Verdict
The clearest difference is in-app purchases: BAP String Building Guide at none against WeldKit's 1. BAP String Building Guide also leads on ads (none vs shown). WeldKit's advantage is update cadence (every 2 weeks vs every 2 months) and iOS requirement (15.1 vs 18.5). On price and device support there is nothing between them.
