Most indie developers publish an app, then realize no one can find it. Without keyword data, you are left guessing about which terms to target, which competitors to watch, and whether your metadata changes moved the needle. That leaves you making app store optimization (ASO) decisions without much visibility. The right ASO tool usually comes down to:
- Price
- Platform coverage
- Data reliability
Free alternatives cover the basics for most builders. A keyword data shift in late 2025 changed what paying subscribers actually get. The stores still offer a large audience. Search is a discovery path for finding apps. The Apple App Store now serves 850 million weekly users. The Google Play Apps Home redesign drove 25% more monthly visitors year over year.
For most indie builders, the right ASO tool usually costs between $0 and $10 per month. Anything above $40 needs a clear return. The core claim is simple: most indie builders should start with free platform tools, then add one low-cost ASO subscription only when keyword data or competitor tracking justifies it.
The free baseline you already have
Native platform tools usually cover your own app performance well enough that many indie builders can delay paying for a third-party ASO tool. Use these tools first to understand your funnel before you buy outside data.
Before you spend anything, use these native tools to:
- measure traffic
- test listings
- spot conversion problems inside your own funnel
That gives you a baseline for your own app before you pay for outside-in keyword data.
App Store Connect (included with $99/year Apple Developer Program)
Apple provides impressions, conversion rates, and download counts. You can filter by acquisition source to see how much traffic comes from search. Apple's Product Page Optimization gives you free A/B testing for icons, screenshots, and preview videos, with built-in confidence levels.
What you will not get:
- Keyword volume scores
- Keyword difficulty data
- Competitor keyword rankings
- Historical rank tracking
Your data is limited to your own apps.
Google Play Console (one-time $25 fee)
Google offers Store Listing Experiments through the Play Console for free A/B testing of graphics and localized text. You also get acquisition source tracking and market insights. App store metadata fields can vary by platform. You weave keywords naturally into your title and descriptions instead.
Both platforms are the starting point. They tell you what is happening with your own app. They do not tell you what your competitors are doing or which keywords are worth targeting.
Why keyword data reliability changed in late 2025
Late-2025 changes made App Store keyword difficulty less reliable. If you pay for keyword scores, treat those scores more cautiously than before.
In June and August 2025, Apple made notable changes to App Store search and ASO behavior. Many keywords began returning a minimum score of 5, with no official announcement. One paying user of multiple ASO tools wrote that all tools were affected. The tools appeared to respond differently:
- Appfigures said it found an alternative data source
- Astro stopped updating keyword popularity data and restored a backup from early October, so users may see historical popularity values rather than current ones
- AppTweak and MobileAction provide estimated ASO metrics, though their methods for handling missing App Store keyword difficulty values are not documented in the available sources
- APPlyzer was described as less affected because it uses its own independent model
The practical takeaway is simple: cross-reference difficulty scores before making metadata decisions.
With that caveat in mind, 2 tools at the $9 to $10 price point still stand out for most indie builders.
The $9 to $10 per month tier: best value for most indie builders
Most indie builders do not need an enterprise ASO suite. At this price point, the decision usually comes down to 2 options: a focused iOS keyword tool or a broader cross-platform tool.
Lower-cost tools add the missing layer that native platform tools do not give you. They give you outside-in keyword tracking and competitor visibility. That fits small teams and solo builders.
Astro: $9 per month (Mac only, iOS only)
Astro is a Mac desktop app priced at $9 per month billed annually. You get unlimited keyword tracking with popularity and difficulty data across many countries. The tool also generates keyword suggestions and extracts competitor keywords.
That feature set matters most if you build only for iOS and want a narrower workflow focused on search terms and competitor metadata.
The constraints are real. Astro is Mac only and iOS only. Following the Apple algorithm change, keyword data is frozen from before October 2025. Verify current data quality before committing.
Appfigures: $9.99 per month (cross-platform, web-based)
Appfigures Connect covers apps and keywords on a low-cost paid plan. It also includes review replies, keyword tracking, and category rank updates. It works on both App Store and Google Play through a web interface.
That makes it the more practical option if you ship on both platforms or want analytics and basic ASO in one place.
A free tier exists for exploring the interface. The $9.99 Connect plan is a strong paid entry point for builders who need both analytics and basic ASO in one place.
If you build only for iOS and own a Mac, Astro is the more focused keyword tool. If you ship on both platforms or need analytics alongside ASO, Appfigures is the more practical choice.
The $29 to $59 per month tier: when upgrading makes sense
Paying more only makes sense when better data or workflow savings can realistically cover the subscription. If your app is early, this tier is often too expensive for the value you get.
