DirectTalk 2

• Ensure that you have Wi-Fi enabled within system settings to connect to devices. Internet or Wi-Fi connection is not necessary, the app just needs to access the Wi-Fi radio.

• Ensure you have Microphone and Local Network access allowed to use the app. For best background use, also allow access to send Notifications.

• The app will automatically decide the protocols to use to directly connect to the other device.

• When operating over peer-to-peer connections, good performance is maintained when all devices are in a 10 meter range. Otherwise, you will be warned if your audio message does not seem to be transmitting correctly. When this happens, audio may cut in and out, and you might experience delays or repeated failing connections.

• To operate over WLAN connections, ensure all devices are connected to the same Wi-Fi network or Wi-Fi networks sharing the same Local Area Network. The app should automatically switch over to using LAN as long as the Wi-Fi access points and routers do not block Bonjour discovery (multicast DNS) and inter-device communication.

• Hands-free usage is supported via Voice Activated Exchange (VOX). Voice Isolation is recommended. Configure the microphone to use this activation and processing mode in settings or via the quick toggles available on the homepage.

• Earphone/headphone/earbud buttons to control the walkie talkie is supported as long as you allow usage of the system call UI on iOS or iPadOS 17 and later. Check your system settings to see the number of presses required. These buttons may only toggle the microphone on and off and do not support Push-to-Talk.

• Using third-party push-to-talk hardware is not officially verified or supported. Use the free-trial to test whether your hardware is compatible.

• Background operations may fail in certain extreme circumstances due to iOS and iPadOS restrictions on background tasks. To ensure you get notified whenever the app unexpectedly fails in the background, enable notifications.

• Free-trials are limited to 15 minutes per session. You can launch a new session after one ends, which resets the timer, for as many times as you wish. This allows you to adequately test all possible scenarios you’re interested in before purchasing. Extended session trial lengths are available via customer support.

• The app does automatic discovery over Bonjour of nearby devices. This requires multicast DNS (mDNS) to be allowed, if you want to connect via WLAN. If you wish to connect to a device manually, you may specify the network address (IP or hostname) and port in connections page. You must still be on the same channel (and secret, if set) to connect.

• In very specific situations, the app could connect via the Internet, despite its design for local proximity usage. This is possible if you manually specified an address on the Internet that happens to have the app running, or if you are using a Virtual Private Network (VPN) service with a private LAN, and that forwards Bonjour (mDNS) packets to all devices on the same VPN.

• The app may believe a connection is operating over the Internet when it isn’t, and vice versa. It does this by simply checking if the IP address is within the local network range - this detection fails if your network is misconfigured, or you’re connected to a private LAN routed by a VPN via the Internet.

• The app internally uses Apple Wireless Direct Link (AWDL) for peer-to-peer connections. This technology is similar to Wi-Fi Direct, but is proprietary and only officially usable on Apple devices. Using AWDL can potentially degrade performance for other Wi-Fi traffic. As such, the app may try to use WLAN when it is feasible to do so, even in close proximity.

• The app currently transmits at up to 250kB/s (2Mbps) per connection. This means network traffic increases with more devices, and may overwhelm nearby Wi-Fi networks or your LAN infrastructure if many people use the app on the same channel. Support for multicast and compression may come in the future to mitigate this.

• Bulk purchases may not yet be available. Businesses looking to use this app for commercial purposes may contact support to get notified when a business license or bulk-purchase is available. Please ensure to test the app using the free trial, and confirm that it meets your requirements and does not overwhelm your network.

New users get a free trial where each session is limited to 15 minutes. You can launch a new session after one ends, which resets the timer, for as many times as you wish.

Once you’re satisfied that DirectTalk suits your use case, just make a small one-time purchase to get the full license - no subscriptions!

PSA:

If you wish to test a use case that requires a session length longer than 15 minutes before your purchase, please contact customer support.

Users of the previous version of the app may claim a discounted license upgrade by keeping the old version installed during the purchase process. Having such previous license also automatically grants access to an extended 30 minute per-session limit for free trial.
