Verdict
The clearest difference is monetization model: Relay Network at free against OSDP Reader's paid. Relay Network also leads on iOS requirement (9.0 vs 15). OSDP Reader's advantage is update cadence (every 2 months vs every 6 months). On price, ads, in-app purchases and device support there is nothing between them.
