If you are an indie iOS developer searching for an ASO tool in 2026, you are walking into a market split into two halves. One half is built and priced for enterprise app marketing teams with dedicated ASO managers. The other half is built for solo developers and small studios who need to do keyword research, ship metadata, and track results without hiring anyone.
This comparison is for the second half. We looked at the six platforms indie iOS developers most commonly evaluate, pulled real pricing, mapped feature coverage, and grouped them by who they actually fit. We work on one of these tools (Marteso), so this is not a neutral review — but the feature table and pricing data are accurate and verifiable on each vendor’s site.
TL;DR — Which tool to pick
- Solo dev, one or two apps, tight budget: Marteso Starter (free) or Komori
- Indie studio, 5–15 apps, needs metadata + screenshot automation: Marteso Pro at €19/app/month
- Agency or B2B studio shipping client apps: Marteso Pro or AppFollow
- Enterprise team with a dedicated ASO manager: AppTweak or Sensor Tower
If you are reading this and unsure which bucket you are in: you are probably an indie. The enterprise buyers do not search for “best ASO tools for indie developers.”
What an indie ASO tool actually needs to do
Before the comparison, here is the workflow the tool needs to fit. If a platform is missing one of these, it is an analytics dashboard, not an ASO tool:
- Keyword research with volume and difficulty — discover terms you can realistically rank for, scored by demand and competition
- Daily rank tracking per country — know where every keyword sits today and how it moved over the last 30/90 days
- Metadata workflow — write, validate, and submit App Store title, subtitle, keyword field, and description without copy-pasting between Google Docs and App Store Connect
- Competitor monitoring — know when a competitor changes metadata, gets featured, or moves up for a keyword you care about
- Review monitoring — see new reviews across storefronts in one place, ideally with sentiment and topic tagging
- Localization — manage metadata across multiple languages without restarting from a blank Google Doc every release
- App Store Connect integration — read live data and submit changes directly, not export-import
Enterprise tools sometimes leave out items 3, 6, and 7 because their customers have ASO managers who handle submission elsewhere. For an indie, that is a dealbreaker.
The six tools, head-to-head
| Tool | Built for | Starting price | Full plan | Free tier | Metadata submission | Localization automation | App Store Connect integration |
|---|---|---|---|---|---|---|---|
| Marteso | Indie iOS devs | Free (1 app, 50 keywords) | €19/app/month | Yes, permanent | Yes | Yes (auto-translate) | Yes (read + write) |
| Komori | Indie iOS devs | $19.99/month | $19.99/month | 3-day trial | No | No | No |
| Appfigures | Mixed | $44.99/month | $149–$299/month | Limited free | No | No | No |
| AppFollow | Enterprise + agencies | ~$139/month | $479+/month | Trial only | Partial | Partial | Yes |
| AppTweak | Enterprise | Custom (~$200+/month) | $1,000+/month | 7-day trial | No | Partial | Read only |
| Sensor Tower | Enterprise | Custom (4-figure) | Custom (5-figure) | Trial only | No | No | Read only |
Pricing for Marteso and Komori is published on their sites. AppFollow, AppTweak, and Sensor Tower do not list full pricing publicly; the figures above are based on reported quotes from indie developers who got demos in 2025–2026. Real quotes vary.
The breakdown
1. Marteso — built specifically for indie iOS developers
Marteso is the tool we make. It exists because every other option on this list either skipped the indie use case or priced it out of reach.
What it does well:
- Free tier is permanent, not a 7-day trial — 1 app, 50 tracked keywords, daily rank updates, 3 competitor apps, review inbox
- Pro at €19/app/month covers unlimited apps, 500 keywords, AI metadata optimizer, unlimited competitors, A/B testing, weekly email reports, Slack notifications
- Direct App Store Connect integration — read live rankings and submit metadata changes without leaving the workspace
- Auto-translate generates a complete localized metadata set the moment you add a language, including title, subtitle, keyword field, and description
- Screenshot pipeline runs XCUITest, device framing, and localization automatically; ships to App Store Connect in one step
- AI metadata optimizer drafts title, subtitle, keyword field, and description with character counts and keyword-density checks
What it does not do:
- No Android coverage — iOS only by design
- No deep enterprise reporting (cohort analysis, multi-org rollups) — those are not indie workflows
Who it fits: Solo developers, indie studios up to 20–30 apps, and B2B mobile agencies shipping client apps.

