Visual Vertical makes high-grade subjective visual vertical (SVV) testing accessible to every practitioner — no expensive equipment required. SVV testing is a sensitive, validated measure for brainstem lesions and otolithic dysfunction, widely used in neurology and vestibular rehabilitation. Until now, accurate testing required bulky, costly apparatus. Visual Vertical changes that: all you need is your iPhone, a bucket, and a small piece of Blu Tack. How it works Mount your iPhone inside the bottom of a bucket using Blu Tack. The patient holds the bucket to their face and adjusts a line on screen until it appears vertical to them. The app records the deviation and calculates your result — accurate readings in minutes, at a fraction of the traditional cost. What you can measure - Left eye, right eye, or both eyes open - Single readings or full sequences across all conditions - One or three readings per condition, with automatic averaging Clean, minimal results screens make it easy to record and communicate findings.

Verdict

The call

The clearest difference is review sentiment: Visual Vertical at 100% against Scoliosis Tools's 36%. Visual Vertical also leads on ratings volume (5 vs 1). Scoliosis Tools's advantage is rating (5.0 vs 2.0) and price ($4.99 vs $11.99). On ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Scoliosis Tools holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: Visual Vertical has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Visual Vertical's written reviews are positive against 36% of Scoliosis Tools's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Visual Vertical ships an update every 38 months, Scoliosis Tools every 2 months. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
