> Disclosure: We build Sonar (trysonar.app), so weigh this accordingly. This guide is not a ranking. Each tool below gets the job it does best, there's a section on when to stay with Astro, and Sonar's own limits are spelled out next to its strengths. Competitor prices were checked on each vendor's pricing page on October 19, 2026.
What Is Astro ASO?
Astro ASO is a macOS-native keyword research and rank tracking tool for the iOS App Store, sold as a single-Mac subscription at $9/month billed annually — $108/year (source: tryastro.app). It became a default starting point for indie iOS developers thanks to a polished native interface, unlimited keywords and one of the lowest prices in the category. I used Astro for over a year for my own apps before building Sonar. You type a keyword, and the app returns Apple Search Ads popularity, related suggestions and how competing apps use that term — without leaving a Mac app.
Most people looking for an alternative want one of three things Astro doesn't do: Google Play data, access from something other than one Mac, or keyword data they can pull into scripts and AI agents. If none of those apply to you, Astro is probably still the right tool — see when to stay with Astro. If you are early in your ASO journey, our indie developer ASO guide covers the fundamentals first.
Astro ASO at a glance
Short answer: Astro ASO is a $108/year macOS app for iOS keyword research and daily rank tracking, with popularity taken directly from Apple Search Ads. It's strong for Mac-based iOS developers, but it has no Google Play data, no web or Windows version, no public API or CLI, and it records ranks only while the Mac app runs. It does ship an official MCP server, in beta, that works locally on the same Mac (sources: tryastro.app and its docs, checked October 19, 2026).

Astro ASO pricing
As of October 19, 2026, Astro sells one plan: a Single Mac License at $9/month, billed annually as $108 (source: tryastro.app). There are no tiers to outgrow: no keyword metering, no app cap. Prices are in USD with tax added where it applies, and billing runs through Lemon Squeezy, which generates invoices with your company details.
| Billing detail | Astro Single Mac License |
|---|---|
| Price | $108/year, shown as $9/month; the pricing page offers no month-to-month option |
| What's metered | Nothing — unlimited keywords |
| Seats | One license, active on one Mac at a time |
| Free version | Up to 10 keywords (source: Astro docs) |
| Refunds | 14 days to request one after the subscription activates |
What the $108 doesn't cover
The sticker price is honest, but four things sit outside it:
- Annual only. The $9 figure is the yearly price divided by twelve. You pay $108 up front, with the 14-day refund window as the safety net.
- One Mac per license. A laptop plus a desktop, or a teammate, means another license.
- iOS only. There is no Google Play data at any price, so if you ship on Android the real cost is $108 plus a second tool.
- Automation stops at your Mac. There is no public API or CLI. Astro's MCP server (beta) lets an AI assistant on the same Mac read and edit your keywords while the app is open, but nothing outside that Mac can reach your data.
Astro's price against the alternatives
Entry prices from each vendor's public pricing page, checked October 19, 2026:
| Tool | Entry price | Billed yearly | Keywords at entry | Platform | API / CLI / MCP |
|---|---|---|---|---|---|
| Astro | $9/mo | $108/year (annual only) | Unlimited | macOS app, iOS data | Local MCP only (beta) |
| AppSprint Pro | $108/year | $108/year | Not published | macOS app, iOS | Local MCP (38 tools) |
| Mobile Action Lite | $15/mo | $12.50/mo | 100 | Web | API and MCP on a separate, sales-priced plan |
| Sonar Indie | $29/mo | $290/year | 2,500 | Web | All three included |
| ASO.dev Indie | $39/seat/mo | $29/mo | Unlimited tracking list | Desktop apps, App Store keyword data | Local MCP; API in alpha on Pro |
| ASOMobile Indie | $59/mo | $47/mo | 500 | Web | 1,000 API credits |
| App Radar Essentials | €69/mo | €58/mo | 500 | Web | €199/mo add-on or Enterprise |
| AppTweak Essential | $99/mo | $79/mo | 500 | Web | Separate API plan from $166/mo, MCP included |
| Appfigures Optimize | $149.99/mo | $119.99/mo | 500 | Web | Hosted MCP + API on every account; other apps' data uses credits |
A full year of Astro costs about what one to two months of ASOMobile, App Radar or AppTweak cost at their month-to-month rates. What the higher prices buy is web access, Google Play coverage, seats and, in most cases, some way to get the data out programmatically. If you only need a Mac and iOS, only AppSprint matches Astro's price.
