# Read A Res vs Electronic Circuit Calculator

The clearest difference is rating: Read A Res at 4.4 against Electronic Circuit Calculator's 4.0. Read A Res also leads on ratings volume (34 vs 5). Electronic Circuit Calculator's advantage is monetization model (free vs free with in-app purchases) and review sentiment (14% vs 0%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Read A Res sells 1 one-off in-app purchase and Electronic Circuit Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Read A Res holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Read A Res has 34 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 0% of Read A Res's written reviews are positive against 14% of Electronic Circuit Calculator's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
