Verdict

The call

The clearest difference is in-app purchases: Numsy at none against AllBaseConvert's 1. Numsy also leads on ads (none vs shown). AllBaseConvert's advantage is update cadence (every 8 months vs every 21 months) and iOS requirement (13.0 vs 16.6). On price and device support there is nothing between them.
