ServiceArchive

ServiceArchive Pro keeps the documents and the dates that carry weight across years of VA disability claims. We built ServiceArchive because we kept hearing the same story from veterans: a PACT Act denial eleven months ago, a sleep apnea diagnosis ten years post-discharge, a C&P exam in two weeks - and the records that would prove service connection are scattered across email, a shoebox, and a memory that's working against the timeline. ServiceArchive is the cabinet that keeps them, on this iPhone, for as long as the claim cycle runs. Built for veterans navigating PACT Act burn-pit denials, Camp Lejeune 1953-1987, Agent Orange Vietnam-era, Gulf War presumption, and the September 2025 VA OIG report finding 61% of toxic-exposure denials potentially erroneous.

Cairn counts down to the days you're waiting for, and counts up from the days you don't want to forget. Give it a date. It answers in days — 124 days to go, or 1,024 days since. Everything else gets out of the way. COUNTDOWN AND COUNT-UP, ONE MODEL • Days to go for anything ahead: a holiday, a trip, an exam, a due date • Days since anything behind: an anniversary, a baby's birth, the day you quit • Turn on minute precision when the hour matters — "3 days 4 hours", with seconds only in the final hour • Repeat yearly, monthly, weekly, every N days, or by the lunar calendar • Every event carries its own time zone, so flying across the world never shifts the number • Count only working days when a countdown is about business days • A date calculator for the days between two dates, or a date N days away — save the answer as an event • Pick up dates from a screenshot, a photo or a bit of text, and start a new event already filled in SEE WHERE IT STANDS • A countdown bar reads like a battery gauge: solid is what's left, full to empty • A count-up grid fills one square at a time, a day at a time • Milestones at 100, 365, 520, 1,000 and 1,314 days, marked right on the track • Ring, milestone track or heat grid — pick one per event, or just keep the number • A year view lays out all twelve months at once, so you can see which one is crowded; a month view lays them out day by day • Yearly events show which anniversary it is, and the day a countdown reaches zero gets a small celebration REMINDERS THAT ARRIVE ON TIME • Several reminders per event: days, weeks or months ahead, at the hour you choose • A daily digest each morning for what's today and what's this week • Live Activity and Dynamic Island for the last 24 hours • Time-sensitive delivery for the dates that shouldn't wait behind a Focus EVERYWHERE YOU LOOK • Home Screen widgets in small, medium and large: one event, a list, or a chart • Lock Screen widgets — inline, circular and rectangular — each pointed at the event you choose • An Apple Watch app and complications: circular, rectangular, inline and corner • A Control Center control for a new countdown in one tap • Ask Siri how long until anything, or find an event right from Spotlight • Share an event with family or friends: change the date and it changes for them too YOURS, AND ONLY YOURS • No account. Nothing to sign up for. • Syncs across iPhone, iPad and Mac through your own iCloud, and mirrors to Apple Watch from your iPhone • Import dates from Calendar and birthdays from Contacts — read only, never written back • Export everything to a single JSON file and import it back whenever you like; local snapshots and Recently Deleted bring back what you removed by mistake • App Lock asks for Face ID, Touch ID or your passcode when you come back • Cover photos with automatic tinting, six muted themes, categories, pinning, archiving and a share card • English, Simplified and Traditional Chinese, Japanese, Korean, German, Spanish and Brazilian Portuguese — dates and month names included Cairn is a one-time purchase. No in-app purchases, no subscription, no ads, no tracking. A cairn is the pile of stones a trail keeps stacking to mark the way — one for every stretch you have walked.
