Verdict
The clearest difference is in-app purchases: Mouth Detection at none against Tone Generator's 1. Mouth Detection also leads on update cadence (fortnightly vs every 5 months). Tone Generator's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
