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.

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.
