# StrengthMark vs Five/Three/One

The clearest difference is in-app purchases: StrengthMark at none against Five/Three/One's 6. StrengthMark also leads on review sentiment (92% vs 78%). Five/Three/One's advantage is update cadence (every 2 weeks vs every 3 months) and ratings volume (1.2K vs 15). On price, rating, ads and device support there is nothing between them.

Both are free to download. Five/Three/One sells 6 one-off in-app purchases. StrengthMark asks for nothing beyond the download.

Five/Three/One holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Five/Three/One has 1.2K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 92% of StrengthMark's written reviews are positive against 78% of Five/Three/One's, so the app with the better star average is not the one people write more warmly about.

StrengthMark ships an update every 3 months, Five/Three/One every 2 weeks. The most recent releases landed on September 28, 2026 and October 11, 2026 respectively.
