# ESC (Journals) vs OCTAID

The clearest difference is rating: OCTAID at 5.0 against ESC (Journals)'s 2.0. OCTAID also leads on monetization model (ad-supported vs free with in-app purchases) and ratings volume (9 vs 1). ESC (Journals)'s advantage is review sentiment (100% vs 75%) and iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

OCTAID holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: OCTAID has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of ESC (Journals)'s written reviews are positive against 75% of OCTAID's, so the app with the better star average is not the one people write more warmly about.

ESC (Journals) ships an update every 5 months, OCTAID every 2 months. The most recent releases landed on October 24, 2026 and October 14, 2026 respectively.
