A narrative radio survival game. Atmospheric. Quiet. The threat is what you do with what you hear. Something happened. The grid is mostly dark. You're alone at Station Kilo. The shortwave still works. Most of the band is static. Occasionally, somewhere between 34.1 and 112.7 MHz, a voice cuts through. Elias, alone on a property northeast. June, holed up south of him, watching his generator light. A government broadcast on 91.1. A radio DJ still talking into the dark. A coordinator offering a slot at a place called Cedar Ridge. Some of them will help you. Some of them are lying. One of them knows what really happened. WHAT IT IS • A real-time narrative game paced like a real radio. Responses can take minutes or hours. The notification will reach you. • 13 distinct characters across 11 frequencies, plus a hidden hijack mechanic on 88.1 if you figure out how it works. • Every choice ripples. Sharing HAVEN coordinates with June pulls Marcus into the world. Helping Elias bleed the fuel line unlocks the path to 88.1. Betraying anyone to the coordinator severs everyone. • A journal that fills itself as you uncover things. • Twenty hidden side stories on the dark frequencies. Type whatever you want to say: your words decide how each one ends, and every playthrough tunes in a different one. • Game Center achievements, and a shareable card when your station finally goes dark. WHAT IT ISN'T • A chat app. You will not reply in real-time. Signals are sparse on purpose. • An action game. Nobody's coming for you. The threat is what you decide to do with what you hear. • A game you can rush. You can play in 5-minute windows over a week. That's the design. ACCESSIBLE BY DESIGN Signal Lost works with VoiceOver. Every screen is labeled, and the tuning dial is an adjustable control you can sweep with a swipe or jump between marked frequencies. The station's text follows your Dynamic Type size. Free. No ads. The whole story is free. If the station keeps you company, there's an optional "Support the Station" tip jar in Settings. Any tip unlocks amber and white phosphor colors as a thank-you. Built by one person. Headphones recommended.

Verdict
The clearest difference is in-app purchases: SONAR Deep Dive at none against Signal Lost's 3. SONAR Deep Dive also leads on update cadence (every 2 days vs every 2 weeks) and iOS requirement (13.0 vs 17.0). Signal Lost's advantage is ads (none vs shown). On price and device support there is nothing between them.
