## Version history (last 5 releases)

### 13.8.5 — 2026-08-05

• 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.
