Verdict
The clearest difference is rating: Hornady Reloading Guide at 4.6 against iWarmU's 2.1. Hornady Reloading Guide also leads on ratings volume (17K vs 73) and update cadence (every 2 months vs every 6 months). iWarmU's advantage is in-app purchases (none vs 3) and iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.
