The clearest difference is in-app purchases: VcfLookup at none against Pomodoro Study's 9. VcfLookup also leads on update cadence (every 3 weeks vs every 3 months) and rating (5.0 vs 4.8). Pomodoro Study's advantage is ratings volume (6 vs 1). On price, ads and device support there is nothing between them.

VcfLookup holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Pomodoro Study has 6 ratings behind it against 1, so its average is the more settled of the two.
