Verdict

The call

The clearest difference is ads: Welding Reference Pro at none against WeldKit's shown. Welding Reference Pro also leads on update cadence (every 4 days vs every 2 weeks). WeldKit's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 18.0). On price, rating, ratings volume and in-app purchases there is nothing between them.
