How it works

How Daysafe counts your days — in detail.

Where each day comes from, what counts as a day, how every rule is calculated, and what happens when data is missing. Nothing here is hidden in the app either: every day and every number can be opened and explained.

01

Where your days come from

Three sources fill your calendar, and Daysafe fills in the obvious days between them. Your own edit always wins.

Added by you1st

Anything you enter or correct. It always wins for that day. Remove your edit and the automatic record comes back.

Locationauto

Allow “Always” and Daysafe notes the country — and the U.S. state — as you move. The coordinates are turned into a place on your iPhone and deleted right after.

Photospast

For trips before you installed the app: the place and date of photos on this phone. You review the trips found before anything is added. Nothing is uploaded.

Filled inlast

A day between two known days in the same place. Marked as filled, so you always see it wasn’t recorded directly.

02

What counts as a day

A day counts for every place you were in during any part of it. That is how the Schengen rule and most U.S. states count, and it’s the cautious choice.

Any part of a dayBeing in a place at any time between 00:00 and 23:59 local time counts the whole day for it.
Border daysCrossing from Portugal to Spain counts the day for both. The report lists both places.
FlightsDeparture and arrival days count for the places you were in. A day spent entirely in the air can be marked ✈️ and counts toward nothing.
Days at seaA day entirely at sea can be marked 🌊 and counts toward nothing.
Time zonesThe date is the local date where you were, not your home time zone.
03

When a day is missing

Phones run out of battery and location gets switched off. Daysafe never guesses a day into a rule.

Same place on both sides — Florida on Aug 5 and Florida on Sep 9 — the days between are filled in and marked that way (up to 60 days; 7 if one side comes only from photos).
Different places — Florida on Jul 16, New York on Jul 20 — the days between become a gap. You answer with one tap; until then those days count toward nothing.
Gaps are outlined, never red, and the report says how many unknown days there are.

Each rule, and how it’s counted

Every rule card shows the same three things: the number, the date to act on, and the method in small print. The rule screen links to the official source and, where we have verified it, the date we checked.

🇪🇺Schengen 90/180
EU Regulation 2016/399, Art. 6
How it’s countedAny 180 days ending on the date you check; at most 90 of them inside the Schengen Area. Entry and exit days count. Days drop out of the window one by one.
What you seeDays left today, “leave by” if you stay without a break, and when the first days free up.
🇺🇸183 days in a U.S. state
The state’s tax residency day count
How it’s countedDays in the state per calendar year (Jan 1 – Dec 31), any part of a day counts.
What you seeDays so far, days left before the line, and the date the counter resets.
🌐183 days in a country
The country’s tax year
How it’s countedDays per tax year in one country. The tax year starts Jan 1, Apr 6 (UK) or Jul 1 (Australia) — you choose when adding the rule.
What you seeDays used of 183 in the current tax year.
⚖️U.S. Substantial Presence Test
IRS · Substantial Presence Test
How it’s countedAt least 31 days this year, and this year + ⅓ of last year + ⅙ of the year before ≥ 183. Some days don’t count under the law (certain visas, commuters) — the rule screen says so; check them with your tax professional.
What you seeThe weighted total with the full table, and how many more days would meet the count. No residency verdict.
🇺🇸ESTA · 90 days
U.S. Visa Waiver Program
How it’s countedUp to 90 days per visit to the U.S. Short trips to Canada, Mexico or the Caribbean during a stay don’t reset the count.
What you seeDays used on this visit and the last day of the allowed stay.
🇺🇸B-2 · 6 months
U.S. visitor visa
How it’s countedCounted from the first day of your continuous stay in the U.S., as recorded in Daysafe. Your I-94 record is what officially applies.
What you seeDays used and days left on this stay.
＋Your own counter
You set it
How it’s countedAny places, a rolling window of N days or a calendar year, “at most” or “at least” a number of days.
What you seeA preview of the number as you build it.

Status colours: green — more than 14 days and more than 15 % left; orange — 14 days or 15 % or less; red — over. Each status also has a word, so colour is never the only signal.

Planning a trip

For Schengen, two questions on one screen.

Can I go? Enter the dates. You see the peak count during the trip and, if it goes over, the day it breaks and the longest stay that fits. How long can I stay? Enter only the arrival date. You get the number of days and the latest day to leave, counting the days that free up as old trips drop out of the window. Date of control. Pick any date to see what a border officer would count then, and which trips fall in that window. Plans are saved separately from real days and never mix into your report.

Show it at the border

One tap opens a large, high-contrast Schengen screen: days used, days left, and your trips in the current window with dates. Works without internet.

It’s your own record, not an official document — the officer’s count is what applies.

Reminders and widgets

Each reminder has a date and an action. They’re local notifications from your iPhone, and one switch in Settings turns them off.

Schengen: leave within 14 daysNov 3

To stay within 90/180, leave the Schengen Area by Tue, Nov 17.

14, 7 and 1 day before the date to leave.

183 days · NY: 30 days to the limitNov 2

If you stay, you reach the limit on Wed, Dec 2.

30, 14 and 7 days before a day-count limit.

Weekly checkSun

3 days need a quick check. It takes a few seconds.

Sundays, only if some days are unknown.

Widgets: small (one rule), medium (two rules) and a lock-screen widget — the number plus the date to act on.

What we store, and where

WhereOn your iPhone and in your own iCloud backup. We have no servers holding your days.
AccountNone. No sign-up, no email.
PhotosRead on the phone for place and date only. Not uploaded, not analysed for content.
TrackingNo ads, no analytics SDKs, nothing sent automatically. Diagnostics leave the phone only if you choose to share them.
