KEN’S CAT LOG

Daily Google Play Report 2026-09-18

Today's biggest signal is the effective reshuffling of HR's android-sports charts (52 new entries; 86% top-10 retention), with BeSoccer debuting directly at #1. In addition, DAVE THE DIVER entered paid games in multiple countries on the same day at KR #1 / US #7, while Themely landed simultaneously in personalization across DE/GB/HR.

1. New arrivals

Titles entering multiple countries on the same day are the strongest signal. DAVE THE DIVER debuted simultaneously at #1 in KR's android-game/paid chart and #7 in the US (agg:arrival/com.mintrocket.drmobile/android-game/TOP_PAID). Taking the top spot in a paid chart on day one is rare, making this today's most newsworthy move. Themely - Icons & Widgets landed simultaneously in personalization/free across three countries: DE #40 / GB #41 / HR #41. Other two-country arrivals include Giggles: Videos & Trends (HR #11, DE #26), Yalla Shoot (HR #17, DE #38), PDF Converter: Editor & Reader (GB #26, DE #38), and Vimex (GB and US, both #35). In individual markets, HR's android-sports chart was extraordinary: BeSoccer #1, Football Live Score: Soccer #4, Live Cricket TV HD #5, and LiveScore #6 all arrived at once. In KR, Tasker entered paid at #2 and Clean My Files entered free at #8.

2. Risers over the period

The baseline date is 2026-08-26. This is the oldest date in the archive and only 23 days before today, so it should not be treated as a full month. The largest gain was Gambonanza in US paid games at #2 (+40), followed by Splitwise in HR grossing at #5 (+38), CHARGESPOT in JP at #4 (+37), and TradingView in HR grossing at #1 (+36). Among apps absent from the baseline that entered today's top 20, GB's Seneca at education #1, JP's エアウォレット at finance #1, and KR's DAVE THE DIVER at paid #1 stand out. GB education also saw school-focused apps rise together: Tapestry #5 (+31), Seesaw #6 (+23), and Canvas #12 (+22), a pattern consistent with back-to-school demand.

3. Tier-level trends

The head is stable; the tail moves. The top tier (ranks 1–10) was nearly unchanged, with 96% held, 1% new, and an average movement of 0.4. The mid tier (ranks 11–30) had 93% held and |Δ| of 1.3. Only the bottom tier (ranks 31–45) served as a meaningful entry point, with 84% held, 10% new, and |Δ| of 1.9. Most of today's arrivals appearing in the 30s and 40s fits this structure. Developer information is missing, so the developers dominating top slots cannot be identified from today's data.

4. Country-level trends

HR had the most new arrivals (125; 94% top-10 retention), concentrated in sports and personalization. It was followed by US with 79, DE with 71, and GB with 65. JP (53; 97%) and KR (53; 94%) had fewer entries, but KR saw more turnover at the top. DE was the most stable, with 98% top-10 retention. The shared leaders are established apps: Canva, Spotify, ChatGPT, X, and Facer are top-10 in all six markets. In contrast, HR's sports-streaming apps, KR's paid games, and JP's CHARGESPOT/詐欺バスター Lite are entirely local movements.

5. Category-level trends

The two categories that turned over were android-sports (52 new entries; 86% top-10 retention) and android-personalization (35; 85%), both at the bottom of all categories for retention. They were followed by android-game (29), android-tools (19), android-education (16), and android-health-and-fitness (16). By contrast, android-business and android-house-and-home had 100% top-10 retention, while android-comics was nearly static with only two new entries. AI-related apps (AI Catch, AI Video, Couple AI, and Design Home) continue to emerge in the lower tiers of art-and-design, photography, and video-players—a cross-category market condition worth tracking.

Key findings

1. DAVE THE DIVER debuted at KR paid games #1 and US #7 on the same day

Absent on 2026-09-17, it entered today's android-game/TOP_PAID chart simultaneously at #1 in KR and #7 in the US. A day-one #1 in a paid chart is rare, and appearing in two markets at once is a stronger signal than an isolated debut. KR also saw Batomon Showdown newly enter paid at #14, indicating broad movement in Korean paid games today.

