Stud Finder゜ is free to download; AltFuelUS costs $0.99 up front. Stud Finder゜ sells 1 one-off in-app purchase. AltFuelUS asks for nothing beyond the download.
Stud Finder゜ holds the better App Store score, 4.5 against 4.0.

Written reviews complicate that: 100% of AltFuelUS's written reviews are positive against 35% of Stud Finder゜'s, so the app with the better star average is not the one people write more warmly about.
AltFuelUS ships an update every 13 months, Stud Finder゜ every 4 months. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
