Verdict
The clearest difference is in-app purchases: IPF GL at none against 1RM Calculator's 3. IPF GL also leads on update cadence (every 3 weeks vs every 4 months). 1RM Calculator's advantage is ratings volume (116 vs 2) and iOS requirement (15.0 vs 18.6). On price, rating, ads and device support there is nothing between them.
