Verdict
The clearest difference is in-app purchases: Tangram at none against Zener Wave's 1. Tangram also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.6). Zener Wave's advantage is ads (none vs shown) and update cadence (every 2 months vs every 6 months). On price there is nothing between them.
