You can use table to do side-by-side comparison of the two APPs, e.g. developer, technical specifications, popularity, etc.
You can do some preliminary measurements on sound / noise using the two APPs (please describe how you do that), screenshot your result, and include the pictures in the report.
I would like you also discuss what feature(s) of the APP can be further improved (exercise your critical thinking skills).

Noise Meter APP Comparison
The Environmental Protection Agency recommends that the most effective way of protecting your hearing is limiting the level of noise to about 70 decibels (dB). The hearing experts also assert that exposure to continued noise greater than 85 dB will ultimately cause harm to the individual. In order to be aware about the sound level that is harmful for your hearing, you might consider using the noise meter apps, which indicates the amount of noise that you are exposed to. The apps can be downloaded on the phone. Studies show that hearing lost ranks as the fourth top cause of disability in the world, and it is still expected to get worse.
