Verdict

The call

The clearest difference is in-app purchases: EMTAP at none against Unit Converter's 3. EMTAP also leads on ads (none vs shown) and rating (5.0 vs 4.8). Unit Converter's advantage is ratings volume (1.5K vs 6) and update cadence (weekly vs monthly). On price, device support and iOS requirement there is nothing between them.
