Verdict

The call

The clearest difference is in-app purchases: Lennik at none against Smart Unit Conversion's 1. Lennik also leads on ads (none vs shown) and update cadence (fortnightly vs every 15 months). Smart Unit Conversion's advantage is device support (3 vs 1) and iOS requirement (13.4 vs 16.4). On price there is nothing between them.
