# Cable Calc+ vs Stud Finder

The clearest difference is in-app purchases: Cable Calc+ at none against Stud Finder's 7. Cable Calc+ also leads on ads (none vs shown) and iOS requirement (8.0 vs 16.4). Stud Finder's advantage is rating (4.4 vs 4.0) and ratings volume (531 vs 2). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. Stud Finder sells 7 in-app purchases, starting at $3.99 per 7 days. Cable Calc+ asks for nothing beyond the download.

Stud Finder holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Stud Finder has 531 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 38% of Cable Calc+'s written reviews are positive against 36% of Stud Finder's, so the app with the better star average is not the one people write more warmly about.

Cable Calc+ ships an update every 4 months, Stud Finder every 2 months. The most recent releases landed on October 13, 2026 and October 24, 2026 respectively.
