The app provides information on over 200 bird species found in Hong Kong, including over 600 photographs and 50 bird calls. Users can search and filter bird data by various criteria, with support for English and Traditional Chinese.
The app calculates RC charging and RC filter circuits. It finds component values, voltage at time t, and cutoff frequency, and saves data to CSV files.
The app converts dates between Gregorian, Buddhist, Chinese, Coptic, Ethiopic, Hebrew, Indian National, Islamic, Japanese, Persian, and Republic of China calendars. It uses macOS’s built-in capabilities for these conversions.
