Verdict
The clearest difference is update cadence: HamWatch at every 10 days against Propagation Tools's every 9 months. HamWatch also leads on chart position (#199 vs unranked). Propagation Tools's advantage is price ($0.29 vs $4.99). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
