Verdict

The call

The clearest difference is price: Trackkarma at Free against PenaltyTimer's $1.99. Trackkarma also leads on update cadence (every 2 weeks vs every 8 months) and rating (5.0 vs 4.8). PenaltyTimer's advantage is ratings volume (13 vs 1) and chart position (#19 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
