Both are free to download. LogicGate sells 2 in-app purchases, starting at $4.99 per 7 days. Digital Circuit Simulator Lite asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

LogicGate holds the better App Store score, 3.0 against 2.8. That said, the two scores are not equally well evidenced: Digital Circuit Simulator Lite has 29 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 33% of Digital Circuit Simulator Lite's written reviews are positive against 0% of LogicGate's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 30, 2026 and September 24, 2026 respectively.
