Verdict
The clearest difference is price: i at Free against Punch Board Calculator's $0.99. i also leads on update cadence (monthly vs every 10 months) and ratings volume (441 vs 18). Punch Board Calculator's advantage is rating (3.8 vs 2.1) and review sentiment (42% vs 10%). On ads, in-app purchases and device support there is nothing between them.
