Verdict
The clearest difference is ads: Pillow at none against Sleep Tracker's shown. Pillow also leads on ratings volume (96K vs 8K) and chart position (#155 vs unranked). Sleep Tracker's advantage is rating (4.7 vs 4.4) and iOS requirement (15.0 vs 17.0). On price, review sentiment, 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. Pillow sells 5 in-app purchases, starting at $19.99 per month and Sleep Tracker sells 16 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Sleep Tracker holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Pillow has 96K ratings behind it against 8K, 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 49% of Sleep Tracker's.
Pillow ships an update every 9 days, Sleep Tracker every 3 weeks. Both last shipped on October 31, 2026.
