Verdict
The clearest difference is in-app purchases: BlueIODevin at none against Locky's 6. BlueIODevin also leads on ads (none vs shown). Locky's advantage is update cadence (every 2 months vs every 28 months) and iOS requirement (14.0 vs 16.2). On price and device support there is nothing between them.
