Verdict
The clearest difference is rating: McMaster at 4.3 against Lincoln Electric's 3.4. McMaster also leads on update cadence (every 5 weeks vs every 14 months) and ratings volume (220 vs 5). Lincoln Electric's advantage is iOS requirement (7.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
McMaster holds the better App Store score, 4.3 against 3.4. That said, the two scores are not equally well evidenced: McMaster has 220 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 68% of McMaster's written reviews are positive against 50% of Lincoln Electric's.
McMaster ships an update every 5 weeks, Lincoln Electric every 14 months. The most recent releases landed on October 24, 2026 and October 6, 2026 respectively.
