Verdict

The call

The clearest difference is in-app purchases: Butterfly Challenge at none against HockeyTracker's 2. Butterfly Challenge also leads on iOS requirement (13.0 vs 17.0). HockeyTracker's advantage is update cadence (fortnightly vs every 63 months) and ratings volume (1K vs 51). On price, rating, review sentiment and ads there is nothing between them.
