# Vector vs Only One

The clearest difference is review sentiment: Only One at 100% against Vector's 40%. Only One also leads on rating (5.0 vs 4.2). Vector's advantage is update cadence (every 6 weeks vs every 39 months) and ratings volume (10 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Vector costs $0.99 and Only One $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Only One holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Vector has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 40% of Vector's written reviews are positive against 100% of Only One's.

Vector ships an update every 6 weeks, Only One every 39 months. The most recent releases landed on October 13, 2026 and October 1, 2026 respectively.
