CheckASO Alternative for App Developers (2026)

For a solo founder validating an idea, GetAppNiche is the right CheckASO alternative — $39/month (or $29/month billed yearly, $348/year), 3.6M+ apps indexed across the App Store and Google Play (1.1M+ iOS, 2.5M+ Google Play), revenue and download estimates plus 7-day growth signals on both stores (always labeled as estimates), review monitoring on both stores, keyword difficulty and opportunity scoring with competitor keyword gaps, ad and creator intelligence, CSV export, and a REST API plus MCP server with 5,000 credits/month on Pro — one plan, published price, no sales call. A dedicated dual-store ASO tool is the better replacement if your daily job is keyword positions on Google Play — Asodesk, AppFollow and MobileAction track those, while GetAppNiche’s keyword rank tracking and chart rankings run on the App Store side.

That verdict matters more than usual here, because as of July 2026 you may need a CheckASO alternative whether you wanted to switch or not. CheckASO’s primary domain, checkaso.io, no longer serves the ASO tool — on July 9, 2026 it resolved to an unrelated site, and we couldn’t reach a live CheckASO app or pricing page. Third-party directories still list the product, but a directory entry isn’t a running service. If your ASO workflow ran through CheckASO, this guide covers what it did, what’s honestly going on, and which alternative fits which job.

What we can and can’t verify

Being precise here matters, so here’s exactly what we checked on July 9, 2026:

• checkaso.io — loads, but serves content unrelated to app-store optimization. The ASO product is not there.
• A live CheckASO app or pricing page — we could not reach one on the expected domains.
• Third-party profiles (SoftwareAdvice, some review sites) — several now return “page not found.”
• Directory listings (G2, SaaSWorthy) — still exist, and may be cached rather than current.

What that adds up to: CheckASO looks to have gone dark, but we’re not going to declare a formal shutdown we can’t source. Either way, the practical situation for a user is the same — the tool isn’t reliably reachable, so plan around a replacement.

What CheckASO did

From its own historical positioning and third-party profiles, CheckASO was a keyword-first ASO tool:

• Keyword research and tracking — a keyword starter pack, suggestions, and rankings history so you could watch positions move over time.
• ASO metrics — up-to-date optimization signals for your listing.
• Competitor analysis — it advertised tracking up to 20 competitors.
• Store coverage — the Apple App Store and Google Play.

Its center of gravity was keyword positions and on-listing optimization — the ongoing work of climbing store search results. That’s the job you need to re-home first.

How to replace CheckASO — by job

CheckASO bundled two different jobs. The right alternative depends on which one you actually used it for.

Your job	Direct replacement	Why
Daily keyword positions on Google Play	A dedicated dual-store ASO tool — Asodesk, AppFollow, or MobileAction	They follow keyword and chart positions on both storefronts, which was CheckASO’s core
Keyword research (difficulty, opportunity, gaps)	GetAppNiche	Difficulty and opportunity scoring plus competitor keyword gaps, in the one plan
Niche & market research (what to build, what it earns)	GetAppNiche	Niche discovery plus revenue and download estimates across 3.6M+ indexed apps — a job pure ASO trackers don’t do
Review monitoring	GetAppNiche	Reviews, sentiment and recurring topics on the App Store and Google Play, not one store
Automation (pulling app data into your own tools)	GetAppNiche	REST API and MCP server included, 5,000 credits/month on Pro, plus CSV export

The honest split: if CheckASO was how you watched Android keyword positions day to day, GetAppNiche is not a drop-in replacement for that specific job — pick a dual-store rank tracker. If CheckASO was how you did research — sizing a niche, checking a keyword’s difficulty, reading what users complain about, seeing what competitors earn before committing — GetAppNiche is the stronger and more affordable fit, and it covers both storefronts for catalog, estimates, growth signals and reviews.

