goTenna Pro vs HeaderCheck

The goTenna Pro app is a tactical situational awareness application that pairs with goTenna Pro and goTenna Pro X2 mesh networking radio devices to enable mission-critical communications completely independent of traditional cell, Wi-Fi, or satellite connectivity. Users can download the goTenna Pro app to any iOS device, pair with a goTenna Pro or goTenna Pro X2 tactical radio, and then use the mobile device to communicate critical information like near real-time locations, share map markings, and send text messages while 100% off-grid. The app supports full interoperability with ATAK and the goTenna Android goTenna Pro app for seamless cross-platform mission coordination. goTenna Pro tactical radios have a 5W, tunable UHF/VHF output that can transmit critical data from your iOS device and also automatically act as relays that securely and anonymously “hop” messages across up to 6 devices to extend range. Key Features - Send & receive text-based messages - Automatic blue force tracking - Customizable map markers for emergencies, dangers, and objectives - Routes, perimeters, geofencing, and shape drawing tools - Individual & group messaging - Broadcasts to anyone within range on your network - Interoperability with iOS/Android goTenna Pro apps, ATAK plugin v2.2.50, and iTAK v2.10.1 - Ability to import offline maps (.sqlite files) to display custom maps on the field - Send/receive standard 2525B tactical markers

HeaderCheck turns raw email authentication headers into clear SPF, DKIM, and DMARC verdicts, entirely on your iPhone or iPad. Paste headers, open a sample, or import an .eml (Pro). No account. No upload. Analysis never leaves this device. WHY IT MATTERS Phishing often fakes the From line. Authentication results in the headers show whether the sending domain actually passed SPF, DKIM, and DMARC. HeaderCheck makes those fields readable. HOW TO USE • Paste raw headers from “Show original” / “View source” • Or forward as attachment and open the .eml (Pro) • Read Pass / Fail / Softfail badges and heuristic flags • Copy a summary or export a PDF (Pro) FREE Paste analysis, badges, copy summary, and a rolling history of your latest analyses. PRO (one-time) PDF export, unlimited history, and .eml import / Share Sheet open. HeaderCheck reports what is in the headers you provide. It does not guarantee a message is safe or malicious, and it is not legal or forensic advice.
