Google Play vs App Store top charts API

A Google Play vs App Store top charts API comparison on Trends MCP means two get_top_trends calls: type Google Play and type App Store Top Free. From the August 13, 2026 scans, Google Play ranked WhatsApp Messenger #1 while App Store Top Free ranked 7 Brew Coffee #1 and ChatGPT #3. Only a handful of brands, including ChatGPT, Google Gemini, WhatsApp Messenger, and TikTok, appear near the top of both lists on the same day. Follow with app downloads by Android bundle ID and google search on brand names when absolute demand matters more than chart position.

What Google Play and App Store chart data shows right now

From the Trends MCP scans of August 13, 2026 (Google Play as_of 04:01 UTC; App Store Top Free as_of 02:01 UTC), the top 12 rows on each board:

Cross-store overlap in the top 25 on that pull: ChatGPT (Play #11, iOS free #3), Google Gemini (Play #22, iOS free #12), WhatsApp Messenger (Play #1, iOS free #18), TikTok - Videos, Shop & LIVE (Play #8, iOS free #22). Most other top rows were store-specific: Free Fire and Flipkart on Play; 7 Brew Coffee, ParentSquare, and ClassDojo on iOS free.

Growth follow-ups on the same day (Trends MCP API, August 13, 2026):

Chart rank and install volume often diverge. WhatsApp held Google Play #1 while 30-day Android download volume for com.whatsapp fell 84.23% from the July 12, 2026 baseline. That is why a two-board page still needs download and search follow-ups.

Exact API calls for both charts

Two board calls cover the cross-store snapshot. Each get_top_trends request costs one request against the monthly quota. A third call on app downloads or google search answers whether a shared title is still gaining installs or search interest.

}

Join on normalized brand names, not raw titles. Play returns ChatGPT while iOS free returns the same string; Play returns TikTok - Videos, Shop & LIVE while iOS also lists TikTok Pro - Events, which is a different product and should not be joined.

How the two boards differ in practice

Google Play ranks on August 13, 2026 were dominated by messaging, video, and games: WhatsApp, Facebook, YouTube, Instagram, Free Fire. App Store Top Free mixed regional utilities and commerce: 7 Brew Coffee #1, ParentSquare #4, ClassDojo #6, Temu #10, Depop #11. AI clients sat higher on iOS free (ChatGPT #3, Claude by Anthropic #13, Google Gemini #12) than on Play (ChatGPT #11, Google Gemini #22).

History depth differs by follow-up source. app downloads returned 169 points for com.whatsapp and 176 for com.zhiliaoapp.musically on the August 13, 2026 pull. Google Search returned 261 points for ChatGPT and WhatsApp. Neither chart board itself stores multi-year rank history in get_top_trends; the board is a live snapshot with an as_of stamp.

Who uses a dual-chart pull

ASO teams compare whether a launch day spike is iOS-only or also visible on Play. Marketplace operators watch Temu, Vinted, and Depop on iOS free while Play stays heavy on Flipkart and social apps. Game marketers treat Free Fire at Play #5 plus a +10.71% 30-day YouTube index as a stronger signal than an iOS free absence. AI product teams track ChatGPT on both boards and Claude on iOS free when Play has no matching title in the top 25.

A practical loop on August 13, 2026 data: pull both boards (2 requests), list titles in the top 25 of both stores (4 brands above), then spend 3 to 5 get_growth requests on bundle IDs and brand search. That stays inside the free tier's 100 requests per month for a daily job.

Limits and honest caveats

Display names are not bundle IDs. Android download follow-ups require the Play package name (com.whatsapp, com.roblox.client). iOS-only hits such as 7 Brew Coffee and ParentSquare often have no Android series; say so instead of inventing a package. Recent download weeks can print 0.0 volume for some titles even when the chart still lists them, as seen for com.dts.freefireth on 2026-08-13; quote the baseline week and flag the zero rather than computing a fake rate.

Google Search briefly returned data_unavailable for Temu during this run, so Temu search growth is omitted. Prefer the chart ranks plus any source that succeeds on retry. Zero-baseline download windows can return 999999% growth; quote absolute recent volume instead of that percent.

Pricing for dual-store chart monitoring

Free covers 100 requests per month. Starter is $19 for 1,000 requests, Pro $49 for 5,000, Business $199 for 25,000. Annual billing saves 20%. Check current pricing on the site before budgeting. Two board pulls per day for a month use about 60 requests, leaving headroom for growth follow-ups on the free plan.
