SmarterNoise also leads on iOS requirement (12.0 vs 17.0). clir Voice's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 6 weeks).

Written reviews complicate that: 75% of SmarterNoise's written reviews are positive against 25% of clir Voice's, so the app with the better star average is not the one people write more warmly about.
