Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 18 of the 42 other app store optimization tools we grade
AppSigma tracks App Store keyword positions every day, compares an app with the apps ranking beside it, and labels reviews with AI by sentiment and topic. The same data is offered as a REST API and as an MCP server, so assistants such as Claude, ChatGPT or Cursor can read rankings and add keywords. Paid plans share every feature and differ by apps and team size.
To get you started, here are 9 things to know about AppSigma, taken from its own pages and our grades.
You add apps, keywords and markets in a web dashboard, or connect the MCP server to your assistant, before it tells you much.

The report card
Best for App Store keyword tracking over MCP
AppSigma tracks App Store keyword positions daily, finds keyword gaps against the apps ranking beside yours and labels reviews by topic with AI, and its MCP server lets Claude, ChatGPT or Cursor read the data. Starter is $19.99 a month for 10 apps. It covers Apple's App Store only, though, there's no annual discount, and the free plan stops at 5 keywords.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Starter is $19.99 a month for 10 apps and 3 team members, about this category's $19 middle, and only monthly prices are listed. Pro is $49.99 for unlimited apps and 10 people. |
| Free plan and trial | C | A free plan with no card: 1 app and 5 keywords in one market with daily positions, the newest 500 reviews analyzed and 1,000 API credits. Five keywords is a cap you'll hit straight away. |
| Features | C | Daily ranks with popularity and difficulty, competitor keyword gaps, visibility scores, AI review labels, 180 days of chart history and alerts. The gap is in its own listing: App Store only, with Google Play not mentioned. |
| Ease of use | C | No rating on record. You add apps, keywords and markets in a web dashboard, or connect the MCP server to your assistant, before it tells you much. |
| Platforms and integrations | B | Web only, with no desktop or phone app. A REST API and an MCP server on every plan reach Claude, ChatGPT and Cursor, and it links to App Store Connect and Figma. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who AppSigma is for
- Fits if you work in Claude, ChatGPT or Cursor and want App Store ranks inside it
- Works for small teams tracking up to 10 iOS apps on one $19.99 plan
Who it is not for
- Skip it if you have an Android app, as Google Play isn't covered
- Tight if you're staying free, since the free plan tracks 1 app and 5 keywords in one market
- Watch out: paid plans list unlimited keywords, but daily positions are described as covering up to 500 per app
- Watch out: only monthly prices are shown, with no discount for paying yearly
- Pricey if more than 3 people need access, since 10 team members means Pro at $49.99 a month
Good to know
Good for
- Indie iOS developers who want daily keyword ranks at a low monthly price
- Developers who work with an AI coding assistant and want ASO data in it
- Small teams tracking several apps on one plan

- It covers Apple's App Store only; the site says its data comes from the public iTunes Search API, and Google Play is not mentioned.
- The free plan tracks just 1 app and 5 keywords in one market.
- Only monthly prices are shown; no annual discount is listed.
- Paid plans list unlimited tracked keywords, but daily positions are described as covering up to 500 keywords per app.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace AppSigma you would be making keyword rankings and popularity scores from both app stores, gathered every day. That is not a weekend's work, with an AI app builder or without one.
It costs $239.88 a year.
What you could not
- Keyword rankings and popularity scores from both app stores, gathered every day.
- Search volumes for millions of keywords, gathered and kept up to date.
- Daily checks of where your pages rank in search results.
- It plugs into other products, Claude, ChatGPT and Cursor among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. AppSigma’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
