Detective Pro is paid version without ads. Detective is a tool that allows you to record voices and sounds around you. It won't record silence or white noise. Basically you can turn on Detective, start capturing, leave the phone as it is. As long as the phone has battery it will record sounds as described above...

With Detective you can:
- Record voices if any depending on microphone sensitivity.
- Adjust microphone sensitivity.
- Upload your recordings to cloud and then download to your PC.
- Set timer to delay the start of recording.
- Password protect your recordings to make sure nobody else can access your recording even if they have the phone.
- App runs under the lock so that you can start the recording and lock the phone and it keeps recording at the background ;)
- The closer is the phone to the sound sources the better quality you will get.
- Make sure you keep an eye on battery. It consumes 10%-15% per hour depending on the microphone sensitivity and sound sources around the phone.
- Absolutely no ads on fully paid, non-trial version...

For example you can use Detective in the following situations:
- When hiking, you can use detective to sounds from nature like animals,
- If you hear mysterious sounds coming around the house you can use Detective to capture them as evidence.
