# TopGuru vs V

The clearest difference is rating: V at 4.0 against TopGuru's 3.5. V also leads on update cadence (weekly vs every 3 weeks). TopGuru's advantage is review sentiment (29% vs 0%) and ratings volume (412 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. TopGuru sells 21 in-app purchases, starting at $9.99 per month and V sells 1 in-app purchase, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

V holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: TopGuru has 412 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 29% of TopGuru's written reviews are positive against 0% of V's, so the app with the better star average is not the one people write more warmly about.

TopGuru ships an update every 3 weeks, V weekly. The most recent releases landed on October 27, 2026 and October 13, 2026 respectively.
