The "noise function" mutes the noise during actual communication. "Fuzzy keying" is a function that reproduces a fluctuating signal like a vertical key that a person hits. Even if there is a little fluctuation, the reception difficulty will go up sharply. Supported the QSB function.

Verdict
The clearest difference is update cadence: WabunMorsePro at every 5 weeks against SignalLearning's every 19 months. WabunMorsePro also leads on iOS requirement (12.0 vs 15.6). SignalLearning's advantage is price ($0.99 vs $2.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
