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. Every price below was re-checked directly on the vendor’s own site on 10 September 2026 — except AppFollow’s tier figures, which are as checked on 6 September 2026 and reconfirmed today (its pricing page is JS-rendered and didn’t fully re-render on a repeat check); where we’d already published a deeper, dated breakdown of a tool, we link to it rather than repeat the full case here.
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 €18/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 rankings and metadata into the same workspace where you research and draft, instead of switching tabs to check what’s actually live
Enterprise tools sometimes leave out items 3 and 6 entirely because their customers have ASO managers who handle drafting and submission elsewhere. For an indie, that is a dealbreaker — and it is the one item where the tools below genuinely differ, not just on price. Most of them stop at a draft you still copy into App Store Connect yourself; Marteso is the exception, with a “Push to ASC” action that submits your approved changes directly.
The six tools, head-to-head
| Tool | Built for | Starting price | Full self-serve plan | Free tier | Metadata drafting | Localization automation | App Store Connect integration |
|---|---|---|---|---|---|---|---|
| Marteso | Indie iOS devs | Free (2 apps, 50 keywords each) | €18/app/month (Pro) | Yes, permanent | AI-assisted, in-app | Yes (auto-translate) | Read + write (“Push to ASC”) |
| Komori | Indie iOS devs | $19.99/month | $19.99/month | 3-day trial, no free tier | No | No | No |
| Appfigures | Mixed | $9.99/month (Connect) | $1,399.99/month (Amplify) | Yes, permanent (Free/Starter — no keyword tracking) | No | No | No |
| AppFollow | Enterprise + agencies | $0 (Free) | $425/month (Team) | Yes, permanent | Partial | Partial | Read only |
| AppTweak | Enterprise | €79/month | €499/month (Grow Plus) | 7-day trial | No | Partial | Read only |
| Sensor Tower | Enterprise | Not published — quote only | Not published — quote only | Trial only | No | No | Read only |
Pricing for Marteso, Appfigures, AppTweak, and Sensor Tower is published on each vendor’s own site and was checked directly there on 10 September 2026; Komori’s figures were checked the same day at komori.tech. AppFollow now publishes real self-serve tiers on its pricing page too — a change from earlier in 2026, when the page routed to a contact form — checked 6 September 2026 and reconfirmed today; see our dedicated AppFollow pricing check for the full picture. Sensor Tower has never published self-serve pricing — see our Sensor Tower breakdown. None of these vendors’ numbers are locked in; verify directly before committing to an annual plan.
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 — 2 apps, 50 tracked keywords per app, daily rank updates, 3 competitors per app, review inbox
- Pro at €18/app/month covers unlimited apps, 500 keywords, AI metadata optimizer, unlimited competitors, weekly email reports
- App Store Connect integration reads live rankings into the workspace, and a “Push to ASC” action submits your approved title, subtitle, keyword field, and description changes directly to App Store Connect — no manual copy-paste, per its own documentation (checked 10 September 2026)
- 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
- AI metadata optimizer drafts title, subtitle, keyword field, and description with character counts and keyword-density checks — you review and approve each field before it ships
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. It runs a free Starter plan plus five paid tiers, checked directly on appfigures.com on 10 September 2026: Starter is $0 with download/revenue analytics but no keyword rank tracking, then Connect at $9.99/month (25 keywords, no daily rank updates) up through Amplify at $1,399.99/month (2,500 keywords, unlimited premium competitors). Daily rank tracking — the point of an ASO tool — only starts at Monitor, $44.99/month. See our full Appfigures pricing breakdown for what each tier unlocks.
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 or Google Play Console submission
- Pricing scales steeply — from $9.99 to $1,399.99/month across five tiers
Who it fits: Teams that primarily want analytics dashboards and treat ASO as a secondary concern. Indies will outgrow the cheap tier quickly (it doesn’t even include daily rank updates) 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. Its pricing page now shows real self-serve tiers directly — a change from earlier in 2026, when the page routed to a contact form — running from a genuine Free plan up through Team at $425/month (billed annually), checked 6 September 2026 and reconfirmed today. See our dedicated AppFollow pricing check for the fuller trail, though note that post predates this change and still describes the contact-form version of the page.
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:
- ASO module is competent but secondary to reviews
- Metadata is read-only, same as every non-Marteso tool here — no push to App Store Connect
- 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 — real self-serve pricing, but enterprise-scoped
AppTweak is one of the most-reviewed ASO platforms on G2 and Capterra, and unlike Sensor Tower it publishes real tiers: Essential at €79/month (500 keywords, 1 seat, 6-month history), Grow at €249/month (1,500 keywords, 12-month history), and Grow Plus at €499/month (3,000 keywords, 24-month history) — all checked directly on apptweak.com on 10 September 2026, unchanged from our last check. Every self-serve tier caps you at a single seat; Enterprise is a custom quote. See our full AppTweak pricing breakdown.
What it does well:
- Deep keyword data and competitive intelligence
- Excellent reporting for stakeholder presentations
- Covers both the App Store and Google Play
- ASO consulting services as an add-on
What it does not do well for indies:
- €79/month entry is the highest of any self-serve tool in this comparison
- No metadata submission — you draft in AppTweak, ship through App Store Connect manually
- No screenshot pipeline
- Single-seat cap on every self-serve tier, even Grow Plus
Who it fits: Teams that want real self-serve pricing but need deeper competitive intelligence than an indie tool provides. Priced above what most solo developers will justify for one or two apps.

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. Its pricing page remains quote-only — checked directly on 10 September 2026, there’s still no self-serve tier or dollar figure published anywhere on the site. See our dedicated Sensor Tower pricing check for what its App Performance Insights module covers and three transparent-pricing alternatives.
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 (€18/app/month) — only platform priced linearly without enterprise minimum
- 10+ apps as a studio or agency: Marteso Pro or AppFollow
2. Do you want AI-drafted metadata and auto-translated localization in the same workspace as your rankings?
- Yes, and you’re fine pushing the final change to App Store Connect from inside the tool: Marteso, via its “Push to ASC” action
- 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.
Other ASO tools worth knowing about
The six above are the ones indie iOS developers ask about most, but they’re not the whole field. We’ve also checked pricing directly, dated, on: AppRadar vs MobileAction, SplitMetrics (which turns out to be three separately-priced products, one of them the former independent AppRadar), data.ai / App Annie (the standalone product no longer exists — Sensor Tower absorbed it), Gummicube (a full-service agency with no pricing page at all, not a self-serve tool), and Asodesk. We’ve also put AppTweak head-to-head with Appfigures if those two are your actual shortlist. If none of the six above quite fit, one of those is worth a look before you book a sales call.
What changed in 2026
A few things worth noting since the last time most “best ASO tools” lists were written:
- 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. Marteso’s drafts can be pushed straight to App Store Connect after approval; everywhere else on this list, submission is still a manual step outside the tool. Komori added AI suggestions in late 2025.
- Pricing in the indie tier compressed. Marteso dropped Pro from €49 to €18/app/month in mid-2026, putting it below Komori for full-platform coverage.
- AppTweak started publishing real self-serve tiers (€79/€249/€499), and AppFollow followed — its pricing page routed to a contact form for most of the year but now shows real tiers directly, as of our 6 September 2026 check. Sensor Tower is the last of the six still quote-only.
