FAQ

What's the best free welding app?

DimeVision (3 free scans/month), Fronius WeldConnect, and Miller Calculator are the best free options. Each serves different purposes.

Can welding apps replace a real welding instructor?

No app replaces hands-on instruction, but apps like DimeVision and SkillCat can supplement learning when an instructor isn't available.

Are welding apps worth paying for?

If you're serious about welding: yes. DimeVision Premium ($9.99/mo) pays for itself if it prevents one bad weld. Welding Pro ($12.99) is worth it for professionals bidding projects.

Do I need multiple welding apps?

Probably. Most welders use 2-3 apps: one for analysis (DimeVision), one for calculations (Welding Pro/Fronius), and one for learning (SkillCat).

Which app is best for beginners?

Start with DimeVision (free tier) to get AI feedback on your welds, and SkillCat to learn fundamentals. Add Miller Calculator for quick reference.
