# Zettelbox vs MyMemo

The clearest difference is monetization model: Zettelbox at freemium against MyMemo's subscription. MyMemo's advantage is review sentiment (67% vs 31%) and rating (4.6 vs 4.3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Zettelbox sells 3 in-app purchases, starting at $4.99 per month and MyMemo sells 4 in-app purchases, starting at $5.90 per month. Whichever you choose, the download price is not the number that matters.

MyMemo holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: MyMemo has 150 ratings behind it against 24, so its average is the more settled of the two. Written reviews point the same way: 31% of Zettelbox's written reviews are positive against 67% of MyMemo's.

Zettelbox ships an update every 2 weeks, MyMemo weekly. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
