Verdict

The call

The clearest difference is rating: ViGuide at 4.5 against Installer App's 3.0. ViGuide also leads on ratings volume (199 vs 7). Installer App's advantage is review sentiment (50% vs 41%). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

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 7, so its average is the more settled of the two. Written reviews complicate that: 50% of Installer App's written reviews are positive against 41% of ViGuide's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on September 1, 2026 and September 27, 2026 respectively.
