Verdict

The call

The clearest difference is update cadence: Sei at fortnightly against Neuday's every 3 months. Sei also leads on rating (5.0 vs 4.6). Neuday's advantage is monetization model (free vs freemium) and ratings volume (14 vs 1). On price, ads, in-app purchases and device support there is nothing between them.
