The recent update transitioned the app from a one-time purchase model to a recurring subscription, triggering a severe decline in user satisfaction. The average Android rating dropped by 1.02 stars, falling from 4.55 to 3.53 post-release. This shift to a recurring weekly or yearly fee, alongside paywalling previously accessible anatomy reference materials, has resulted in a strongly negative net impact.

The recent bug fix update resulted in a negative impact, with the iOS rating average declining by 0.92 stars to 4.08 stars. While users continue to praise the high-quality 3D anatomical visualizations, this positive reception is offset by frequent rating prompts and monetization friction. Reviewers describe being locked out of previously purchased content and allege unexpected charges upon starting a free trial.
