Verdict
The clearest difference is in-app purchases: TrainLog at none against 1RM Percentage Calculator's 1. TrainLog also leads on update cadence (every 5 days vs every 30 months) and iOS requirement (13.0 vs 15.1). 1RM Percentage Calculator's advantage is ads (none vs shown). On price and device support there is nothing between them.
