The clearest difference is in-app purchases: Delta Services at none against Shell Identifier's 2. Delta Services also leads on ads (none vs shown) and iOS requirement (12.4 vs 15.0). Shell Identifier's advantage is update cadence (every 3 weeks vs every 5 weeks). On price and device support there is nothing between them.
