Verdict
The clearest difference is rating: Electronic Circuit Calculator at 4.0 against KiCad Viewer's 2.1. KiCad Viewer's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.0). On price, review sentiment, ratings volume 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
Both are free to download. Electronic Circuit Calculator sells 1 one-off in-app purchase and KiCad Viewer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Electronic Circuit Calculator holds the better App Store score, 4.0 against 2.1. Both are backed by a comparable volume of ratings — 5 and 7 respectively. Written reviews point the same way: 14% of Electronic Circuit Calculator's written reviews are positive against 13% of KiCad Viewer's.
