# FP Notebook vs MobilEM

The clearest difference is rating: FP Notebook at 4.8 against MobilEM's 3.6. FP Notebook also leads on ratings volume (3.3K vs 39) and review sentiment (58% vs 45%). MobilEM's advantage is monetization model (free with in-app purchases vs subscription). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. FP Notebook sells 3 in-app purchases, starting at $1.99 per month and MobilEM sells 12 in-app purchases, starting at $1.99 per year. Whichever you choose, the download price is not the number that matters.

FP Notebook holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: FP Notebook has 3.3K ratings behind it against 39, so its average is the more settled of the two. Written reviews point the same way: 58% of FP Notebook's written reviews are positive against 45% of MobilEM's.

Both ship on a similar rhythm, roughly every 2 months. Both last shipped on September 29, 2026.
