# Vexed+ vs SmartGo One

The clearest difference is price: SmartGo One at Free against Vexed+'s $0.99. SmartGo One also leads on rating (4.8 vs 4.4) and ratings volume (2K vs 5). Vexed+'s advantage is in-app purchases (none vs 47) and review sentiment (100% vs 77%). On ads and device support there is nothing between them.

SmartGo One is free to download; Vexed+ costs $0.99 up front. SmartGo One sells 47 in-app purchases, starting at $4.99 per month. Vexed+ asks for nothing beyond the download.

SmartGo One holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: SmartGo One has 2K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Vexed+'s written reviews are positive against 77% of SmartGo One's, so the app with the better star average is not the one people write more warmly about.

Vexed+ ships an update every 3 days, SmartGo One every 10 days. The most recent releases landed on October 14, 2026 and October 19, 2026 respectively.
