Verdict
The clearest difference is in-app purchases: BlueID Keys at none against Smart Printer's 7. BlueID Keys also leads on ads (none vs shown) and iOS requirement (13.0 vs 17). Smart Printer's advantage is update cadence (every 3 days vs every 10 months). On price and device support there is nothing between them.
