Verdict
The clearest difference is review sentiment: Electronics Engineer Helper at 98% against Code Viewer's 49%. Electronics Engineer Helper also leads on rating (4.8 vs 3.4) and ratings volume (436 vs 18). Code Viewer's advantage is iOS requirement (7.0 vs 17.0). On price, 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
Both are free to download. Code Viewer sells 1 one-off in-app purchase and Electronics Engineer Helper sells 2 in-app purchases, starting at $4.89 per year. Whichever you choose, the download price is not the number that matters.
Electronics Engineer Helper holds the better App Store score, 4.8 against 3.4. That said, the two scores are not equally well evidenced: Electronics Engineer Helper has 436 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 49% of Code Viewer's written reviews are positive against 98% of Electronics Engineer Helper's.
Code Viewer ships an update every 3 weeks, Electronics Engineer Helper monthly. Both last shipped on October 7, 2026.
