# Number Therapy vs F

The clearest difference is price: Number Therapy at $29.99 against F's $149.99. Number Therapy also leads on rating (4.7 vs 4.4) and ratings volume (268 vs 8). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.

Number Therapy costs $29.99 and F $149.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Number Therapy holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Number Therapy has 268 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 83% of Number Therapy's written reviews are positive against 86% of F's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on November 5, 2026 and November 1, 2026 respectively.
