Tax Days vs. Flamingo
Flamingo and Tax Days overlap on the tax half of the problem and diverge on the other half. Flamingo pairs day counting with visa and residence-permit tracking, which Tax Days does not do at all. Tax Days goes deeper on the tax rules themselves, covers 200+ jurisdictions at a single $29.99/year price, and keeps the record on your iPhone with no account. Here is the head-to-head. (Flamingo's tier prices below are the in-app purchase prices published on its App Store listing as of August 2026; Flamingo does not publish which features sit in which tier, so confirm on flamingo.tax before subscribing.)

Which one is right for you?
Tax Days is best for…
- Anyone who wants one price rather than working out which tier they need.
- People whose problem is tax residency, with immigration status already settled.
- Anyone who wants every jurisdiction included from day one.
- Users who want an audit-ready PDF rather than raw CSV.
Flamingo is best for…
- Anyone tracking visa days and tax days at the same time.
- People who need residence-permit expiry dates watched alongside day counts.
- New York City residents who want city-level tracking inside the tracker.
- Flight and cabin crew, who have a dedicated exemption mode.
Bottom line: If your visa or residence permit is part of the same problem as your day count, Flamingo does something Tax Days does not, and that is a real reason to choose it. If your immigration status is settled and what you need is the tax day count itself, Tax Days covers more jurisdictions at one flat $29.99/year rather than a tier you have to pick correctly, and keeps the record on your own device.
Frequently asked questions
How much does Flamingo cost?
Flamingo's App Store listing publishes three subscription tiers: Settler at $2.99/month or $29.99/year, Resident at $5.99/month or $59.99/year, and Globetrotter at $11.99/month or $119.00/year. Flamingo does not publish a feature-by-tier breakdown, so check flamingo.tax to see which tier includes the trackers you need. Tax Days is a single $29.99/year price with everything included.
Does Tax Days track visas like Flamingo does?
No. Tax Days is a tax residency tracker: it counts days against residency thresholds and does not track visa validity, residence-permit expiry, or entry requirements. Flamingo covers both, including visa requirements from a passport index and document storage. If you need immigration and tax in one app, that is Flamingo's advantage and it is a genuine one.
Which app covers more tax rules?
Tax Days covers 200+ countries plus all 50 US states with their specific statutory tests, the federal Substantial Presence Test, Schengen 90/180, and the UK SRT, all at one price. Flamingo names Schengen, the UK and its constituent nations, France, Switzerland, Cyprus, Malta, US states, NYC, and the presence tests, and lets you build custom trackers beyond that. Flamingo goes deeper on city-level NYC tracking; Tax Days goes broader on countries.
Which one is more private?
Tax Days stores everything on your iPhone with optional iCloud sync through Apple's CloudKit, has no user accounts, and runs no servers of its own. Flamingo also runs on your device and references iCloud sync in its plans. The practical difference to check before choosing is whether any part of the record leaves your Apple account, so read the current privacy policy for whichever you pick.
Is Flamingo available on Android?
Not as of August 2026. Flamingo's own FAQ says an Android version is in active development but not yet available. Tax Days is also iPhone-only, with a Mac build via Catalyst, so neither app helps an Android user today.
Flamingo or Tax Days for a digital nomad?
It depends on which risk is closer. If you are moving between visa regimes and could overstay a permit, Flamingo watching both clocks in one place is worth the tier price. If your visas are straightforward and the exposure is accidentally becoming tax resident somewhere, Tax Days gives you more encoded residency rules for less money, with nothing stored off your phone.
