Verdict
The clearest difference is ads: ID Resistors at none against Digital Electronics Guide's shown. ID Resistors also leads on ratings volume (27 vs 2) and monetization model (free vs ad-supported). On price, rating, review sentiment and update cadence 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.
On the App Store both sit at effectively the same score — 4.9 for ID Resistors against 5.0 for Digital Electronics Guide. That said, the two scores are not equally well evidenced: ID Resistors has 27 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
ID Resistors ships an update every 2 months, Digital Electronics Guide every 5 weeks. The most recent releases landed on September 19, 2026 and August 27, 2026 respectively.
