Best ASO Tools for Indie Developers (2026): Prices Compared

Short answer

Choose one ASO tool for the job you can do this month, then read its entry price. ASO tools inform a listing decision. They do not create installs. The copy, the screenshots, and the app's promise still do that work.

We build Mantis and MrGripper. Astro is the ASO tool we use for keyword tracking on those two apps.

The four ASO jobs

Most ASO work falls into four jobs. Match the tool to the job, then check the entry price in the table above.

Tool-by-tool fit

Astro

Astro is a Mac app for App Store keyword tracking. The homepage says it is available for macOS 14 and up. The price block lists one Single Mac License at $9 per month, billed annually at $108, and says prices are in USD and that taxes may apply. The same block, in Astro's words, includes unlimited keywords, popularity and difficulty data, keyword suggestions, charts and rankings, ratings analysis, competitor keyword extraction, keyword translations, and more than 60 countries. Astro's keyword docs say 91 App Store countries are available, and that the free version can track up to 10 keywords. Those country counts are Astro's, and they do not match each other. A paid subscription has 14 days to request a refund by email to hello@tryastro.app, which is Astro's refund policy.

AppTweak

AppTweak is the fit when the next task is keyword research and a listing rewrite across the App Store and Google Play. On Oct 20, 2026 the Essential card for 5 apps printed $79 per month on annual billing ($949 billed annually) and a monthly rate of $99, with 500 keywords, 1 seat, and 6 months of history. The same 5-app selector showed Grow at $299 per month on annual billing ($3,590 billed annually, or $359 monthly) with 1,500 keywords, 1 seat, and 12 months of history, and Expand at $549 per month on annual billing ($6,590 billed annually, or $659 monthly) with 3,000 keywords, 1 seat, and 24 months of history. Enterprise is contact-only. The page changes the currency symbol by location. This check showed a dollar sign, and AppTweak's pricing FAQ says prices are offered in euros, US dollars, pounds sterling, and yen. The plan cards say "Start a 7-day free trial". AppTweak's FAQ says the trial starts after you enter billing information, and the card is charged if you do not cancel before the trial ends. One trial is allowed per product.

Appfigures

Appfigures is the fit when you want reports on apps you connect: downloads, revenue, and reviews, on iOS and Android. Checked Oct 20, 2026 on the Analytics and ASO tab. Starter is the free plan named on the page, and the page does not print a Starter keyword count. Connect is $9.99 per month, or $7.99 per month on the annual display, and that card prints 0 keywords and 0 competitors. Monitor is $44.99 per month ($35.99 on the annual display) for 100 keywords and 0 competitors. Optimize is $149.99 per month ($119.99 on the annual display) for 500 keywords and 0 competitors. The Connected Apps row on the Connect column prints "5, then $1.99 each". A free trial needs no credit card and unlocks Optimize. The pricing FAQ does not say how many days it lasts. When it ends, the account moves to the free plan.

AppFollow

AppFollow is the fit when the daily job is reading and replying to reviews. Checked Oct 20, 2026, the pricing page does not print a dollar amount. It offers a sales conversation, and the page says "Try AppFollow for free" without printing free-tier limits. Confirm the current terms on that page before you budget a reply workflow.

AppScreens

AppScreens makes store screenshots, captions, and localized exports. It does not do keyword research. Checked Oct 20, 2026. Free is $0: 1 saved project, up to 5 screens, essential iOS and Android sizes, and no card. Pro is $8.25 per month billed annually at $99, and the same page lists a monthly Pro price of $25. Scale is $15 per month billed annually at $180, and a monthly Scale price of $50. See the screenshots category for other creative tools.

When you do not need a paid ASO tool yet

If the app has not launched, or the positioning is still moving, a paid ASO subscription is premature. Before paying:

• -Write a specific promise you can turn into keywords.
• -Read competitor titles, subtitles, and top reviews by hand.
• -Draft screenshots that explain the app in the first two frames.
• -Use Astro's free version, Appfigures Starter, the AppScreens free plan, or a trial to check a short keyword list.

Add a paid plan when you have a listing to optimize and a decision the tool will change.

Best for

• -Apps preparing a launch, relaunch, or metadata refresh.
• -Builders who want the entry price and the free tier in one place before they pick a job.
• -Teams choosing one ASO job to improve this month.

Not good for

• -Apps that have not settled the target user or positioning.
• -Teams that expect an ASO subscription to produce installs without better copy and creative.

Internal links

• -Work through the ASO starter checklist first.
• -Compare the two research tools head-to-head in Appfigures vs AppTweak for ASO research.
• -Prepare creative with the screenshots category and AppScreens.
• -Browse the full ASO category.
• -Connect launch timing through the mobile app launch stack checklist.
