Verdict
The clearest difference is in-app purchases: Killer Butt LE at none against POTS Tracker's 1. Killer Butt LE also leads on iOS requirement (7.1 vs 15.0). POTS Tracker's advantage is update cadence (every 3 weeks vs every 6 months). On price, ads and device support there is nothing between them.
