What’s new
Version 1.0.74 · Updated September 25, 2025
Improvements from Ver 1.0.73 to 1.0.74: - Minor improvement on data streaming to DB. Improvements from Ver 1.0.70 to 1.0.73: - Added Eco Mode to reduce the real-time logging screen refresh rate. This helps lower GPU usage and prevents overheating or crashes on entry-level smartphones. - Disabled battery optimization to enhance app reliability when running in the background. - Database size limited to 20 GB to ensure stable performance and efficient resource usage. Improvements from Ver 1.0.65 to 1.0.70: - Graphic Display Smoothness: Improved UI performance by displaying one page at a time without retrospective rendering to prevent overload. The application's sampling rate remains unchanged, even during extended logging periods. - BLE Connection Stability: Resolved an issue with BLE disconnections by debugging a low-level infinite loop in the BLE communication layer. - Reconnection Reliability: Improved reconnection behavior by addressing the same low-level BLE loop issue as above. - Real-Time Logging and Data Saving: Each reading is now written directly to the database immediately upon receipt from the meter, without using RAM buffering. This enhances both performance and reliability. - Data Loss Prevention: As readings are saved directly to the database file in real time, data remains intact even if the phone powers off unexpectedly during logging. Data loss is effectively prevented. - Data Saving Completion: Data saving now completes automatically once logging ends—no additional processing is required afterward. - CSV File Format Consistency: Improved consistency in the CSV data file format for better compatibility and ease of use.
