Verdict
The clearest difference is ads: Pillow at none against NightWell's shown. Pillow also leads on ratings volume (96K vs 16) and chart position (#156 vs unranked). NightWell's advantage is review sentiment (60% vs 42%). On price, rating, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. NightWell sells 9 in-app purchases, starting at $9.99 per month and Pillow sells 5 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
NightWell holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Pillow has 96K ratings behind it against 16, so its average is the more settled of the two. Written reviews point the same way: 60% of NightWell's written reviews are positive against 42% of Pillow's.
NightWell ships an update every 3 weeks, Pillow every 9 days. The most recent releases landed on November 6, 2026 and November 8, 2026 respectively.
