Filterjam is a multi-band resonant filter delivering weird ringmod-like filtered sounds. The input signal is divided into 4 bands that are then summed or multiplied together according to the selected mode. Filterjam can be very harsh or gentle, it can add brightness or depth to synth sounds, but it can also completely mangle acoustic sources.

Verdict
The clearest difference is in-app purchases: Filterjam at none against PolyIvoks Filter's 1. Filterjam also leads on rating (5.0 vs 4.7). PolyIvoks Filter's advantage is update cadence (fortnightly vs every 22 months) and iOS requirement (10.0 vs 14.0). On price, review sentiment, ratings volume and ads there is nothing between them.
