I'm looking to obtain the APK file for the ultrasound device we discussed earlier. It's crucial for me to integrate the software with our existing systems, and having access to the file would really help streamline our operations. Could you please provide the APK file at your earliest convenience? If there are any specific steps or requirements I need to follow to get it, just let me know. Thanks in advance for your assistance!
