Message Without Internet

Chat Local uses Bluetooth Low Energy (BLE) to create a decentralized mesh network between nearby phones. Messages travel directly from device to device using Bluetooth — no WiFi, no cell towers, no internet, and no servers involved. When a message needs to reach someone beyond direct Bluetooth range, it automatically hops through other Chat Local users between you, creating a multi-hop mesh relay network.

Offline: sending and receiving messages, mesh relay, delivery confirmations, conversation passwords, message search, chat export, and QR-code invites. None of it touches a network.

Needs a connection: downloading the app in the first place, buying or restoring Pro, and opening a shared invite link (the QR code doesn't). Anything you've already bought keeps working offline for the full period you paid for — so buy before you head somewhere without signal.

Yes. Chat Local is free to download and use with core features including Bluetooth mesh messaging (50-character messages), default encryption, 2 active conversations, and 20-message history. Pro is available as a subscription ($4.99/month or $29.99/year) or a one-time lifetime purchase ($59.99, early adopter discount). Pro unlocks unlimited conversations, 400-character messages, 500-message history, password-protected end-to-end encryption, message search, chat export, themes and backgrounds, user blocking, and faster sending.

Open the conversation, choose Invite People, and show the QR code — they point any standard camera app at it and land in the join screen with the conversation already filled in. This works with no internet or cell service, which is the whole point: it's built for the festival or campsite where nothing else works. They do need Chat Local installed. If they don't have it yet, share the link instead — that opens a page offering the app, so it needs a connection on their end. Invites never carry the conversation password: that is shared separately, in person.

Yes. Chat Local keeps scanning for nearby devices and reconnecting while the app is in the background and the screen is off, so messages keep arriving with your phone pocketed — the normal state at a festival or on a trail. Bluetooth needs to stay enabled, and iOS may deliver background messages slightly less immediately than when the app is open on screen. One thing worth knowing: leave Chat Local running in the background. If you force-quit it, iOS stops delivering Bluetooth events and messages won't arrive until you reopen it.

Chat Local shows a delivery confirmation under your most recent message: sending, sent, or received by the number of nearby devices that acknowledged it. If nobody was in range, it says the message wasn't delivered instead of showing a false success — so you know to move closer, or wait for someone to come into range.

Yes. Locked themes, chat backgrounds and sender colors can be tried inside the app before buying — tap one and you see it applied to your real conversation, then it reverts. There is no free trial of the paid plans. If you would rather not subscribe at all, the one-time lifetime purchase unlocks everything with no recurring charge.

Direct Bluetooth Low Energy range is typically 10-30 meters (35-100 feet) in real-world conditions, up to about 100 meters with clear line of sight, and less through walls or obstacles. However, Chat Local's mesh networking means messages can hop through up to 5 intermediate devices, potentially extending range significantly. The more Chat Local users in an area, the further messages can travel.

No. Chat Local requires zero personal information — no account, no email, no phone number. Just download the app, pick any display name, and start chatting. This makes it ideal for privacy-conscious users who want to communicate without leaving a digital identity trail.

Yes, in two tiers. Every message gets AES-256-GCM encryption by default using keys built into the app — that deters anyone eavesdropping on the airwaves, but treat it as strong obfuscation rather than secrecy. For anything sensitive, create a password-protected conversation (Pro): true end-to-end encryption where only people who know the password can read messages — even devices that relay them can't — and a lock icon marks every message that was actually sent encrypted. One thing that's visible by design: conversation names and sender display names are broadcast to nearby app users (that's how nearby discovery works), so name conversations accordingly.

Yes — this is one of Chat Local's most important use cases. When cell towers are destroyed, power grids are down, or internet infrastructure fails, Chat Local continues to work because it only needs Bluetooth (powered by your phone's battery). Emergency management professionals, preppers, and disaster preparedness advocates use offline mesh messaging as a critical backup communication tool.

Yes, as the reach-your-group layer of a layered comms plan. Chat Local needs no license (unlike ham or GMRS radio), no extra hardware (unlike Meshtastic or goTenna), and no infrastructure — messages travel phone-to-phone over Bluetooth and relay through up to 5 devices, working as long as the phones have battery. It works in airplane mode, which greatly extends battery life in an outage. It is not a way to reach 911 or anyone beyond mesh range — pair it with radio or satellite for distance. See the full grid-down communication guide.

Chat Local is a modern alternative to walkie-talkies with several advantages: it's silent (text-based, not voice), encrypted (walkie-talkies broadcast openly), requires no extra hardware (just your iPhone), supports group conversations, and messages persist so you can read them later. Direct range is shorter than a dedicated radio (typically 10-30 meters), but mesh relay extends it by hopping through other users.

Yes. Turn on airplane mode, then re-enable Bluetooth. Chat Local works perfectly because it only uses Bluetooth — no WiFi or cellular needed. This is ideal for flights, areas where you want to disconnect from the internet, or situations where you need to conserve cellular battery.

No. Chat Local is 100% serverless. Messages are stored only on your local device and transmitted directly between phones over Bluetooth. There are no cloud servers, no data centers, and no third parties that ever see your messages. Uninstalling the app permanently removes all data.

Chat Local is ideal for Burning Man because Black Rock Desert has no reliable cell service. It uses Bluetooth mesh networking to send encrypted messages between iPhones without any internet, cell towers, or extra hardware. Just download before you arrive, pick a name, and your camp can communicate across the playa. The more burners using Chat Local, the further messages travel through the mesh network.

Download Chat Local before the festival. Create a conversation with a name your group agrees on (like your camp name). Everyone with Chat Local in Bluetooth range can send and receive messages — no cell service, WiFi, or internet needed. Works at Burning Man, Coachella, Bonnaroo, Electric Forest, EDC, Lightning in a Bottle, and any event where cell towers are overwhelmed or nonexistent.

Chat Local differentiates with AES-256-GCM encryption on all messages by default (not just opt-in), a custom binary protocol that's 50-60% more efficient than JSON-based alternatives, nearby conversation discovery with message preview, zero account requirements, and a clean freemium model. Unlike Meshtastic, no extra hardware is required. Unlike Briar, it focuses on ease of use with no technical setup needed.
