Verdict

The call

The clearest difference is in-app purchases: U at none against V720's 13. U also leads on ads (none vs shown). V720's advantage is rating (4.3 vs 4.0) and ratings volume (4.8K vs 536). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. V720 sells 13 in-app purchases, starting at $0.39 per month. U asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

V720 holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: V720 has 4.8K ratings behind it against 536, so its average is the more settled of the two. Written reviews complicate that: 9% of V720's written reviews are positive against 15% of U's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

V720 ships an update every 3 weeks, U fortnightly. Both last shipped on October 14, 2026.
