# Pillow vs Rem

The clearest difference is update cadence: Pillow at every 9 days against Rem's every 6 weeks. Pillow also leads on ratings volume (96K vs 2.7K) and rating (4.4 vs 4.2). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Pillow sells 5 in-app purchases, starting at $19.99 per month and Rem sells 8 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Pillow holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Pillow has 96K ratings behind it against 2.7K, so its average is the more settled of the two. Written reviews point the same way: 42% of Pillow's written reviews are positive against 38% of Rem's.

Pillow ships an update every 9 days, Rem every 6 weeks. The most recent releases landed on November 11, 2026 and November 7, 2026 respectively.