When to stay with Astro
I'd rather say this plainly than bury it: for a specific profile, Astro beats every tool on this page, Sonar included.
- You ship only on iOS and work on one Mac. Astro is built for exactly that, and it's the cheapest serious option at $108/year.
- You want unlimited keywords. Sonar's Indie plan caps at 2,500 keywords and 10 apps; Astro has no cap at all.
- You want your data stored locally. Astro keeps everything in a file on your Mac. Sonar and the other web tools keep it on their servers.
- You open the app most days anyway. If Astro is part of your daily routine, the open-app tracking limitation rarely bites.
- A local MCP server is all the automation you need. If your agent runs on the same Mac, Astro's beta server covers reading and editing your keywords.
Astro stops fitting the moment one of those breaks: an Android build, a Windows or Linux machine, a teammate, a pipeline or remote agent that needs the data, or a rank history that can't have gaps.
Why Developers Search for an Astro ASO Alternative
Four constraints push Astro users to look elsewhere: it only runs on macOS, it only covers the App Store, it collects rankings inside its Mac app, and it has no public API or CLI — its MCP server (beta) answers only on the Mac running the app (sources: tryastro.app, tryastro.app/docs/mcp).
Two smaller ones come up too. Astro's keyword suggestions come from keywords other Astro users track, and its docs note they can be few or nonexistent for niche apps and less popular countries (source: tryastro.app/docs/how-to-add-keywords). And because the history lives in a single-license desktop app, there's no web dashboard to share with a teammate or client.
How we evaluated
I compared each tool on what makes people leave Astro: store coverage, where it runs, how ranks get recorded, how you get data out (API, CLI, MCP) and what it costs at the entry tier. Prices and plan limits come from each vendor's own pricing page on October 19, 2026. Astro details come from its site, its docs and a hands-on check of Astro 2026.14.0 in October 2026. Sonar data points come from Sonar's own API, queried on the dates given. No affiliate links, no paid placements.

Best Astro Alternatives by Use Case
Closest Mac-native swap, with Apple Ads built in: AppSprint
What it does. AppSprint is a macOS app that combines keyword work with App Store Connect metadata and Apple Ads management. Its MCP server exposes 38 tools — ASO and App Store Connect, analytics reads, and Apple Ads reads, planning and writes — over localhost while the app is open (sources: appsprint.app/mac, appsprint.app/docs/mcp).
Pricing. Pro is $108/year, the same as Astro; it needs macOS 14.6 or later.
Choose it if: you want to stay on a Mac and also run Apple Search Ads campaigns from the same app — or from an agent, since AppSprint's server is the only one we found that can create and edit Apple Ads campaigns.
Skip it if: your reasons for leaving Astro are Google Play, Windows, teammates or a remote agent. AppSprint shares all of those limits.
iOS keyword tracking on any desktop OS: ASO.dev
What it does. ASO.dev tracks App Store keywords with Apple's Search Ads popularity, and also manages App Store Connect and Google Play metadata, releases and reviews. It ships desktop apps for macOS, Windows and Linux plus mobile apps, and deliberately has no web version (sources: aso.dev/download, aso.dev/blog/web).
Pricing. Priced per seat. Keyword tracking starts on Indie at $39/seat/month, or $29 billed annually, with unlimited apps and an unlimited tracking list refreshed every 4 hours; rank history is capped at 30 days on Indie and 60 days on Pro ($89/month). The $19 Console plan covers metadata, releases and reviews, plus a local MCP server ("AI Companion"). An API is in alpha on Pro. There's a 3-day trial and no free plan (source: aso.dev/pricing).
Choose it if: you're iOS-only but work on Windows or Linux, or want keyword tracking that refreshes several times a day.
Skip it if: you need Google Play keyword data — ASO.dev says Google Play ASO analytics aren't available yet — or long rank history on the entry plan.
Both stores, server-side tracking and agent workflows: Sonar
What it does. Sonar (trysonar.app) is a web-based ASO tool for the App Store and Google Play: keyword popularity and difficulty, daily rank tracking on Sonar's servers, competitor keyword gaps and review monitoring. iOS ranks follow Apple's true search order, and iOS popularity is Apple's own number wherever Apple reports one. Every plan includes a REST API (OpenAPI spec), a CLI (@sonarapp/cli) and a hosted MCP server with 63 tools, so an agent in Claude Code, Codex, Cursor or Claude can work with your data whether your laptop is open or not.
