Signal Beacon sends and reads messages by light, so you can reach someone when there is no cell signal, no Wi-Fi, and no time. BROADCAST • Flashlight: your phone's flashlight blinks your message in Morse code. Anyone with Signal Beacon, or who knows Morse, can read it from far away with a clear line of sight. • Screen code: show a code on your screen for a phone held up close. Send longer messages, your location, even a photo. • Quick messages for SOS, need help, injured, lost, I'm OK and need water. Add your coordinates so a rescuer knows where you are. • The screen goes dark while it signals to save battery. SCAN • Point the camera at a blinking light or a screen code to read it. • Tap the light to lock on. Automatic sensitivity adjusts to day and night, and the reader holds on through a shaky hand. • Received messages show the distance and direction to the sender. • Turn any message into a short video clip to share, with real camera footage or a clean light animation. TALK • A two-way conversation over light between two phones, up to line of sight. One phone calls, the other answers, and each line you send is confirmed with a receipt. MADE FOR THE FIELD • Works with no signal. Nothing is uploaded; the app has no accounts, no ads and no tracking. • Red night mode protects your night vision. • Plain, rugged controls you can use with cold hands.

A call now carries on if the screen blips, and a phone no longer answers twice in a row, which could make it miss the other phone's reply. Talk runs the camera at 120 fps so phones stay cooler on longer calls. The full-screen camera's buttons now sit clear of the status bar. ### 1.1.1 — 2026-10-03 Fixes the shared clips: a clip of a message you scanned, or of a line the other phone sent in Talk, now shows the whole message from the first flash to the last, with each letter appearing as it is read, instead of cutting off most of it. ### 1.1 — 2026-10-03 New Learn tab: a Morse-by-light teaching game with lessons, a daily challenge, a speed ladder, and Game Center leaderboards and achievements. Scan now reads imperfect hand-sent Morse much better: it follows speed changes, tries other readings and picks the one that makes real words, and marks unsure letters with a question mark. Also: automatic sensitivity in Scan and Talk, steadier reading with a hand-held phone, a brighter night mode with a camera picture you can actually see, shareable clips of messages you receive, an Invite screen, and a flashing-light safety notice at first launch. ### 1.0 — 2026-10-02 No release notes. ## Apps similar to Signal Beacon | App | Rating | Price | Category | | --- | --- | --- | --- | | [SweetSpot Signal Finder](https://appshunter.io/ios/app/sweetspot-signal-finder/id6787468095) | — | Free | Utilities | | [TrueSignal](https://appshunter.io/ios/app/truesignal/id6760624783) | 5.0 (5) | Free | Utilities | | [SPARQ AI](https://appshunter.io/ios/app/sparq-ai/id6469515871) | 4.7 (371) | Free | Utilities | | [DashPass Pickup](https://appshunter.io/ios/app/dashpass-pickup/id1520321958) | 3.1 (167) | Free | Utilities | | [Speedometer ..](https://appshunter.io/ios/app/speedometer/id1459737793) | 4.4 (4,684) | Free | Utilities | | [Flashcards maker - Easy to use](https://appshunter.io/ios/app/flashcards-maker-easy-to-use/id6443744187) | 4.7 (877) | Free | Utilities | ## More apps by JUSTIN ALAN ELBERT - [framily: find free time](https://appshunter.io/ios/app/framily-find-free-time/id6813910429) All apps by JUSTIN ALAN ELBERT: https://appshunter.io/developer/6813910431 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
