Question 1

No signal during a wildfire, earthquake, or typhoon — can I still message?

Accepted Answer

Yes. SignalAir Rescue is an offline communication app that doesn't rely on cell towers or the internet. When networks go down, it uses Wi-Fi Direct and Bluetooth to connect phones directly, letting people within roughly 50–500 meters send messages and distress signals.

Question 2

How do I let family know where I am during an evacuation?

Accepted Answer

Use one of four one-tap status alerts (I'm Safe / Need Medical / Need Supplies / Danger Warning) plus text messages. The app shows a fuzzy relative position (within ~100–500 m) to help nearby family or rescuers locate you.

Question 3

How is this different from regular chat apps that need internet?

Accepted Answer

The key difference: it works offline. Most messaging apps depend on internet and cloud servers. SignalAir Rescue uses P2P offline mesh networking, so you stay connected even when the network is completely down.

Question 4

Do I need to buy extra hardware like a walkie-talkie or radio?

Accepted Answer

No. All you need is an iPhone or iPad — no extra devices required. Just install the app, enable Wi-Fi and Bluetooth, and you're ready.

Question 5

Are messages secure? Can they be intercepted?

Accepted Answer

Messages are end-to-end encrypted with ChaCha20-Poly1305, readable only by the sender and recipient. They never pass through a central server, significantly reducing interception and leakage risk.

Question 6

Does the app collect personal data?

Accepted Answer

No identifiable data is collected — no name, phone number, email, or IP address. Location is processed only as a fuzzy grid for relative distance calculation; precise coordinates are never stored.

Question 7

What other situations is it useful for besides emergencies?

Accepted Answer

Great for concerts, festivals, New Year events, hiking, camping, remote areas, power outages, and overloaded cell towers. Also ideal for privacy-conscious users who prefer offline, cloud-free daily messaging.

Question 8

What's the difference between Free and Lifetime Pro?

Accepted Answer

Free includes core features (offline messaging, emergency signals, end-to-end encryption) with a 50 messages/day chat limit. Lifetime Pro is a one-time unlock for unlimited chat, multiplayer Bingo Game Room, leaderboards, and all future features (see App Store for current pricing).

Question 9

Can it replace emergency services calls?

Accepted Answer

No. In life-threatening situations, always call official emergency numbers first. This app is a backup communication tool for when official channels are unavailable or overwhelmed.

Question 10

What languages are supported? Where do I download it?

Accepted Answer

7 languages: Traditional Chinese, English, Japanese, Hindi, Spanish, Português (Brasil), and Bahasa Indonesia. Free on the iOS App Store — no account registration needed.

Question 11

Can firefighters, rescue teams, or community disaster volunteers use it?

Accepted Answer

Yes. Anyone can download it for free from the App Store. Once opened on-site, devices automatically form a mesh network — no extra setup or vendor support needed. This app is a personal backup communication tool, not an institutional deployment solution. Usage is identical to that of any individual user.

Question 12

What is the whitelist feature and how does it work?

Accepted Answer

Tap any contact to add them to your whitelist and set them as a priority messaging target. There's no limit to how many contacts you can whitelist, though iPhone hardware allows a maximum of 8 simultaneous device connections. We recommend adding family members or teammates to your whitelist so they stay reachable first when it matters most.
