Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ViGuide holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: ViGuide has 199 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 41% of ViGuide's written reviews are positive against 50% of Wrench's, so the app with the better star average is not the one people write more warmly about.
ViGuide ships an update every 5 weeks, Wrench monthly. The most recent releases landed on October 18, 2026 and October 8, 2026 respectively.
