Verdict
The clearest difference is rating: SupplyHouse at 4.9 against McMaster's 4.3. SupplyHouse also leads on review sentiment (92% vs 68%) and ratings volume (1.1K vs 220). McMaster's advantage is update cadence (every 5 weeks vs every 3 months). 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.
SupplyHouse holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: SupplyHouse has 1.1K ratings behind it against 220, 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 92% of SupplyHouse's.
McMaster ships an update every 5 weeks, SupplyHouse every 3 months. The most recent releases landed on September 17, 2026 and September 22, 2026 respectively.
