (DE #8, US #35) is the strongest and could be a content topic.

New Entries

There were 20 apps that appeared simultaneously in multiple countries since the previous report on 2026-10-08. The strongest was the entertainment app Shasha, at #8 in DE and #35 in the US. Most of the others entered the lower ranks, between #31 and #45. By genre, watch faces (Digital Informer: DE #18 and US #44, Watch Face CUE Indus, Lihtnes Watch Face 001), video-to-audio conversion (MP3 Converter, Video to MP3), and AI video generation (AI Music Video Maker - Rap AI: US #31 and GB #33, Lumy) stood out. Among the top entries in single-country charts were GIMP at #1 and Knot IQ at #3 in US paid charts, plus Moj at #7, Bigo Live at #8, and ShareChat at #10 in HR social.

Sharp Monthly Rises (Baseline Date: 2026-09-09, 30 Days Earlier)

The baseline date is the earliest collection date in the archive, so a full month of data is not yet available. The largest gain was iOS Control Center - Panel in DE (+40 to #2), followed by Room Design AI in GB (+39 to #4) and AOK Ident in DE (+37 to #3). In AI image and video, Hailuo AI (+31 to #7) and Vidix (+31 to #12) rose in DE, while the seasonal app Autumn Vibes gained traction in the US (+30 to #11). Many apps that were absent on the baseline date also reached #1 this time, including 도깨비의세계 (free #1) and FreeReels (#1) in KR.

Trends by Tier

The top tier (ranks 1–10) is largely fixed, with 87% held, 1% new, and |Δ| of 1.4. The middle tier (11–30) has 79% held and |Δ| of 3.6. The lower tier (31–45) has 61% held, 24% new, and |Δ| of 4.7, with turnover concentrated there. Because developer information is missing, it is not possible to determine whether specific developers dominate the top ranks.

Trends by Country

The US had the most new entries with 171, followed by HR with 150 and KR with 127. DE had the highest top-10 retention rate at 89%, while GB had the lowest at 86%. Apps shared across multiple countries include ChatGPT (ranked #1 in DE, GB, HR, and JP; #2 in KR and the US), Claude by Anthropic (#3 in KR and the US, #4 in DE, GB, and JP, and #10 in HR), CapCut, and Canva. In contrast, the concentration of new entries in HR social is specific to HR.

Trends by Category

The category with the most turnover was android-social, with 52 new entries and an 80% top-10 retention rate. It was followed by android-tools (43 entries, 81%) and android-game (42 entries, 77%). By contrast, android-libraries-and-demo (0 entries, 100%), android-maps-and-navigation (98%), and android-comics (96%) saw almost no movement. Both android-watch-face and android-photography had top-10 retention rates of 76%, indicating turnover even at the top.

Key Findings

Recommended Actions

  • Make a comparison of AI interior design apps (Room Design AI: GB #4, RoomGPT AI: GB #10, Designest: US #8) today's top priority.
  • Track whether Shasha (DE #8, US #35) remains on both markets' charts tomorrow; if it does, turn it into a feature article.
  • Create a seasonal roundup of autumn and Halloween watch faces (Autumn Vibes: US #11, Happy Halloween Watch Face: US #22).
  • Write a short cross-market article comparing the blood pressure and blood sugar management apps gaining traction in DE, the US, and JP.
  • Confirm with the following day's data whether the concentration of new entries in HR social reflects real demand or chart-side reordering before covering it.
  • Report TOP_GROSSING collection failures, especially for HR, DE, and the US, to the collection team, and note that revenue analysis is incomplete.

Data Quality Notes

Of 341 target charts, 236 charts (8,978 rows) were collected, while 105 charts could not be retrieved. Of the 236, 213 charts could be compared with the previous report on 2026-10-08. Rows from charts that did not exist in the previous report were not counted as new entries. Six recent runs completed only partially, with 34 collection failures. TOP_GROSSING data is particularly incomplete: comparisons of paid revenue are limited in nearly all HR categories and in many categories in DE and the US. GB, JP, and KR also have many missing TOP_PAID charts. developer and ratingCount are missing for 75,867 records, so developer concentration by tier cannot be assessed. The monthly baseline date, 2026-09-09, is the earliest collection date in the archive, and a full month of data is not yet available.
