Verdict

The call

The clearest difference is rating: RemNote at 4.8 against Red Sheet's 4.2. RemNote also leads on ads (none vs shown) and ratings volume (1.7K vs 5). Red Sheet's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 16.5). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. RemNote sells 8 in-app purchases, starting at $14.99 per month and Red Sheet sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

RemNote holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: RemNote has 1.7K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 73% of RemNote's written reviews are positive against 78% of Red Sheet's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 days. The most recent releases landed on October 21, 2026 and October 20, 2026 respectively.
