Verdict

The call

The clearest difference is monetization model: WaveFast at free against Ayuno's freemium. WaveFast also leads on iOS requirement (17.6 vs 26.0). Ayuno's advantage is update cadence (every 4 days vs every 3 weeks). On price, rating, ratings volume and ads there is nothing between them.
