Beacon Safe Plus places real automated voice calls to your contacts as the second escalation phase, five minutes after the initial SMS and email. Cairn notifies via SMS and email only — no phone calls.
Same check-in primitive, broader use case: solo travelers, night-shift workers, people living alone, seniors aging in place, gig workers. Cairn is purpose-built for hikers and trip-based.
Set a recurring 12–72 hour interval and forget it. Beacon runs continuously between hikes; Cairn is designed around starting and ending discrete trips.
Beacon Safe never tracks or stores your location. Some users prefer this for privacy. If you want a live trip map for your safety circle, Cairn is the better fit — that's the trade-off.
Both Beacon Safe and Cairn run over cellular and Wi-Fi. If you're going somewhere with no signal — deep backcountry, alpine ridges, slot canyons — you need a satellite device like a Garmin inReach, ZOLEO, or a Personal Locator Beacon (PLB). These apps are best used as a layer on top of a sat communicator for the parts of your trip that have coverage, or on their own for day hikes and front-country trips. Don't bet your life on a phone with no bars.
Pricing
Free: 3 contacts, email only. Plus: 10 contacts, Email + SMS + Voice.
30-day Premium free trial on signup. Premium adds cell-coverage filters, offline maps, and full safety features.
Cairn is cheaper annually ($26.99 vs $199.99). The price gap reflects what each app does: Cairn's hiker focus and Beacon Safe's automated voice-call infrastructure (automated voice calls have real per-minute costs). If you only hike and don't want voice calls, Cairn is the better deal. If you want multi-channel escalation including voice, or you need monthly billing flexibility, Beacon Safe's price reflects what's behind it.
FAQ
Cairn is built specifically for hikers and includes crowdsourced cell-coverage maps, downloadable offline trail maps, and ETA-based overdue detection tied to a planned route. Beacon Safe is a general-purpose check-in app that escalates across four channels — email, SMS, voice call, and push — for hikers, solo travelers, night-shift workers, and anyone living alone. They solve overlapping problems with very different toolboxes.
No. Per Cairn's documentation, overdue notifications go out via SMS text and email to your safety circle. Cairn does not place automated voice phone calls. Beacon Safe Plus places real voice calls to your contacts as the second escalation phase, five minutes after the initial SMS and email, which is useful when contacts have notifications muted or are away from their screens.
No. If you hike where there's no cell coverage, a satellite communicator like a Garmin inReach, ZOLEO, or a Personal Locator Beacon (PLB) is what keeps you alive — those devices use satellite networks that work where phones don't. Beacon Safe is a phone-based check-in app and requires cell service or Wi-Fi to send alerts. It's a complement to a satellite device for the parts of your trip that have coverage, not a replacement.
Yes, especially for day hikes, trail running, and trips where you have intermittent cell coverage. Beacon Safe lets you set a custom check-in interval (12 to 72 hours), and if you don't check in by the deadline, alerts fire automatically from the server — even if your phone is dead. For backcountry trips with no coverage, pair it with a satellite communicator. Cairn is more specialized: its cell-coverage maps and offline trail layers are genuinely useful if hiking is your primary use case.
Cairn is cheaper on an annual basis: Cairn Premium is $26.99/year, while Beacon Safe Plus is $199.99/year. However, Beacon Safe also offers a true free tier (3 contacts, email alerts) and a $19.99/month option for short-term use. Cairn's price reflects its narrow hiker focus; Beacon Safe's price reflects automated voice-call escalation and multi-channel delivery.
Yes. Many hikers run both — Cairn for live trip tracking and trail-aware overdue detection on the hike, Beacon Safe for the daily check-in routine the rest of the week and as a backup multi-channel alert layer. They don't conflict; they have different focal points.
Beacon Safe is live on iOS and Android.
