- Added battery life estimation (remaining days of operation) - Warmup and sensor disconnection are now shown as warning banners - Measurement settings reorganized into 3 groups for clarity - Internal memory data download now works over BLE - Improved connection stability

Fixed an issue where older M-Logger units (without the CO2 sensor) could not load or save measurement settings, and could not display live measurement values Reconnecting to an M-Logger is now about 2 seconds faster

- Refreshed the clothing and activity selection icons from photographs to a consistent illustration style - Improved the device settings screen with clearer section headings and button labels - Unified the share / delete swipe colors on the data files screen across iOS and Android - Fixed an issue where the measurement start time appeared in red immediately after connecting - Added a link to the official website (mlogger.jp) in the footer of the home screen - Various minor UI refinements

Fixed a bug causing duplicate records due to event cancellation errors during measurement data reception

Fixed crash bug related to iOS 26's new rendering method.

Added CO2 sensor logging functionality

Added initialization processing for the CO2 sensor.

Bug fixes for CO2 measurement function, bug fixes for logging data viewing function

Supports CO2 sensor connection.

Change data sharing method to temporary files instead of text

Deleted unused entries for coefficients in the velocity characteristic equation.

Added the function to display initial values in velocity calibration panel.

A memo function has been added for when measurements are taken.

Shake event bug fixes

DigiIoT version update, bug fix for screen transition during wind speed calibration

Fixed a bug that caused the program to crash when there was a large amount of measurement data.

Expressing the velocity characteristic coefficient as a quadratic equation

Improved velocity calibration function, added log recording function, added functions related to CO2 level measuring.

Default file names for data sharing have been changed, and WBGT can be displayed.

Changed design of logging start button.

When the wind speed exceeds 1.0 m/s, display 'OOR'. Avoid the bug where the measurement time interval turns white in dark mode.

Extend data copy function to data sharing function.

Visualized RSSI

Added warning when stopping measurement.

Fixed a bug related to display in dark mode.
