The news, explained. Not summarised.

Under every story that matters you get what it actually means, who it hits, and what to watch now. Two paragraphs, no jargon. This is a real example, taken from the app.

Apple’s Tim Cook sees Australia’s social media curbs as ’world-leading’, PM says

What it means

Apple CEO Tim Cook called Australia’s new social‑media rules “world‑leading”. The Australian government has tightened requirements, forcing platforms to take down illegal content within 24 hours.

What follows

The comment may boost Apple’s image as a responsible company, but the stricter rules could raise compliance costs for social‑media firms. Apple’s stock is unlikely to move dramatically, while companies like Meta may feel pressure on margins.

Where the big money goes.

Every quarter the world's 19 largest funds have to tell the SEC what they bought and what they dropped. The radar shows it at a glance: who is moving in, who is moving out, and which stocks a lot of them are moving on at once.

Moves actually filed with the SEC, from the public EDGAR archive, updated Sep 20, 2026. The figure is the value of the position declared in the filing, not the amount traded: a 13F does not contain that. The change is in share count against the previous quarter.
THE NUMBER NO OTHER APP WRITES DOWN

A month and a half goes by between a fund's move and the day you can know about it.

The law gives funds 45 days after the quarter ends to file their 13F. By the time it is public, part of the move has already happened. Nobody says so. We do: for every fund you get how far the stock had already travelled in the meantime — a median across 2,150 real moves.

Which funds actually get it right.

Not an opinion: a measurement of what each fund's typical move returned over the 90 days after filing, across 2,150 moves and real prices. Median, not mean — one stock that exploded should not make a fund look good on a single shot.

Where the data comes from.

The SEC's public archives

Forms 13F and 13D/G, which funds above a certain size are required by law to file. They are public, free and downloadable by anyone on EDGAR. We read them every day.

News from financial publishers

Public feeds from Bloomberg, Reuters, Investing.com and others. The headline and the source stay as published, with a link to the article.

Explanations written by an AI model

They exist to give context to a story or a move. They are not investment advice, and the app says so.

Prices from public market data

Used for the stock chart, the simulated portfolio and to compute the fund ranking.

07

The questions you are asking.

Is it really free? What's the catch?

It is free and there is no catch. We do not sell your data, there are no ads and we do not handle money. The data the app reads is public filings anyone can download: the work we do is reading them every day and telling you what they say.

Do I have to sign up?

No. Open it as a guest and you see everything. An account only matters if you want your simulated portfolio and watchlist on another phone.

Will you tell me what to buy?

No, and that is not a formality. InsiderFlow is an informational and educational tool: it is not a broker, it does not execute orders and it does not move real money. Nothing you read is investment advice or a recommendation to buy or sell.

Can I lose real money in the portfolio?

No. The portfolio starts with ten thousand dollars that do not exist. The prices are real, the money is not: it is there so you can find out whether your ideas hold up before a single real euro is on the line.

Is the data real-time?

The news is, several times a day. Fund filings are not, and that is not on us: the law allows up to 45 days to file them. The app always shows the filing date, and for every fund how far the stock had already moved in the meantime (median: 45 days).

Which phones does it run on?

iPhone, iOS 15 and later. There is no Android version yet.


The filing is public. The work of reading it isn't.

InsiderFlow is free, opens without signing up, and never moves a real euro.
