# MyMemo vs HarborKeep

The clearest difference is monetization model: HarborKeep at free with in-app purchases against MyMemo's subscription. HarborKeep also leads on rating (5.0 vs 4.6). MyMemo's advantage is ratings volume (150 vs 1) and iOS requirement (15.0 vs 18.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. MyMemo sells 4 in-app purchases, starting at $5.90 per month and HarborKeep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

HarborKeep holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: MyMemo has 150 ratings behind it against 1, so its average is the more settled of the two.

MyMemo ships an update weekly, HarborKeep every 2 weeks. The most recent releases landed on October 15, 2026 and October 12, 2026 respectively.
