Verdict

The call

The clearest difference is review sentiment: Blood Test Grapher at 76% against Tempur® Sleeptracker's 37%. Blood Test Grapher also leads on update cadence (every 5 weeks vs every 3 months) and iOS requirement (9.3 vs 17.5). Tempur® Sleeptracker's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Tempur® Sleeptracker holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Tempur® Sleeptracker has 35K ratings behind it against 29, so its average is the more settled of the two. Written reviews complicate that: 76% of Blood Test Grapher's written reviews are positive against 37% of Tempur® Sleeptracker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Blood Test Grapher ships an update every 5 weeks, Tempur® Sleeptracker every 3 months. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
