One83

One83 counts the days you are physically present in Puerto Rico, the number your bona fide residency rests on. EVERY DAY COUNTS ONCE Other trackers credit a travel day to two places at once, so their yearly totals add up to more than the year itself. One83 keeps one record per calendar day. If any part of that day was spent in Puerto Rico, the whole day counts as a Puerto Rico day, which is the rule that actually applies. The day you fly out and the day you fly home both count, and no day is ever counted twice. YOUR DAYS, FOUND FOR YOU Connect Google Calendar or the calendar already on your phone and One83 reads the flight events sitting in it, turning arrivals and departures into presence days without any typing. Turn on location and it records island crossings on its own, even when a flight never made it into a calendar. Any day can be corrected with a tap, and your correction always wins over anything the app worked out for itself. ALL FOUR RESIDENCY TESTS The presence requirement can be met more than one way. One83 tracks the 183 day test, the under 90 days in the United States test, the more days in Puerto Rico than the United States test, and the 549 days across three years test. It shows which one you are currently passing, which is still within reach, and how many days of margin you have left in each. WHAT YOU SEE FIRST Open the app and one number answers the question you actually have. Switch it between days left off the island, days of presence so far, and days spent in the United States. A quiet status line tells you whether you are on track, and a seven day strip shows the week at a glance. A CALENDAR THAT EXPLAINS ITSELF Browse the year as a grid or as a running list of every day. Tap any day to see where the answer came from, a flight in your calendar, a location crossing, or your own edit. Change it in one tap. Select many days at once when you need to fix a stretch. Record the time you arrived or left when you want that on the record, without it ever changing the count. PLAN BEFORE YOU BOOK See what a trip costs in island days before you buy the ticket. One83 shows the days you would lose, what is left for the rest of the year, and whether you still clear your target. Save the trip, block the dates in your calendar, or share the plan with whoever books your travel. BUILT FOR AN AUDIT Export a PDF or CSV of your ledger with the source behind every single day, flight event, location crossing, or your own correction. Each report carries a reconciliation line proving the days sum to the year, and a digest that changes if anything in the record changes, so an unedited report can be shown to be unedited. STARTING PART WAY THROUGH THE YEAR Already living on the island? Set your move in date and One83 fills the days from then forward, leaving anything you have already recorded untouched. Connect a calendar and the flights it finds fill in the rest. NOTIFICATIONS THAT STAY QUIET An optional evening reminder appears only on days where nothing at all was recorded, and you can answer it from the notification itself. If your days are already being found for you, you never hear from it. YOUR DATA STAYS ON YOUR PHONE No account. No sign up. No server. No ads. No analytics. No tracking. Your calendar is read on your device and never uploaded, and your location never leaves it. Back up your entire ledger to a file whenever you want and restore it just as easily, and nothing you have already recorded is ever locked away from you. WHO IT IS FOR Act 60 decree holders, anyone working toward bona fide residency in Puerto Rico, and the accountants and advisors who ask them for their day counts every year. One83 is a tracking tool. It does not provide tax or legal advice. Physical presence is one of three bona fide residency tests, and meeting it is not the whole picture.
