Something just moved. Or did it? Ectavo turns your iPhone into a handheld paranormal investigation kit: a spirit radar, an EMF-style meter, and a full session log, all built for one purpose. Making the dark a lot more interesting. Point your phone. Sweep the room. Watch the needle jump. SPIRIT RADAR A live 360-degree sweep that maps activity around you in real time. Contacts appear as blips with distance and bearing, so you always know which corner to check next. EMF-STYLE METER The classic ghost-hunting readout, reimagined for your phone. The meter climbs, the handset buzzes, and the screen floods red when a reading spikes. SIGNAL AND WORD LOG Every session is recorded with timestamps, readings, and captured words, so you can scroll back through the night and argue about what actually happened. NIGHT MODE A dark, low-glare interface built for basements, attics, and 2 a.m. hallways. The red-light theme keeps your eyes adjusted to the dark. SESSION REPLAY Save each investigation, name the location, and share the results with whoever dared you to go in first. BUILT FOR THE MOMENT Instant start, no setup and no account Haptic feedback you feel in your hands Works anywhere: old houses, campsites, hotel rooms, your own hallway Designed for solo scares and group dares alike PERFECT FOR Halloween night. Sleepovers. Road trips. Campfire stories that need a prop. Convincing your friend the attic is a bad idea. Long, quiet evenings that could use a little dread. PLEASE READ THIS PART Ectavo is an entertainment app. It does not detect ghosts, spirits, or paranormal activity of any kind, and it makes no claim to. Every blip, reading, word, and alert is simulated for fun. Enjoy it as the toy it is, and please don't use it to make decisions about real places, real people, or anything that actually matters. Turn the lights off. Turn the volume up. See what happens. Some features require a premium subscription, available through in-app purchases.
