Verdict
The clearest difference is in-app purchases: Rest Mate at none against Developer Tools's 1. Rest Mate also leads on update cadence (weekly vs every 6 weeks). Developer Tools's advantage is device support (4 vs 1) and iOS requirement (13.0 vs 18.5). On price and ads there is nothing between them.
