Verdict
The clearest difference is review sentiment: Circuitry at 51% against Chemical Engineering+'s 0%. Circuitry also leads on rating (3.9 vs 3.0) and in-app purchases (none vs 6). Chemical Engineering+'s advantage is update cadence (every 2 months vs every 4 months). On price, ads 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. Chemical Engineering+ sells 6 in-app purchases, starting at $9.99 per month. Circuitry asks for nothing beyond the download.
Circuitry holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Circuitry has 156 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 51% of Circuitry's written reviews are positive against 0% of Chemical Engineering+'s.
Circuitry ships an update every 4 months, Chemical Engineering+ every 2 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