Confidence: High

2. HR's android-sports effectively reshuffled — BeSoccer debuted directly at #1

android-sports was the most volatile of all 35 categories, with 52 new entries and 86% top-10 retention, most of them concentrated in HR. BeSoccer #1, Football Live Score: Soccer #4, Live Cricket TV HD #5, LiveScore #6, YACINE TV #9, and Yacine TV #10 filled the upper ranks despite being absent in the previous snapshot. Live scores and free sports streaming gained exposure across HR all at once, suggesting there is still room for similar apps to enter.

Confidence: High

3. Themely landed across DE/GB/HR personalization simultaneously; category retention hit a low of 85%

Themely - Icons & Widgets entered android-personalization/free on the same day in three markets: DE #40, GB #41, and HR #41. android-personalization had the lowest category retention, with 35 new entries and 85% top-10 retention. In HR, Photo Lock App #9 and Candy Race Launcher #10 also entered high in the chart. Icons, widgets, and lock-screen apps all turned over today, making this an area with strong near-term traction for new concepts.

Confidence: High

4. PDF/document readers are rising across all markets — new arrivals, major gains, and global top-10 placement

PDF Reader, PDF Viewer is in the productivity/free top 10 across all six markets: KR #1, GB #2, HR #2, US #3, DE #4, and JP #7; in the US it rose +22 versus the baseline. In KR, PDF Reader & Viewer: Edit PDF is #12 (+31), and All Document Reader is #15 (+10) in android-tools. In the US, All PDF Reader & PDF Editor is #31 (+12). Meanwhile, PDF Converter: Editor & Reader newly entered at GB #26 and DE #38, showing that fresh inflow is continuing. This is currently the deepest demand segment among general-purpose utilities.

Confidence: High

5. The largest period gain was US paid-game Gambonanza at +40 (#2); the baseline is 23 days old

The largest rank gain since the 2026-08-26 baseline was Gambonanza, up +40 to #2 in US android-game/paid. It was followed by Splitwise at HR finance/grossing #5 (+38), CHARGESPOT at JP lifestyle #4 (+37), and TradingView at HR finance/grossing #1 (+36). However, the baseline is only 23 days old and is the archive's oldest collection date, so treating this as a monthly change would overstate it. In HR finance/grossing, Splitwise, TradingView, Kraken, and Investing.com all rose together, which may indicate a market-level structural shift.

Confidence: Medium

6. School platforms rose together in GB education (a back-to-school pattern)

Tapestry Education Platform #5 (+31), Seesaw #6 (+23), and Canvas By Instructure #12 (+22) all rose from the baseline, while Seneca - AP & Test Prep went from absent to #1. In HR, Photomath #1 and Google Classroom #2 also entered high after being absent from the baseline. android-education showed movement overall, with 16 new entries and 95% top-10 retention, consistent with the start-of-term demand pattern. This is a timely window for learning and parent-focused products.

Confidence: High

7. The top is immobile; new apps enter from rank 31 downward — 96% retention at the head, 10% new in the tail

the top tier (ranks 1–10) was almost frozen, with 96% held, 1% new, and an average movement of 0.4. The mid tier (ranks 11–30) had 93% held and |Δ| of 1.3. Only the bottom tier (ranks 31–45) had 84% held, 10% new, and |Δ| of 1.9. Most same-day multi-market entries (Themely, Vimex, Timestamp Camera, Flightsky, and others) appeared in the 30s and 40s, matching this structure. A new title's initial target should be reaching the bottom tier; plans should assume the top 10 will not move on a daily basis. Developer data is missing, so today's data cannot determine whether a small group of developers dominates top slots.

Confidence: High

8. Market differences: HR/US are turnover markets, DE/JP are stable, and KR moves at the top

HR led by a wide margin with 125 new arrivals, followed by US 79, DE 71, GB 65, JP 53, and KR 53. By top-10 retention, DE at 98%, GB at 97%, and JP at 97% were stable, while HR and KR at 94% were the most active. KR's lower retention despite fewer new entries indicates that its changes occurred near the top (DAVE THE DIVER paid #1, Tasker paid #2, Clean My Files #8, and Limbus Company grossing #20). Use HR for entry testing, KR when top-rank outcomes matter, and DE for stable shelf placement.

