## What is Spradow Logger?

Spradow Logger allows users to connect to up to 4 compatible local pressure and/or temperature sensors to view and record live data and share saved data directly from their mobile device.


## Version history (last 5 releases)

### 4.4.4 — 2026-06-18

Small bug fixed where alarms could cause an endless loop of file saves.

### 4.4.0+2 — 2026-04-22

Differential pressure channels can be given a custom name and colour, edited after creation, and removed. Your configuration is saved and automatically restored the next time you open the app with the same sensors connected.

Independent Y axis on the graph, preventing a wide-range sensor (such as temperature) from compressing the graph line of a narrow-range one (such as pressure).

Sensor tiles in the live screen can now be tapped to open the sensor settings (name, unit, colour) directly, without having to navigate back to the devices screen.

PDF report exports as well as CSV, which include geographical location.

Improvements and bug fixes

- The Live button is now always visible on the devices screen, greyed out when no sensors are connected, so it's clear the feature exists
- The record button flashes red on the graph screen while a recording is in progress
- After completing sensor setup, the app now automatically connects to the sensor
- Tapping Cancel during a recording now asks for confirmation before discarding the data
- Pressure values below zero (e.g. -0.5 bar) now display correctly on the graph — previously the graph line would never go below 0

### 4.2.0 — 2026-03-20

Stability and performance updates.

### 4.1.0 — 2026-03-10

Minor changes to look and feel to improve contrast.

### 4.0 — 2026-03-04

Improved user experience.
