Verdict

The call

The clearest difference is price: Fish Identifier at Free against Knot Guide's $2.99. Fish Identifier also leads on iOS requirement (14.0 vs 17.0). Knot Guide's advantage is rating (4.6 vs 3.6) and ads (none vs shown). On update cadence, in-app purchases, monetization model and device support there is nothing between them.
