The call

The clearest difference is in-app purchases: Syllable at none against DecoEcho's 1. Syllable also leads on iOS requirement (16.6 vs 18.0). DecoEcho's advantage is ads (none vs shown) and update cadence (monthly vs every 5 months). On price and device support there is nothing between them.
