Airtool Pi vs nChronos

Airtool Pi is an iPhone and iPad utility for remote Wi-Fi packet capture. It connects over SSH to Linux-based sensors or Linux endpoints with compatible adapters, starts a capture using selected settings, and saves a PcapNG file locally. Sensors can be added manually or automatically, including WLAN Pi and Oscium Nomad; version history also names WLAN Pi Go and Hamina Clip, and a Raspberry Pi can serve as a sensor. Capture controls include wireless interface, frequency band, channel, channel width, size limits, and an option to discard data-frame payloads. The App Store listing states support for 2.4, 5, and 6 GHz bands and widths from 20 to 320 MHz. Compatible adapters allow simultaneous capture on up to four channels. Files can be shared with Wireshark or another protocol analyzer. Airtool Pi costs $14.99 USD once and requires iOS or iPadOS 18.6 or later.

nChronos is Colasoft’s application-focused network performance analysis system for medium and large corporate networks. Its client/server design places continuous packet capture, analysis, storage and data mining on a server, while a console displays and analyzes the collected data. The server can receive traffic through a network mirror port or link tap and retain packets for later investigation of network or application problems. Real-time statistics and user-defined alerts show network events as they occur. System or custom reports can be scheduled for hourly, daily, weekly or monthly email delivery. Users can define application and transaction monitoring, with profiles for HTTP, FTP, email and DNS. Packet files can be replayed from Colasoft, libpcap and several vendor formats, including files associated with Wireshark, Ethereal and Tcpdump. Linux server systems and Windows consoles are listed, with browser-based server configuration. Standard specifications allow four logical links, eight capture interfaces and two concurrent server connections.
