App Store Charts — Daily Rank Movement

Track App Store Top Free and Top Paid charts by country — and see exactly which apps moved since your last run: rank change, direction, new entries and drop-outs.

Apple's official free RSS feed. No API key, no login, no anti-bot.

Why this one

A chart snapshot is a commodity — anyone can fetch today's top 50. The value is the delta: "Duolingo jumped +14 places in US Top Free overnight", "3 new entries in Finance", "this app fell out of the top 100 entirely". Schedule it daily and every row carries its movement, so you get the signal ASO teams and app-focused investors actually act on.

What you get

Field	Description
rank / previousRank	Position now, and last run
rankChange	Places gained (+) or lost (−) since the last run
signal	surging (+10 or more) · rising · stable · falling · plunging · new_entry · dropped_out
direction	up · down · flat · new · dropped_out
isNewEntry	First time this app appears in the chart
appName / developer / genre / genres	App identity and category
country / chartLabel	Which store and which chart
appId / appUrl / artwork / releaseDate	Identifiers and links

How to use it

1. Pick countries (us, gb, de, pk…) and charts (Top Free / Top Paid), and a depth up to 200.
2. Schedule it daily — the first run sets the baseline, and every run after that reports movement.
3. Tick Only apps that moved for a clean alert feed, and wire a webhook.

First run has no baseline, so everything comes back as new_entry. That's expected — run it again tomorrow to see real movement.

Typical uses

• ASO / marketing — prove a launch or campaign moved the chart, and watch competitors climb.
• App investing / alt-data — chart velocity is a cheap public proxy for download momentum.
• Category scouting — spot new entries breaking into a genre early.
• Competitive alerting — schedule with moversOnly + a webhook and get pinged only on real moves.

Pricing

$1.00 / 1,000 rows ($0.001 per result), plus a near-zero start fee. Never charged beyond your maxItems; failed charts are reported in QUALITY_REPORT, not billed as data.

FAQ & limitations

• Where does the data come from? Apple's official RSS Marketing Tools feed — public and free.
• Why is everything new_entry on run 1? There's no previous snapshot yet. The baseline is stored in the key-value store (RANK_SNAPSHOTS) and used on the next run.
• Does it give download numbers? No. Public chart rank only — no vendor publishes true downloads for free. Rank movement is the honest proxy, and it's labelled as such.
• Google Play? Not yet — Apple's feed is the one with a clean, official, unauthenticated source.
• How deep can it go? Up to 200 ranks per chart per country.
• Grossing charts? Apple's v2 apps feed exposes Top Free and Top Paid; grossing isn't offered there.
