Verdict
The clearest difference is rating: Alto at 4.7 against Poseidon Ferry's 4.0. Alto also leads on ratings volume (4.4K vs 4). Poseidon Ferry's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs every 3 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.