The upgrade decision should follow revenue, not curiosity. One indie developer described the subscription as a large revenue share while using only 5% of the features. That tradeoff will not make sense for most small apps.
AppFollow: free or $39 per month
AppFollow free tier is one of the more capable options in this price range. You get apps, category rankings, and Slack integration, with keyword tracking available on the free plan. The ASO plan includes additional features beyond the base offering.
That mix is useful if you want review management and lightweight competitor tracking before committing to a paid subscription.
AppFollow offers a 10-day free trial.
AppVector: free or $29 per month
AppVector's pricing page explicitly labels its free tier "For Indie Developers & New App Launches." The paid plans scale from there.
It is worth evaluating if AppFollow free tier feels too limited and you want another low-cost step up.
ASODesk: free or $59 per month
ASODesk free tier includes keyword, competitor, and review coverage through the free offering. Review management on the free tier is useful if you want feedback workflows without paying for a separate support tool.
Its paid plans add more tracking capacity.
A practical upgrade trigger is simple: move up when better keyword data is likely to pay back the subscription cost.
Builder-built alternatives worth watching
Newer ASO tools built by indie developers may fit small budgets better than established platforms. Pricing pressure is one of the clearest pain points in this category, which is why these tools are worth watching.
These tools have shorter track records, so it makes sense to watch them rather than treat them as automatic replacements.
Altis is available as software for Mac. Its creator built it because existing tools were too expensive for indies and stored all niche discoveries on their servers. GrowASO's documented plans are priced at various tiers. RespectASO is free, open-source, and self-hosted.
A top market gap in one community analysis is affordable ASO tooling. These builder-built alternatives are trying to fill it.
Whether you choose an established tool or a builder-built alternative, 4 features matter more than the rest.
Which features actually move the needle for solo developers
Solo developers do not need every feature an enterprise ASO suite can sell. They need a short list of capabilities that help them make better ASO decisions without paying for excess tooling.
In practice, 4 capabilities tend to matter most.
Keyword research comes first
One indie developer describes validating keyword demand before writing any code as a repeatable workflow. Some builder accounts emphasize researching keywords early when evaluating app ideas, and external keyword research guides cover specifics like difficulty filtering and long-tail terms.
You need:
- Keyword difficulty scores
- Daily rank tracking
- Keyword suggestions
Those features help you choose targets and measure whether metadata changes are helping.
Competitor tracking stays narrow
Track a small set of direct competitors. Monitor their keyword rankings weekly. Watch for metadata changes around seasonal moments. Free tiers on AppFollow and ASODesk cover this for most builders.
A narrow watchlist keeps the work manageable and gives you clearer comparisons.
Localization is the overlooked hack
You can use the Mexico locale keyword field in Spanish (Mexico) to capture additional English search terms in the US market without translating your app. Populate other locale keyword fields with English keywords to expand your keyword surface area at zero cost.
Using extra locale keyword fields can increase search coverage without adding paid tooling.
A/B testing starts free
Both Apple and Google offer free built-in testing. Use native store tools until your app has consistent organic traffic and a specific hypothesis that native tools cannot test.
That keeps costs down while you are still learning what converts.
Building your ASO stack under $20 per month
Most indie builders can cover the basics with free platform tools plus one paid subscription. This approach keeps costs low while still giving you keyword research, competitor tracking, and review management.
Sequence the build so you exhaust free tools before paying for anything.
- Start with App Store Connect and Google Play Console for baseline analytics and free A/B testing
- Add AppFollow free tier for review management and competitor tracking across apps
- Use AI assistants (ChatGPT, Claude, Gemini) for metadata copywriting and keyword brainstorming. A community workflow documents feeding competitor app descriptions alongside target keywords to generate metadata variations
- When you need keyword difficulty data, add Appfigures Connect at $9.99 per month or Astro at $9 per month
This stack gives you the core workflow without pushing you into enterprise pricing too early.
Skip anything above $40 per month until your app revenue clearly justifies it. Cross-reference keyword scores across 2 tools before acting on them. Apple now uses LLM-generated app tags from your metadata, which means clear, human-readable descriptions may outperform dense keyword strings.
Your first paying users will tell you more about which keywords matter than any tool. Pick one from this list, run it for a trial period, and let the ranking data guide your next metadata update.
Final thoughts
Most indie builders do not need to spend much on ASO tooling at the start. Free platform analytics plus one low-cost paid tool will usually cover the highest-value work.
If you are choosing today, start with the native dashboards, add one paid layer only when you need outside keyword data, and treat late-2025 keyword scores with caution. That is the simplest way to keep costs low without flying blind.
If this approach fits your app, start small and track what changes rankings over the next month. Then decide whether the subscription earned its place in your stack.
