iPhone

Turn your phone into a motion detector alarm. Point, arm, and Vigil sounds off the moment a person or car appears — now zoom in to watch a far door or gate. Free trial. Vigil turns the phone you already own into a motion-triggered guard. Point the camera at a doorway, hallway, or your gear. Tap Arm. Vigil keeps watch — and the instant a PERSON or a MOVING VEHICLE comes into view, it sounds a loud alarm. Turn on Sound and Vigil listens too — footsteps or a car pulling up trip the alarm even out of frame, while everyday noise like birds is filtered out. Built for people who can't afford to miss someone coming. • NO HARDWARE — it's the camera already in your pocket • 10-SECOND SETUP — point, arm, done • LOUD ALARM — overrides the silent switch to wake you and warn them off • SMART DETECTION — spots people, vehicles, and bicycles, ignores parked cars and background motion, so fewer false alarms • WATCH ZONE — draw a box on screen to watch only the area that matters • ZOOM TO REACH FARTHER — a zoom slider to focus on a distant doorway, gate, or hallway, plus adjustable sensitivity from Low to Extreme, so Vigil can catch someone from across a large space • SEND FEEDBACK — request a feature or report a bug right from Settings; Vigil is built by one person and your feedback shapes what comes next • RUNS FOR HOURS — battery- and heat-smart, so it can stand guard on long watches; the screen dims while watching and lights up instantly on an alarm • LIVE TARGET LOCK — a targeting reticle frames what Vigil sees on screen, in real time • SOUND DETECTION (optional) — listens for footsteps or a car pulling up even off-camera, and ignores everyday noise like birds • PRIVATE — nothing is recorded, nothing is uploaded; it all runs on your device • FREE TRIAL — try it free, then $19.99/year Tip: wear a Bluetooth earbud and the alarm plays only in your ear — a discreet, silent alert just for you, so you know someone's coming without tipping them off. Made for solo security guards on long shifts, lone night-shift workers, travelers napping in hostels or tents, and anyone who wants to step away from their stuff and know if someone comes near. Note: Vigil must stay open with the screen on while armed — iOS pauses the camera in the background. Important: Vigil is a personal awareness aid, not a professional or monitored security system or life-safety device, and it cannot guarantee detection. Don't rely on it as your only safeguard or in emergencies — for real safety needs, use professional security and your local emergency services. Vigil Pro is an auto-renewable subscription (3-day free trial, then $19.99/year or $6.99/month), or a one-time Lifetime purchase. Payment is charged to your Apple ID; a subscription auto-renews unless cancelled at least 24 hours before the period ends; manage or cancel in your App Store account settings.

  • This app hasn’t received enough ratings or reviews to display an overview.

Now you can reach farther — and tell us what to build next. • ZOOM TO WATCH FARTHER — Use the new zoom slider to aim Vigil at a distant doorway, gate, or hallway. A far person or car fills more of the frame, so the alarm can trip from across a larger space. • REQUEST FEATURES & REPORT BUGS — A new Feedback section in Settings sends your ideas and bug reports straight to the developer. Vigil is built by one person, and your feedback shapes what comes next. • POLISH — Wording and reliability refinements throughout. Point it, arm it, and Vigil keeps watch. A rating genuinely helps a solo developer — thank you.
