Verdict

The call

The clearest difference is ads: Unit Converter at none against Moolight's shown. Unit Converter also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 15.0). On price, update cadence, in-app purchases and device support there is nothing between them.
