Verdict
The clearest difference is in-app purchases: CalBio at none against Pomodoro Study's 9. CalBio also leads on rating (5.0 vs 4.8). Pomodoro Study's advantage is update cadence (every 3 months vs every 10 months) and ratings volume (6 vs 2). On price, ads, device support and iOS requirement there is nothing between them.
