The clearest difference is in-app purchases: S+K at none against Video tachometer's 1. S+K also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 84%). Video tachometer's advantage is ratings volume (84 vs 2). On price, ads and device support there is nothing between them.

Both are free to download. Video tachometer sells 1 one-off in-app purchase. S+K asks for nothing beyond the download.

S+K holds the better App Store score, 5.0 against 4.6.
