Verdict

The call

The clearest difference is monetization model: RemNote at free against AlgoApp's free with in-app purchases. RemNote also leads on review sentiment (74% vs 50%). AlgoApp's advantage is ratings volume (20K vs 1.7K) and device support (4 vs 2). On price, rating, update cadence and ads there is nothing between them.
