Verdict
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.
