# FP Notebook vs X

The clearest difference is in-app purchases: X at none against FP Notebook's 3. X also leads on update cadence (every 8 days vs every 2 months). FP Notebook's advantage is ratings volume (3.3K vs 1) and chart position (#54 vs unranked). On price, rating, ads and device support there is nothing between them.

Both are free to download. FP Notebook sells 3 in-app purchases, starting at $1.99 per month. X asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for FP Notebook against 5.0 for X. That said, the two scores are not equally well evidenced: FP Notebook has 3.3K ratings behind it against 1, so its average is the more settled of the two.

FP Notebook ships an update every 2 months, X every 8 days. The most recent releases landed on October 13, 2026 and October 7, 2026 respectively.
