Verdict

The call

The clearest difference is in-app purchases: Serializd at none against Letterboxd's 16. Serializd also leads on iOS requirement (15.1 vs 17.5). Letterboxd's advantage is ratings volume (88K vs 1.2K) and rating (4.8 vs 4.5). On price, review sentiment, update cadence and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Letterboxd holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Letterboxd has 88K ratings behind it against 1.2K, so its average is the more settled of the two. Written reviews complicate that: 59% of Letterboxd's written reviews are positive against 62% of Serializd's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Letterboxd ships an update fortnightly, Serializd every 3 weeks. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
