Verdict
The clearest difference is price: DoodleConnect at Free against Karnaugh & Boolean Minimizer's $5.99. DoodleConnect also leads on rating (4.7 vs 4.2). Karnaugh & Boolean Minimizer's advantage is review sentiment (71% vs 56%) and iOS requirement (11.0 vs 15.0). On ratings volume, update cadence, ads and in-app purchases 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
DoodleConnect is free to download; Karnaugh & Boolean Minimizer costs $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.
DoodleConnect holds the better App Store score, 4.7 against 4.2. Both are backed by a comparable volume of ratings — 22 and 56 respectively. Written reviews complicate that: 71% of Karnaugh & Boolean Minimizer's written reviews are positive against 56% of DoodleConnect's, so the app with the better star average is not the one people write more warmly about.
Karnaugh & Boolean Minimizer ships an update monthly, DoodleConnect every 2 months. The most recent releases landed on September 9, 2026 and September 21, 2026 respectively.