2. Komori — the closest indie alternative
Komori is a native macOS app focused on keyword tracking for iOS. It is well-built and reasonably priced at $19.99/month for the full feature set.
What it does well:
- Native macOS app, fast and snappy
- 33 storefronts with keyword tracking
- Keyword overlap with competitors
- AI keyword suggestions
What it does not do:
- No metadata editor — you draft elsewhere and copy-paste into App Store Connect
- No App Store Connect integration — read-only via public scraping
- No screenshot pipeline
- No localization automation
- 3-day trial, no free tier
- macOS-only (no web access if you are on Windows or want to check on the go)
Who it fits: Solo developers on macOS who only need keyword tracking and do their metadata work manually. If you need any of the production workflow (metadata, screenshots, localization), Komori is not enough on its own.

3. Appfigures — the long-standing analytics platform
Appfigures has been around since 2010. It started as an analytics dashboard and added ASO features later. The keyword-tracking module starts at $44.99/month and full features run $149–$299/month.
What it does well:
- Long history, stable platform
- Cross-platform (iOS + Android)
- Solid analytics for downloads and revenue
What it does not do:
- No metadata workflow — analytics-only
- No screenshot pipeline
- No localization automation
- No App Store Connect submission
- Pricing scales aggressively past the entry tier
Who it fits: Teams that primarily want analytics dashboards and treat ASO as a secondary concern. Indies will outgrow the cheap tier quickly and find the higher tiers hard to justify.
4. AppFollow — review-management-first, enterprise-priced
AppFollow’s core product is review monitoring, sentiment analysis, and response management. ASO tracking is a bolt-on.
What it does well:
- Best-in-class review inbox if you have a customer-support team
- Cross-platform
- Integrations with Slack, Zendesk, Helpshift
What it does not do well for indies:
- Priced for teams (~$139/month entry, full plans north of $479)
- ASO module is competent but secondary to reviews
- Indies do not typically need enterprise review SLA tooling
Who it fits: Mid-size apps and agencies with active customer support operations. Not indies.

5. AppTweak — the enterprise ASO platform
AppTweak is one of the most-reviewed ASO platforms on G2 and Capterra. It is also one of the most expensive, and explicitly built for in-house ASO managers and consultancies.
What it does well:
- Deep keyword data and competitive intelligence
- Excellent reporting for stakeholder presentations
- ASO consulting services as an add-on
What it does not do well for indies:
- Pricing starts in the low four figures per month for full access
- No metadata submission — you draft in AppTweak, ship through App Store Connect manually
- No screenshot pipeline
- Workflow assumes a dedicated ASO manager exists on your team
Who it fits: Enterprise app marketing teams, ASO consultancies. Not indies.

6. Sensor Tower — mobile intelligence at enterprise scale
Sensor Tower is primarily a market intelligence platform (downloads estimates, revenue estimates, market trends). It has ASO modules but the platform is sold to publishers, investors, and large brands.
What it does well:
- Best-in-class market intelligence (download and revenue estimates across the App Store)
- Trend reports and category analytics
What it does not do well for indies:
- Pricing is custom, typically four-figures-per-month and up; many seats and a heavy onboarding
- ASO features are secondary to market intelligence
- Not designed for the indie workflow at all
Who it fits: Public-company app publishers, investment analysts, ad networks. Not indies.
How to decide in 60 seconds
Answer two questions:
1. How many apps are you running?
- One app: Marteso Starter (free) or Komori ($19.99/mo) both work. Marteso adds metadata workflow on top.
- 2–10 apps: Marteso Pro (€19/app/month) — only platform priced linearly without enterprise minimum
- 10+ apps as a studio or agency: Marteso Pro or AppFollow
2. Do you need to ship metadata changes through the tool?
- Yes (you want one workflow from research to submission): Marteso
- No (you are happy drafting in Google Docs and pasting into App Store Connect): Komori covers tracking, Appfigures covers analytics
If you find yourself in the “I need the enterprise data” category but the pricing is out of reach, the honest answer is: do less. The indie-priced tools cover 80% of what the enterprise tools cover, and the missing 20% is mostly reporting volume that an indie team would not have time to act on anyway.
What changed in 2026
A few things worth noting since the last time most “best ASO tools” lists were written:
- App Store Connect API surface widened in early 2026, making it easier for tools like Marteso to integrate writeable metadata workflows. The enterprise tools have not caught up; they are still read-mostly.
- Apple Search Ads popularity data became more reliable, narrowing the data quality gap between enterprise and indie tools.
- AI metadata generation moved from gimmick to default. Marteso and a few others now treat AI drafts as a baseline; manual editing happens on top. Komori added AI suggestions in late 2025.
- Pricing in the indie tier compressed. Marteso dropped Pro from €49 to €19/app/month in mid-2026, putting it below Komori for full-platform coverage.
