# Sei vs Neuday

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.

Both are free to download. Sei sells 2 in-app purchases, starting at $5.99 per month and Neuday sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Sei holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Neuday has 14 ratings behind it against 1, so its average is the more settled of the two.

Sei ships an update fortnightly, Neuday every 3 months. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
