Stop finding out your site is down from a customer email. Semaphor puts a traffic-light status board for your websites right on your Home Screen, so one glance answers the question you keep asking: is my site up? Semaphor is built around its widget. Add your websites once, then live on the Home Screen: a clean grid of green, amber, and red dots for every site you care about. Open the app when you want the full dashboard or an on-demand check. The rest of the time, the widget does the watching. WHY SEMAPHOR Most uptime tools assume you want another web dashboard, another account, another subscription. Semaphor assumes you don't. It is a free website uptime checker that lives where you already look two hundred times a day: your Home Screen. PERFECT FOR - Indie makers keeping an eye on their own sites and landing pages - Freelancers and agencies watching client websites - Developers and webmasters watching endpoints and APIs without a tab open - Anyone who just wants to know "is my website down?" at a glance A HOME SCREEN WIDGET, FIRST Pin Semaphor to your Home Screen and every site shows its latest status as a simple traffic light. Green for healthy, amber for slow, red for down. No opening, no scrolling, no login. The widget matches your style with its own light and dark themes. THE APP IS YOUR DASHBOARD Inside the app you add and organize the sites you want to track, see them all on one board, and tap any site for its response time and the latest HTTP result. Hit Ping All to re-check every site at once. Set how often Semaphor re-checks your sites while the app is open. SLOW IS A STATUS TOO Most monitors are binary: up or down. But "up" that takes three seconds to load is losing you visitors. When a site answers slowly, Semaphor shows amber instead of hiding it behind a green checkmark. If you ever wondered "is my website slow?", the answer is now a color. MADE TO FEEL FAST Semaphor is a native app with light and dark themes for both the app and the widget, and crisp haptics as your checks come back. Quick to open, quicker to read. PRIVATE BY DESIGN Semaphor has no account and no sign-up. It only contacts the websites you add, and it stores your list and results on your device. No analytics, no tracking, no data collected about you. Ever. REQUIREMENTS - iPhone and iPad - iOS 26 or later - Free, no account required Put your uptime where you'll actually see it. Add your first site in seconds with Semaphor.