Pricing. Indie is $29/month or $290/year for 10 apps and 2,500 keywords; Agency is $149/month or $1,490/year for 50 apps, 10,000 keywords and 5 seats. Both start with a 7-day free trial (card required). For scripts and agents there are API credit packs from $10 with 50 free credits on signup, and the MCP server runs keyless on a small free tier. See Sonar pricing.
A concrete data point. On October 19, 2026, Sonar's API put "budget planner" at iOS difficulty 63 with Apple popularity 51, and Google Play difficulty 63 with an estimated popularity of 42. "Tip calculator" read iOS difficulty 40 (Apple popularity 47) against Google Play difficulty 18 — a keyword that's contested on the App Store and much more open on Google Play (source: Sonar /api/v1/keywords/metrics, US). An iOS-only tool only sees half of that.
Where Sonar falls short against Astro:
- It costs more. $290/year against Astro's $108.
- It isn't unlimited. Indie tracks 10 apps and 2,500 keywords.
- No native Mac app, no local copy of your data. Sonar runs in the browser and through its API, CLI and MCP.
- Popularity below Apple's floor is Sonar's estimate. Apple reports 5 for most long-tail searches; Sonar shows its own calibrated estimate there (and for all of Google Play), labelled as such. Astro shows Apple's figure.
- It's young and founder-led. Keyword history starts when Sonar began tracking a term (2026 at the earliest).
Choose it if: you ship on both stores, want ranks recorded every day without a desktop app running, or want your agent to query keyword data from anywhere.
Analytics plus ASO in one dashboard: Appfigures
What it does. Appfigures combines analytics for your own apps (sales, downloads, revenue, reviews) with ASO tools across the App Store and Google Play. Market-wide download and revenue estimates live in its separate, sales-led Explorer plans (source: appfigures.com/pricing).
Pricing. Keyword tracking starts on Monitor at $44.99/month for 100 keywords; Optimize, the plan built around ASO, is $149.99/month for 500 keywords ($119.99 billed annually). There's a free plan, a trial with no card, and up to 5 users on any plan. Every account gets a hosted MCP server and 1,000 API requests a day; data about other apps costs Public Data credits, priced per data type (source: Appfigures help center).
Choose it if: you want your own sales and downloads next to keyword rankings, so you can see what a metadata change did to installs.
Skip it if: keyword tracking is the main job and budget matters — 500 keywords costs more than Sonar's 2,500 or AppTweak's 500.
Agencies and larger teams: AppTweak
What it does. AppTweak is a full ASO platform with keyword research, competitor intelligence and reporting, plus separately sold products for market intelligence, review management and Apple Ads campaigns, and AI agents for ASO, reviews and reporting (sources: apptweak.com/pricing, AppTweak blog).
Pricing. Essential is $79/month billed annually ($99 month-to-month) for 5 apps, 500 keywords and one seat; Grow and Expand are $299 and $549 a month billed annually. API access, with MCP included, is a separate plan from $166/month billed annually. Every plan has a 7-day trial (billing details required). Our AppTweak alternatives guide breaks down every tier.
Choose it if: you run client work or a larger studio and want deeper data, history and reporting in one platform.
Skip it if: you're a solo iOS developer — it costs several times Astro's yearly price per month.
Choosing the Right Alternative: Decision Framework
If you only ship on iOS and want to stay on a Mac: stay with Astro, or move to AppSprint if you also run Apple Search Ads.
If you're iOS-only but not on a Mac: ASO.dev runs on macOS, Windows and Linux.
If you need both iOS and Google Play: Sonar, Appfigures or AppTweak. Sonar starts at $29/month with API, CLI and MCP included; Appfigures adds analytics for your own apps; AppTweak adds depth, reporting and separately sold market intelligence.
If you want API or agent access that works off your Mac: Sonar (API, CLI and hosted MCP on every plan), Appfigures (hosted MCP and API on every account, with credits for other apps' data) or AppTweak (API and MCP on a separate plan from $166/month billed annually). Astro, AppSprint and ASO.dev's MCP servers all run locally. Our ASO MCP server comparison covers the options in detail.

FAQ
Is Astro ASO available on Windows or Linux?
