Track Android chart rank position over time with the app rankings source. Pass the Play package name, not the display title, and read rank volume plus a 0-100 index.
Live data as of 2026-08-13
An Android app rankings API on Trends MCP is the app rankings source on get_growth and get_time_series. The keyword must be an Android bundle ID. On August 12, 2026, com.openai.chatgpt held chart volume 1.0 with index 100.0 over 30 days (flat vs July 14, 2026), while com.whatsapp sat at volume 2.0 with index 95.8 (+4.47% index over 30 days). Pair the live Google Play board for discovery; use rankings for position history and app downloads for install volume.

For com.roblox.client, the 30D index baseline was 0.0 on 2026-07-14, so the API returned 999999% index growth. Quote the rank volumes (3.0 to 2.0) instead of that percent.
Discovery stays on the board. History stays on app rankings. Installs stay on app downloads. Three shapes cover the loop.

Rank position and install volume answer different questions. On August 11 to 12, 2026, WhatsApp held Play board #1 and rankings volume 2.0, yet app downloads for com.whatsapp showed 3,369,352 recent volume against 21,365,177 on the 30-day baseline (-84.23%). TikTok rankings volume stayed at 4.0 over 30 days while downloads fell from 12,624,137 to 1,944,671 (-84.60%). Gemini rankings volume worsened from 10 to 23 (+130% rank volume, meaning a worse chart slot) while the index fell 72.25% over 30 days.
Use rankings when the question is "where does this package sit on the chart." Use downloads when the question is "how many installs moved." Use both before calling a chart climb a growth story.
ASO analysts watch whether a feature release moves rank volume inside 7 or 14 days. Competitive intel teams compare ChatGPT at volume 1.0 against Gemini at 23.0 on the same recent_date. Portfolio managers watching consumer internet names treat Spotify's move from rank 45.0 to 39.0 over 30 days (+24.93% index) as a softer signal than install estimates alone. Automation jobs store daily get_growth rows for a fixed bundle list and alert when 7D rank volume rises (worse) or falls (better) by more than 20%.
History is short. Several packages begin on 2026-07-14, so 3M, 6M, and 12M presets returned date_out_of_range on August 13, 2026. Time series can emit multiple rows per calendar day with different volume values for the same bundle; treat that as multi-chart coverage and confirm which chart your product cares about before graphing. Zero baselines produce 999999% index jumps. Missing packages return no_data rather than a guessed rank.
There is no get_top_trends type named app rankings. The live list remains Google Play. This page covers keyword growth and series for packages you already know.
Free includes 100 requests per month. Starter is $19 for 1,000, Pro $49 for 5,000, Business $199 for 25,000. Annual billing saves 20%. Check current pricing before locking a budget. A daily job that pulls rankings growth for 10 bundles uses about 300 requests per month and needs Starter or higher.
