# Vigil: Market Crash Alerts — Why the market moved today > Why the market moved today (iPhone/iPad app by Keyao Zhu.) - Source: https://appshunter.io/ios/app/vigil-market-crash-alerts/id6816852936 (this page in markdown: same URL + `.md`) - Developer: [Keyao Zhu](https://appshunter.io/developer/6794569886) - Category: Finance, News - Price: Free with in-app purchases - Age rating: 4+ - Requires: iOS 16.4 · 49 MB - Languages: American English - Released: 2026-10-13 - Data updated: 2026-11-10 ## What is Vigil? Vigil is the calm way to check the US stock market. Instead of red numbers next to a sell button, you get context: what the S&P 500 did today, how ordinary that was against every trading day since 1950, and why it moved, with sources. When something genuinely unusual happens (about six times a year), you get one calm alert, with the plan you wrote in advance. EVERY DAY, IN CONTEXT • Today's move and how ordinary it was: "An ordinary day: 58% of days since 1950 moved more." • Why it moved: a short summary of what the news coverage said, with links to the sources. Written by AI after the close and labeled as reporting, not cause and effect. • This week and this month so far, the distance from the record high, and a fear-gauge band • Your own money, free: enter one rough total or your exact funds and see today's move in your currency QUIET UNTIL IT MATTERS • Alerts only on statistically unusual closes: a big down day, a new level below the record, a fear-gauge spike, a full recovery. About 6 a year since 1990, more in a crisis, none in quiet years. • Each alert opens with the plan you wrote, then what happened, how every comparable decline since 1950 played out (worst case included), and what it means for your funds • Vigil's watch: how many closes Vigil has read for you, and how far today was from each alert line • Optional quiet notes: a one-line Friday note on the week and a monthly report. No sound. YOUR PLAN, WRITTEN WHILE IT'S CALM Write down what you will do if the market falls 10%, 20% or 30%, next to what history says about that level. Vigil shows it back to you, word for word, when the market gets there. On a rough day, note how it feels in one tap: next time, Vigil shows you what you noted (it stays on your phone). WIDGETS The market's weather and the S&P 500's day on your home screen and lock screen (iPhone), without opening the app. ALSO • Sell on paper: when you feel like selling, record the sale without touching your money, and Vigil shows what holding did instead, after a week, a month and three months • Headline check: paste a headline or a link and see how much weight it deserves for a long-term investor • Blind crash test: relive a real past decline week by week, without knowing which one • US market only (S&P 500). Funds listed elsewhere are counted by how closely they move with it • English, 中文, Français, Español • No ads, no trading, no stock tips, no predictions VIGIL PREMIUM (optional) • Before you sell: on a falling day, your plan, what selling now and buying back at the high would cost you, and how every past decline at that depth went, with a 72-hour pause and a reminder • Your money in every past decline of 15% or more since 1950 • A plan for every level: up to 6 plans • A mid-session notice if the S&P 500 is down 4% or more (15-minute delayed) • How a decline unfolded: every day that moved it, with what reports said • Every past alert since 1990, with what came next • 60 headline checks a month (free: 2) • When the market starts to fall, Premium turns on free for 14 days.
