Day31 vs Flamingo
The closest match-up in the category: two iPhone apps that auto-record your border crossings and keep the record on your device.
The short version
Flamingo (now branding as Flamingo Compliance) is the app most similar to Day31: automatic trip recording across countries, US states, and New York City, a Schengen 90/180 calculator, and a stated on-device storage model. It goes wider on travel planning — an IATA-synced passport index and document storage — while Day31 goes deeper on the record itself: years of past travel rebuilt from photo metadata, Canadian provinces, Yonkers, 33 languages, and a fully offline, account-free architecture. If you want a travel planner with compliance features, look at Flamingo; if you want the most complete and private day-count record, that's Day31.

Where Flamingo is stronger
- Passport index. Visa requirements for any destination by citizenship, synced to the IATA database — genuinely useful for planning, and something Day31 doesn't try to replicate in-app.
- Document storage. Attach boarding passes, leases, and supporting documents to trips, so proof of travel lives with the day counts.
- Advisor-oriented exports. Customizable CSV reports developed, per its site, in consultation with lawyers and tax advisors.
- Visa and permit tracking. Long-term visa and residence-permit day rules (presence and absence caps) are built in.
Where Day31 is different
- The past, recovered. Day31 rebuilds years of travel from your photo library's metadata in seconds — the single biggest difference in practice, because residency questions are usually about years already gone.
- Nothing leaves the phone. No account at all, no analytics on your movements, full functionality in airplane mode; backup, if you enable it, is your own iCloud.
- Deeper jurisdictions. Canadian provinces and Yonkers alongside countries, US states, NYC, and Schengen.
- 33 languages and an iOS-native interface — built to disappear into the iPhone rather than feel like a ported tool.
Frequently asked questions
Is Flamingo as private as Day31?
Closer than most. Flamingo states on its website that travel data is stored locally on your device, with iCloud sync as a paid option — a genuinely similar architecture to Day31's. Both apps keep the record on the phone. The practical differences are elsewhere: history rebuild, jurisdiction depth, and breadth of polish.
Which app covers more jurisdictions?
Both track countries and US states, and both handle New York City. Day31 adds Canadian provinces and Yonkers at the city level. Flamingo counters with a passport index synced to the IATA database and visa-requirement lookups — coverage of a different kind, aimed at trip planning rather than day counting.
Can either app recover travel history from before I installed it?
Day31 can — its photo-metadata rebuild reconstructs years of past travel from your photo library in seconds. Flamingo does not advertise a photo-based rebuild; like most trackers, its record starts when the app starts.
Is Flamingo finished?
Some headline features on its site — automatic tax-residency assessment and short-term visa tracking — were marked "coming soon" when we checked in August 2026. Day31's core toolkit (automatic counting, visa limits, residency thresholds, alerts) is shipping today.
