# DigiKey vs Mouser

The clearest difference is rating: DigiKey at 4.7 against Mouser's 2.4. DigiKey also leads on review sentiment (51% vs 18%) and ratings volume (3.4K vs 34). Mouser's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

DigiKey holds the better App Store score, 4.7 against 2.4. That said, the two scores are not equally well evidenced: DigiKey has 3.4K ratings behind it against 34, so its average is the more settled of the two. Written reviews point the same way: 51% of DigiKey's written reviews are positive against 18% of Mouser's.

DigiKey ships an update every 2 months, Mouser every 6 weeks. The most recent releases landed on September 22, 2026 and September 18, 2026 respectively.
