What's New in 6.5.1 • Smoother, more realistic readings — a source now fades cleanly to zero as you move away, with no stuck or bouncing values. • Radiation and chemical-agent readings now ramp up naturally from zero instead of jumping straight to a high value. • Better pickup at the edge of range and through walls or obstructions. • More reliable Bluetooth recovery if scanning gets interrupted mid-session. • Fixed a rare crash on app launch. Train. Respond. Succeed.

Version 6.5 delivers sharper live tracking, a redesigned session library, and more reliable offline drills. • Live tracking — More accurate, responsive real-time location for every participant throughout a session. • Redesigned Replay library — Team sessions and after-action reports are now front and center, sorted newest first, with one tap access to each report. • Reliable offline drills — Record complete sessions with no signal; they sync and merge into a single team replay automatically when you reconnect. • Performance, stability & security — Numerous fixes and hardened data protection across the app. • Improve SOURCE performance and realism

SYGNAL 6.3 adds team scale capabilities: • Auto generated After Action Report (AAR) PDFs for every saved session • Cloud Library — org-wide KML sync across phones, web, and reports • 3D web Replay at replay.sygnalapp.com — photorealistic terrain + time-scrubbable hazards • Sharper live tracking — indoor GPS jitter filtered, map dot steady when still, faster session lock-in • UI polish on host session controls

Introducing Replay — see your sessions play back in photoreal 3D. • 3D Session Replay: scrub the timeline and watch every responder's path. • Cloud Library: automatic team sync of saved sessions — nothing locked to one phone. • Shareable Links: send view-only replays to chiefs and auditors, with optional password and expiry. • Polished UI, faster load, and quieter defaults across the app. Train · Respond · Succeed.

What's new in 6.1: • Smoother offline session join — faster cold start scans • Your own KML, every device — Offline joined participants can now save their own track to the Tracks folder, ready to share • Search in Saved Exports — find any session by name • More reliable export — longer timeouts on long sessions, prevents track loss on manual leave

What's New in 6.0.0 • Refreshed tactical interface — cleaner hazard tiles, balanced session headers, and a unified single accent theme across all modes. • New live trend charts — view every hazard reading over time, drill in by user or by hazard, with high and low O₂ alarm thresholds visible at a glance. • Improved SYGNAL SOURCE performance — faster device pairing, smoother live readings, cleaner scan list.
