Show HN: Nomad Tracker, a local-first iOS app to track visas and tax residency

Hi HN, I’m full stack developer (formerly iOS) and I just launched Nomad Tracker, a native iOS app to help digital nomads track physical presence across countries for visa limits and tax residency.

Key idea: everything runs on-device. No accounts, no cloud sync, no analytics.

Features:

- Calendar-based day tracking per country. - Schengen 90/180 and other visa “runways”. - Fiscal residency day counts and alerts. - Optional background location logging (battery-efficient, never overwrites manual data). - Photo import using metadata only (no image access). - On-device “Fiscal Oracle” using Apple’s Foundational Models to ask questions about your own data. Also you can choose AI models for this, but not local.

I created this because other apps felt limiting and didn’t do what I needed. This app is visual, user-focused, and designed to make tracking easy and clear.

Happy to answer questions or discuss the technical tradeoffs.

Nice execution. The local-first approach is a smart call for this kind of data — most people won't trust a cloud service with their exact location history across countries.

One nuance I've run into working in this space: the 183-day rule gets treated as universal, but the reality is messier. Some countries count partial days, others don't. Some have "center of vital interests" tie-breakers that override day counts entirely. And for US citizens, the day count is almost irrelevant — worldwide taxation applies regardless of where you sleep.

The Schengen rolling window is genuinely confusing for people and a strong feature to nail. Curious how you handle the edge cases where someone holds a residence permit in one Schengen country but travels freely across others — the 90/180 rule doesn't apply the same way in that scenario.

Congrats on the launch.

Thank you for the feedback and your time. Absolutely, the days count is kind of controversial. It is more a bunch of criteria you have to fulfill.

I didn't know that about US citizens . I received some feedback to include US states, and maybe I might add it, but I don't know if the effort makes sense.

About Schengen; wow, this is a really good question. I didn't know about this edge case, I'm going to prepare it for the next release.

If you have more feedback please send an email to hello@thenomadtracker.com, I'm very open to hearing this kind of feedback or ideas!

Hello! Gotzon here. I would love to have some feedback, specially if you are a digital nomad!

I'm open to hear about your pain points and try to solve them.
