Verdict
The clearest difference is update cadence: W.W. Grainger, Inc. at fortnightly against One MPM's every 3 months. W.W. Grainger, Inc. also leads on ratings volume (27K vs 6). One MPM's advantage is monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.8). On price, ads, in-app purchases and device support there is nothing between them.