No. It is a macOS-only application (macOS 14 and up), downloaded from its website (source: tryastro.app). There is no Windows, Linux or web version. ASO.dev runs on Windows and Linux for iOS keyword tracking; Sonar, Appfigures and AppTweak run in the browser.
Does Astro support Google Play keyword research?
No. Astro covers only the Apple App Store. If you publish on both stores, you need a tool that covers Google Play too — Sonar, Appfigures and AppTweak all do. For how iOS and Android ASO differ, see our Android ASO guide.
How accurate is the popularity data compared to Sonar's?
For terms Apple reports, both show Apple's own Search Ads popularity, so they should match. The difference is below Apple's floor: Apple reports a popularity of 5 for most long-tail searches, and Astro shows that 5, while Sonar shows its own calibrated estimate, labelled as an estimate. Sonar also covers Google Play, where all popularity numbers are estimates because Google publishes none. Our Apple Search Popularity guide explains the scale.
Is Astro ASO worth it, and where does its data come from?
For a solo iOS developer on a Mac, usually yes: $108/year buys unlimited keywords, daily rank updates inside the app, and popularity that Astro takes directly from Apple Search Ads, with a 14-day refund window (source: tryastro.app). It stops being worth it once you ship on Google Play, work outside macOS, need unbroken rank history, or need rankings in a script or an agent that doesn't run on that Mac.
How much does Astro ASO cost, and is there a free trial?
$108 a year, shown on the site as $9/month billed annually, for a Single Mac License (source: tryastro.app, checked October 19, 2026). It's the only plan, with unlimited keywords. Before paying you can use the free version, which tracks up to 10 keywords (source: Astro docs); once a subscription activates you have 14 days to request a refund.
Is Astro's unlimited keyword tracking really unlimited?
That's what the pricing page states, with no published cap or overage fee. Any tool that pulls store data has rate limits somewhere, but Astro has no per-keyword metering or tier jump to plan around — the main practical benefit of its model, and a real advantage over Sonar's 2,500-keyword Indie cap.
Can I use Astro with AI agents or MCP?
Yes, locally. Astro ships an official MCP server, in beta, built into the Mac app (source: tryastro.app/docs/mcp). You turn it on in Settings, and it serves 12 tools over HTTP at 127.0.0.1:8089 — list apps, read keywords, rankings and ratings, add apps and keywords, set notes and tags, search the App Store and get keyword suggestions — limited to 60 requests a minute per client. It accepts connections from the same Mac only and runs only while the app is open. Cursor, VS Code, Claude Code and Antigravity connect directly; Claude Desktop needs a Cloudflare quick tunnel. AppSprint and ASO.dev also run local MCP servers; Sonar's and Appfigures' are hosted, and AppTweak's runs on its separate API plan.
Astro or Sonar: which should I pick?
Astro, at $108/year, if you're a solo iOS developer on a Mac who opens the app most days and needs no automation beyond a local MCP server — that's a coherent set of needs and Astro serves it well, with unlimited keywords. Sonar, at $29/month or $290/year, if you ship on Google Play too, work across machines, want ranks recorded every day whether your laptop is open or not, or want an API, CLI or MCP server that works from anywhere. Platform and automation should decide it, not the $182/year price gap.
What are the best Astro ASO alternatives for cross-platform developers?
Three tools cover both stores with server-side daily rank tracking (listed by entry price):
- Sonar (from $29/mo) — App Store and Google Play with API, CLI and hosted MCP included on every plan. Best for agent and script workflows on a small budget.
- Appfigures (from $44.99/mo; $149.99/mo for the 500-keyword ASO plan) — App Store and Google Play plus analytics for your own sales and downloads. Best when you want installs and rankings in one dashboard.
- AppTweak (from $79/mo billed annually) — deeper data, history and reporting, with market intelligence and Apple Ads tools sold separately. Best for agencies and larger teams.
Is Astro cheaper than the subscription alternatives?
Yes. Astro is $108/year, while the subscription tools in the pricing table above start between $15 (Mobile Action Lite, 100 keywords) and $149.99 (Appfigures Optimize) a month. Only AppSprint matches its price. The trade-off is coverage: Astro is iOS-only and Mac-only, with rank history recorded inside a single-license desktop app. For how tool costs compare with hiring help, read our ASO agency vs tool vs DIY breakdown.
Need keyword data for both stores that your agent can reach from anywhere? Start free trial — and if you're iOS-only on one Mac, Astro may be all you need.
