Just one feature: Chime on the hour
Freq.
Read full descriptionHide full description
Freq shows you the frequency of sounds around you. Point your mic at something and see the frequency. If it's a musical note, you'll see which one and how sharp or flat it is. There's a spectrum view to see all the frequencies at once, and a waveform that shows the actual sound. You can adjust how precise the analysis is - faster updates or more accuracy.

Verdict
The clearest difference is price: On the hour at Free against Freq.'s $0.99. On the hour also leads on update cadence (weekly vs fortnightly) and iOS requirement (15.1 vs 26.0). On ads, in-app purchases and device support there is nothing between them.
