One developer, a set of tools, and a review date on every page.

What it is

Nomadivu is a set of tools for people who move between countries for months at a time and need to keep several rule systems straight at once: how many Schengen days are left, whether a passport needs a visa for the next stop, where tax residency would start, which eSIM to buy before landing, and which card to spend on. Each of those questions has its own specialist site. This one puts the working parts in one place, with the Schengen 90/180 calculator as the anchor.

It is a tool site, not a travel blog. Where a page carries text, the text exists to explain a number, a rule, or a trade-off that the tool itself cannot show. There are no itineraries, no destination roundups, and no sponsored posts.

Who runs it

Nomadivu is built and run by one person, AFN, a developer who has been writing software since 2009 and running ad-supported websites since 2005, including Toolsvana, a set of browser utilities. There is no team, no agency, and no outside investor. The site opened in April 2026.

That matters for one practical reason: when a page carries a review date and a name, it is the same person every time, and you can reach that person at the contact page. Corrections sent in are checked against the source and, when they hold up, change the page and its review date.

Where the data comes from

The Schengen algorithm follows Article 6 of EU Regulation 2018/1806 and is checked against the European Commission’s own short-stay calculator manual. It runs entirely in your browser; trips are stored on your device and never sent anywhere unless you turn on sync.

Visa rules for 199destinations are resolved from per-nationality visa requirement tables, refreshed on a schedule, with a hand-checked override layer for cases the tables get wrong. Exchange rates come from the European Central Bank reference rates through Frankfurter and update daily. Country metadata, cost-of-living figures and visa policy summaries sync weekly; eSIM plan prices monthly. Tax residency rules for 75 countries are maintained by hand and checked against each country’s tax authority, PwC’s Worldwide Tax Summaries and IRS Publication 901.

Written explanations start as generated drafts and are then read, corrected and dated by a person before they count as reviewed. A reviewed page shows its date and reviewer in the Sources and review panel, and the generation pipeline is not allowed to overwrite it afterwards. As of 2026-08-25, 213 of the site’s 654 pages carry that stamp, and 233country pages link the country’s own tax or immigration authority rather than naming it in passing. Pages without a stamp are still generated copy and should be read as such.

How it earns

Some outbound links are affiliate links. When you open an account or buy a plan through one of them, the partner pays a commission; the price you pay does not change. Every such link passes through a visible redirect on this domain and is marked as sponsored. Partners never see your trips, and the commission does not decide which product a page recommends: the eSIM tables rank by price per gigabyte, and the card comparisons say plainly where each card loses. Display advertising may also appear on some pages. The full list of partners is on the disclosure page.

What it is not

It is not legal, tax or immigration advice, and every page that touches those subjects says so. It is planning information assembled from public sources by one developer. The consequential decisions, a residence permit application, a change of tax residency, a stay that runs close to the 90-day line, belong with a professional who can see your full situation and put their name to the answer.
