What's New in bmLogger
13.8.5
August 5, 2026
• Faster, more reliable downloads — connections establish quicker, the progress bar tracks the real transfer, and large logs no longer freeze the app while they are saved. • Alerts reconnect on their own — when a logger goes out of range and comes back, the app re-establishes alert monitoring automatically, even from the background, so you don't have to open the app. • Focus on a single reading — tap any measurement badge above the chart to expand just that reading, and tap "All" to return to the combined view. • Numerous stability improvements and bug fixes across downloading, alerts, and device history.