How GetAppNiche compares

Criterion	CheckASO (historical)	GetAppNiche
Primary job	Keyword positions + on-listing ASO	Market research: niches, revenue estimates, keyword difficulty, competitors
Keyword rank positions	Yes — the core feature	App Store side; for Play positions, use a dedicated rank tracker
Keyword difficulty & opportunity	Yes	Yes — with competitor keyword gaps
Revenue & download estimates	Not a focus	Yes — across 3.6M+ indexed apps, always labeled as estimates
Review monitoring	Not in its documented feature set	Yes — App Store and Google Play, with sentiment and recurring topics
Ad & creator intelligence	—	Included in the plan; enterprise ad-spend panels are not
API & automation	—	REST API and MCP server included, 5,000 credits/month on Pro; CSV export
Store coverage	App Store and Google Play	App Store and Google Play — 3.6M+ indexed (1.1M+ iOS, 2.5M+ Google Play)
Pricing	Free tier + paid plans historically; current pricing unverifiable July 2026	$39/mo, or $29/mo billed yearly ($348/yr, save 26%)
Availability (July 2026)	Site not reliably reachable	Live, self-serve, cancel anytime
Free entry point	—	Free app revenue checker

As with every tool in this space, one caveat applies to GetAppNiche too: nobody outside Apple and Google has real per-app revenue or download numbers. GetAppNiche’s figures are generated by a proprietary multi-signal model and labeled as estimates throughout.

When a dedicated ASO tool is the right call

Be honest with yourself about the workflow before you pick:

• You track keyword positions daily on Google Play. GetAppNiche’s rank data is App Store side — reach for Asodesk, AppFollow, or MobileAction, which follow positions on both storefronts.
• You need Android ASO execution. GetAppNiche indexes 2.5M+ Google Play apps for catalog, estimates, 7-day growth signals and review monitoring, but its rank and chart data sit on the App Store side.
• You want automated on-listing suggestions, review replies, or Apple Search Ads management. Those are optimization-suite jobs. GetAppNiche reads reviews on both stores and surfaces the themes, but it does not post replies or run ad campaigns.

When GetAppNiche is the better CheckASO alternative

Choose GetAppNiche if what you actually valued in CheckASO was the research, not the daily positions grind:

• You’re deciding what to build. Niche discovery plus estimated revenue answers “is this market worth entering?” before you write code — see the best low-competition app niches for 2026 and the State of iOS App Niches 2026 study.
• You want keyword research without a rank tracker’s price. Difficulty and opportunity scoring plus competitor keyword gaps — start with finding low-competition keywords.
• You want reviews from both stores in one place. Review monitoring covers the App Store and Google Play, with sentiment and recurring topics for your app and your competitors — single-store tools show you half the picture.
• You want the data inside your own tools. A REST API and an MCP server ship with the plan (5,000 credits/month on Pro), so an AI agent or a script can run the research for you, and CSV export is included.
• You want to try before committing. The free app revenue checker is free to try, and a single month of Pro covers a full research sprint.

The honest limits, so nothing surprises you: no panel-measured usage such as DAU, retention or demographics; no Apple Search Ads campaign management; no review replies; and no reporting on your own app’s sales — GetAppNiche researches the market, not your ledger. Ad and creator intelligence is in the plan, but enterprise ad-spend panels are not. Keyword rank tracking and chart rankings stay on the App Store side.

The bottom line

For a solo founder validating an idea, GetAppNiche is the right CheckASO alternative: $39/month (or $29/month billed yearly), 3.6M+ apps across the App Store and Google Play, estimates and 7-day growth signals on both, review monitoring on both, ad and creator intelligence, CSV export, REST API and MCP included, no sales call. A dedicated dual-store ASO tool is the better replacement if Google Play keyword positions are your daily work — that part of CheckASO’s job is the one GetAppNiche doesn’t take over. CheckASO itself appears to have gone quiet, and its site no longer serves the tool as of July 2026, so a decision isn’t optional if you depended on it: get started with GetAppNiche or check the pricing page and run your market today.