Confidence: High

9. AI-generation apps continue flowing into lower tiers of art-and-design, photography, and video-players

In DE, AI Catch: AI Video Generator reached #30 (+15); in KR, Shots - AI Photo & Video Maker reached #20 (+20); in the US, Framly reached #30 (+12); and CineSpark AI reached US video-players/grossing #22 (+11). New entries also continue: Couple AI (GB #26), Design Home - AI Home Makeover (GB #38 and US #45 simultaneously), AI Video - AI Video Generator (KR photography grossing #35/free #40), and Pollo AI (DE #38). Individual apps may have uncertain longevity, but supply and demand for the genre continue.

Confidence: Medium

10. Static categories: business and house-and-home retained 100% of the top 10; comics had just two new entries

android-business (11 charts, 6 new entries, 100% top-10 retention) and android-house-and-home (7 charts, 10 new entries, 100% retention) saw no movement at the top today. android-comics was effectively stopped, with two new entries and 97% retention. In business, Microsoft Teams occupies the top 10 in every market: #1 in DE/GB/HR/US, #4 in JP, and #10 in KR. This is not a space where daily reshuffling should be expected. Conversely, new concepts entering these categories cannot be evaluated through daily signals alone; different metrics are required.

Confidence: High

Recommended actions

  • HR's android-sports chart nearly reshuffled today (52 new entries; 86% top-10 retention). If you have a live-score or free sports-streaming concept, launch in HR first and move this week. Track how long BeSoccer #1 and LiveScore #6 hold in daily data from tomorrow onward, and determine within 2–3 days whether this is temporary or durable.
  • DAVE THE DIVER's KR #1 / US #7 is one of the few meaningful paid-game movements, so its position must be tracked tomorrow. If the day-one lead holds in following days, it would suggest that Korean paid games currently have low exposure costs—a window for new entrants.
  • personalization (35 new entries; 85% top-10 retention) is seeing daily turnover in icons, widgets, and lock-screen apps, making it ideal for short-cycle themes and widget concepts. Use Themely's simultaneous three-market entry (around #40 in DE/GB/HR) as a reference and set reaching the bottom tier (ranks 31–45) as the initial KPI.
  • PDF/document readers are top-10 in all six markets (PDF Reader, PDF Viewer: KR #1 through JP #7), with new arrivals continuing. If building one general-purpose utility, this is the segment. Competition is dense, however, so decide the differentiation axis first—scanning, conversion, or annotation.
  • GB education (Tapestry +31 / Seesaw +23 / Canvas +22 / Seneca #1) shows a back-to-school demand pattern. Parent- and school-focused concepts need to launch this month or the window will be missed. JP's Think!Think! and HR's Photomath/Google Classroom show the same movement, working across multiple markets at once.
  • Do not make monetization-revenue (TOP_GROSSING) decisions from today's data. DE is degraded across nearly all categories, and GB across a broad range. HR finance/grossing (TradingView #1, Splitwise #5) looks promising and can be used in isolation because HR finance/grossing is not on the degraded list, but do not use it for cross-market comparisons.
  • Given the tier behavior (96% top retention; 10% new in the bottom), split daily-report alert thresholds by tier. Only 1% turnover occurs in the top 10, so any new arrival there is worth unconditional escalation.
  • developer and ratingCount are missing in 93,021 records, so developer-level concentration analysis and review-count-based evaluation cannot be performed today. Prioritize checking the app-detail retrieval stage of the collection pipeline so the developers column in the tier table is populated in future daily reports.

Data quality notes

Today, 356 charts and 13,259 rows were collected. Of the 388 charts configured for collection (excluding 242 not published by the source), 32 were not collected; among recent runs, 6 completed partially and 36 fetches failed. Of the 356 charts, 329 could be compared with 2026-09-17. The remaining 27 lacked a previous snapshot, so they are not “unchanged” but “not comparable.” Rows from charts without a previous snapshot were not counted as new arrivals, so this report's new-entry counts are biased downward. Degraded sources are heavily concentrated in TOP_GROSSING: DE spans nearly all categories' TOP_GROSSING, GB has broad TOP_GROSSING and TOP_PAID degradation, and US/JP/KR/HR are also affected in many places. Therefore, rankings and new entries related to monetization revenue should not be interpreted across markets. For attributes, developer is missing in 93,021 records, ratingCount in 93,021, and rating in 4,544; consequently, developer concentration (the tier table's “developers holding most slots” field is “—”) and rating-score-based analysis cannot be performed today. The monthly baseline date of 2026-08-26 is 23 days before today and the archive's oldest collection date, so it cannot be treated as a full month of change.
