# PRO vs SJ Resistor Calculator

The clearest difference is rating: SJ Resistor Calculator at 5.0 against PRO's 1.4. PRO's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. SJ Resistor Calculator sells 5 one-off in-app purchases. PRO asks for nothing beyond the download.

SJ Resistor Calculator holds the better App Store score, 5.0 against 1.4. That said, the two scores are not equally well evidenced: PRO has 9 ratings behind it against 1, so its average is the more settled of the two.
