# iCircuit vs Digital Electronics Guide

The clearest difference is price: Digital Electronics Guide at Free against iCircuit's $12.99. Digital Electronics Guide also leads on rating (5.0 vs 3.8) and review sentiment (100% vs 61%). iCircuit's advantage is ads (none vs shown) and ratings volume (135 vs 2). On update cadence and device support there is nothing between them.

Digital Electronics Guide is free to download; iCircuit costs $12.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month. Digital Electronics Guide asks for nothing beyond the download.

Digital Electronics Guide holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: iCircuit has 135 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 61% of iCircuit's written reviews are positive against 100% of Digital Electronics Guide's.

iCircuit ships an update every 4 weeks, Digital Electronics Guide every 5 weeks. The most recent releases landed on October 19, 2026 and October 1, 2026 respectively.
