What Is Astro?

Astro is a native macOS application for iOS developers who want to do App Store keyword research without an enterprise subscription. Its reputation among indie developers comes from three things: the price ($9 a month, billed as $108 a year, for one Mac license with no per-keyword fees), the interface (it feels like a Mac app because it is one), and the popularity data, which it reads from Apple Search Ads rather than estimating. For a keyword you get popularity, a difficulty score for the top-10, daily rank history, related suggestions, and a side-by-side look at how competing apps use the term in their metadata. It covers more than 60 storefronts and can translate keyword lists through DeepL.

Its boundaries are equally clear. Astro is App Store only: no Google Play. It runs only on macOS 14 and later. It does not write listings, generate screenshots, monitor competitors' metadata changes, or publish anything; you take its research to App Store Connect yourself. There is no free plan, only a 14-day refund window. Its site claims that 90% of users see more impressions within a week; treat that as the vendor's number.

What Is AppDrift?

AppDrift is a browser-based ASO platform for indie developers and small studios covering both stores: keyword tracking with a 0-100 difficulty score beside every term, AI metadata generation that regenerates until the copy fits Apple's and Google's limits, translation into 60+ languages on live per-market keyword research, a free screenshot generator, store monitoring with alerts, a weekly action plan, and one-click publishing.

For an iOS developer the most relevant AppDrift feature is Apple Search Performance. Since August 2026, paid plans sync App Store Connect Analytics daily and show impressions, tap-through rate, conversion rate, retention cohorts and revenue per acquisition search term for your own app, joined to your tracked ranks. Astro's Apple Search Ads popularity tells you how much a term is searched; App Store Connect tells you how many of those searches became your installs. Both are Apple numbers; only one is about your app.

AppDrift's limits: AI actions are metered in tokens (500 a month on Basic, 3,000 on Pro, 8,000 on Studio; a full generation costs 7 tokens per language on iOS). Tracked keywords are capped at 5 on Free, 50 on Basic, 500 on Pro and 1,500 on Studio, against Astro's unlimited. Competitor rank tracking is a Studio feature. Google Play rank checks see roughly the top 30 results. There is no native Mac app and no Apple Search Ads campaign management.

Features Compared

Keyword research

Astro is the deeper research tool for the App Store specifically: unlimited keywords, Apple Search Ads popularity, and competitor keyword extraction in a fast native interface. AppDrift's research is built into the workflow: its difficulty and popularity scores are the same ones behind the free keyword difficulty checker, its Keyword Ideas panel pulls live autocomplete from each storefront, and the keywords it finds flow straight into the title and subtitle it writes. If you want to spend an afternoon exploring a category on iOS, Astro. If you want the research to end in a shipped listing, AppDrift.

Apple data

This is the real dividing line for iOS developers in 2026. Astro's popularity is a demand-side estimate from Apple Search Ads. AppDrift's Apple Search Performance is Apple's own supply-side measurement of your app: which search terms produced impressions, taps, installs, retained users and revenue. Apple shipped that data in July 2026; AppDrift syncs it daily; Astro does not read it. Both tools compute difficulty themselves, because Apple does not publish one.

Writing, localization, screenshots, publishing

Astro suggests keywords and translates keyword lists. AppDrift writes the listing (title, subtitle, keyword field, description, promotional text, release notes), translates the whole listing into 60+ languages with per-market keyword research, makes the screenshots for every device size for free, and pushes the result to App Store Connect and Google Play through your own credentials. When we scored 123 real listings, 94% graded D on localization; that is the part of the job a research app leaves entirely to you.

Platform and stores

Astro is Mac-only and App Store-only. AppDrift runs anywhere with a browser and covers Google Play, with the honest caveat that Play rank checks are capped near the top 30 by the public Play surface. A developer on Windows or Linux, or one with an Android build, cannot use Astro at all.

Pricing Compared

Plan	Astro	AppDrift
Free	None (14-day refund)	1 app, 5 keywords forever, 50 AI tokens, screenshots, ASO score
About $9	$9/month billed annually ($108/year), unlimited keywords, one Mac	Basic $9.99/month ($99/year): 5 apps, 50 keywords, 500 tokens, every paid feature
$19.99	-	Pro: 20 apps, 500 keywords, 3,000 tokens
$39.99	-	Studio: 50 apps, 1,500 keywords, 8,000 tokens, competitor rank tracking

Per year the two entry plans are $108 and $99. Astro's buys unlimited App Store research on a Mac. AppDrift's buys 50 tracked keywords on both stores plus generation, translation, screenshots, monitoring, publishing and Apple's per-keyword data. The right question is not which is cheaper but which half of the job you are paying to remove.

Who Should Pick Which

Pick Astro if

You ship only on the App Store and work on a Mac
You want unlimited keyword research with Apple Search Ads popularity for $9
You write and submit your own metadata and prefer a native app to a web dashboard
You do not need Google Play, screenshots or publishing

Pick AppDrift if

You publish on both stores, or on any OS other than macOS
You want the listing written and translated, not just researched
You want Apple's real per-keyword impressions and conversion for your app next to your ranks
You want free screenshots and alerts when something changes
You want a free plan to start and an API or MCP server for automation

Can You Use Both?

Yes, and for an iOS-first developer it is a good pairing at about $19 a month: Astro for wide keyword exploration on the Mac, AppDrift to write, translate, screenshot and publish the result and to read Apple's conversion numbers on the keywords you chose. AppDrift's free plan alone covers the second half for one app with five tracked keywords.
