Verdict
The clearest difference is ads: Circuitry at none against Digital Electronics Guide's shown. Circuitry also leads on ratings volume (291 vs 2). Digital Electronics Guide's advantage is update cadence (every 5 weeks vs every 46 months) and monetization model (ad-supported vs paid). On price, review sentiment, in-app purchases and device support 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.
Digital Electronics Guide holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Circuitry has 291 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 96% of Circuitry's written reviews are positive against 100% of Digital Electronics Guide's.
Circuitry ships an update every 46 months, Digital Electronics Guide every 5 weeks. The most recent releases landed on October 6, 2026 and October 1, 2026 respectively.
