Verdict
The clearest difference is price: Information Sharing Guide at Free against Purdue Tomato Doctor's $0.99. Purdue Tomato Doctor's advantage is update cadence (every 4 months vs every 86 months) and iOS requirement (8.4 vs 10.0). On ads, in-app purchases and device support there is nothing between them.
