Fledly in one paragraph

Fledly is App Store market intelligence for indie iOS developers. Every day it reads Apple's Top Grossing charts in 23 App Stores, finds the iPhone apps under two years old that already make money, groups them into app ideas and scores each idea on that public evidence. It also tracks your own apps' App Store search ranks, your competitors' listing changes and the keywords worth targeting. It runs in the browser at https://fledly.app/ and inside AI assistants such as ChatGPT and Claude through its MCP server, and it is free to start.

Who it is for

Solo developers and small teams who build iPhone apps and want to pick an idea that people already pay for, then get that app found in App Store search. Typical questions it answers: which young apps are earning right now, which app ideas several different developers have already made work, what those apps charge, and which searches a small app can realistically rank for.

It is not built for analysts who need market-wide download numbers, years of history or Google Play data; see what Fledly is not.

What it does

Data coverage

How the idea score works

Each app idea is a group of young earning apps that do the same job for the same people. Its score has four parts, each 0–100 relative to the strongest idea of the day:

The weighted sum is then adjusted: ideas one developer can't realistically build are marked down, and so are ideas whose revenue looks bought with paid ads (high estimated revenue with very few ratings) or comes from category charts where the revenue mapping is a guess. The verdict is Build at 42 or more when one developer can build it, Consider from 24 to 41, and Pass below that. Every part is shown next to the score, so you can disagree with it.

The weights are rules of thumb, not a calibrated model. The score sorts ideas by public evidence; it does not predict how your app will do.

Revenue numbers are estimates

Fledly does not see any app's sales. Its revenue figures are estimates from Top Grossing chart rank: a published power curve for the US (about $70 million a month for the #1 app, falling with rank), shown as a range from a third to three times the curve's value. Category ranks are converted to overall ranks by comparing apps that appear on both charts the same day; deep in a small category that mapping is a guess, and Fledly marks it. In the other stores the US curve is scaled by each store's rough share of App Store spending, so those figures are rougher still.

Treat them as an order of magnitude: good for sorting and shortlisting, not for valuing a company or planning a budget. The app revenue calculator shows the same curve, and How much do Top Grossing apps make? explains it.

Use Fledly from ChatGPT, Claude and other AI assistants

Fledly has a remote MCP server at https://fledly.app/mcp (streamable HTTP, OAuth sign-in with your Fledly account, no API key). It has 18 tools: young earners, app ideas, Top charts, app lookup, App Store search, keyword suggestions, your tracked apps and keywords, tracking apps, keywords and competitors, competitor reports, saving ideas, metadata checks and keyword fields.

What Fledly is not

Who builds it

Fledly is made and run by Mika Heinonen, an independent iOS developer who ships iPhone apps as a solo developer and built Fledly to answer two questions that kept coming back: which app ideas are already proven by newcomers, and which keywords a small app can win.

Frequently asked questions

Is Fledly free?

Yes, the Free plan costs $0 with no time limit and no card: 1 app, 15 tracked keywords, 3 competitors per app, daily rank checks, the top 3 app ideas and top 3 young apps, MCP access. Pro costs $9 a month or $79 a year and opens every idea, young app and store; Studio costs $24 a month or $199 a year.

Does Fledly support Android or Google Play?

No. Fledly covers the Apple App Store (iPhone and iPad) only.

How accurate are Fledly's revenue estimates?

Rough: an order of magnitude. They come from Top Grossing chart rank with a published curve and are shown as a range from a third to three times the estimate. Fledly sees no real sales data, so use them to compare and shortlist, not to plan with.

How is Fledly different from Sensor Tower, Appfigures or Astro?

Sensor Tower and Appfigures estimate downloads and revenue across the whole market (Appfigures also reports your own app's sales); Astro is a Mac app for keyword tracking. Fledly is a self-serve web tool for indie iOS developers that finds young apps already earning, scores the app ideas behind them and tracks your keyword ranks, from $0. Side by side: Fledly vs Sensor Tower, Fledly vs Appfigures, Fledly vs Astro, Fledly vs Sonar.

Can I use Fledly in ChatGPT or Claude?

Yes. Add the MCP server https://fledly.app/mcp as a custom connector in Claude or a custom MCP server in ChatGPT and sign in with your Fledly account. It works on every plan, including Free. Setup: MCP setup.

Does Fledly have an API?

Not a REST API and no API keys. Programmatic access is the MCP server at https://fledly.app/mcp, which any MCP client can call.
