Verdict

The call

The clearest difference is review sentiment: Memo at 100% against Peak's 64%. Memo also leads on ads (none vs shown) and rating (5.0 vs 4.7). Peak's advantage is ratings volume (146K vs 3) and device support (4 vs 1). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Peak sells 10 in-app purchases, starting at $2.99 per month and Memo sells 10 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Memo holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Peak has 146K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 64% of Peak's written reviews are positive against 100% of Memo's.

UpkeepUpdate frequency

Peak ships an update fortnightly, Memo every 3 days. The most recent releases landed on November 8, 2026 and November 7, 2026 respectively.
