Prove It at a Glance
Prove It offers barcode scanning with evidence-based supplement evaluations, learning modules, and an expert chat feature. The app positions itself around scientific rigor. However, it requires a subscription of $29.99 to $99.99 per year with no free scanning tier — users must complete extensive onboarding before discovering the paywall.
With over 13,000 App Store reviews, user feedback paints a mixed picture. While the interface is praised for being clean, recurring complaints center on database gaps, accuracy concerns, aggressive monetization, and camera technical issues.
Known Issues with Prove It
Aggressive Paywall
Users report extensive onboarding (questions, setup) that ultimately leads to a paywall. No free scanning is available, meaning you cannot evaluate the app's quality before paying $29.99–$99.99/year.
Database Gaps
Multiple reviewers report many supplements missing from the database, with manual photo upload functionality that frequently fails. This limits the app's usefulness for users with diverse supplement collections.
Accuracy Concerns
A supplement store employee reported the app provided inaccurate ratings, including false allergen claims. Other users have questioned the reliability of scoring methodology.
Technical Problems
Users report white camera screens, scanning errors, and broken functionality when adding favorites to stacks. The scanning process requires toggling between photo and barcode modes.
