The app is design for humidity recorder made by Eyes Blue, you can find the humidity recorder project from the Arduino hub(https://create.arduino.cc/projecthub/eyesblue/humidity-recorder-control-with-android-app-3ccb1e), however, you must have the corresponding device or the app not useful to you.
The humidity recorder could save the humidity data per minute, you can set the interval by the app, get all record data and show as a chart in the app, it consists of humidity sensor, 4 digit clock LED displayer, bluetooth communication module, Real time Clock(RTC) and Arduino controller module, both Android app and Arduino code are stable, I made 3 device and work almost 1 year until now, both Android app and Arduino project are open source, it may safe someone in somewhere.
