# Elfinbook vs ProcessOn思维导图

The clearest difference is ads: ProcessOn思维导图 at none against Elfinbook's shown. ProcessOn思维导图 also leads on review sentiment (67% vs 32%) and rating (4.8 vs 4.4). Elfinbook's advantage is ratings volume (338 vs 5) and update cadence (every 2 weeks vs every 5 weeks). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Elfinbook sells 7 in-app purchases, starting at $1.99 per month and ProcessOn思维导图 sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ProcessOn思维导图 holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Elfinbook has 338 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 32% of Elfinbook's written reviews are positive against 67% of ProcessOn思维导图's.
