Finally...the first objective way to see if your mattress really supports your spine properly. With this patent pending new technology, you can instantly check the support of your mattress in just seconds! With the Mattress Checker app you can use your iphone, or iPad device to take a picture of someone on the mattress (you could use the timer feature if you are alone or even use a mirror for a Selfie), then place 5 dots along the path of the spine from the bottom of the spine to the top and then let the app. calculate your posture spinal alignment on the mattress. You can also compare one mattress to another to see if a mattress has no support or whether the Back Science mattress really does align your spine and give you that perfect sleeping posture or in the case of an adjustable mattress like the Air-Pedic, change the zone pressure to find the best spinal support settings.

Verdict

The call

The clearest difference is ratings volume: UPRIGHT at 3.9K against Mattress Checker's 4. UPRIGHT also leads on rating (4.6 vs 4.3). Mattress Checker's advantage is review sentiment (50% vs 25%) and iOS requirement (13.0 vs 15.1). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

UPRIGHT holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: UPRIGHT has 3.9K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of Mattress Checker's written reviews are positive against 25% of UPRIGHT's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Mattress Checker ships an update every 2 months, UPRIGHT every 5 weeks. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
