Verdict
The clearest difference is in-app purchases: Batting Reaction Time at none against Seam Reader's 4. Batting Reaction Time also leads on ads (none vs shown) and review sentiment (50% vs 42%). Seam Reader's advantage is update cadence (every 8 days vs every 11 months) and rating (3.9 vs 3.5). On price and device support there is nothing between them.

Both are free to download. Seam Reader sells 4 one-off in-app purchases. Batting Reaction Time asks for nothing beyond the download.
Seam Reader holds the better App Store score, 3.9 against 3.5. That said, the two scores are not equally well evidenced: Seam Reader has 64 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of Batting Reaction Time's written reviews are positive against 42% of Seam Reader's, so the app with the better star average is not the one people write more warmly about.
Batting Reaction Time ships an update every 11 months, Seam Reader every 8 days. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
