The clearest difference is ads: Rhythm at none against WeightFast's shown. Rhythm also leads on monetization model (free vs ad-supported). WeightFast's advantage is review sentiment (100% vs 89%) and iOS requirement (14.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.
