# Supplement Scanner vs ZendBack

The clearest difference is in-app purchases: ZendBack at none against Supplement Scanner's 10. ZendBack also leads on rating (5.0 vs 4.6) and iOS requirement (16.0 vs 18.0). Supplement Scanner's advantage is ratings volume (266 vs 2) and update cadence (every 9 days vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. Supplement Scanner sells 10 in-app purchases, starting at $6.99 per 7 days. ZendBack asks for nothing beyond the download.

ZendBack holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Supplement Scanner has 266 ratings behind it against 2, so its average is the more settled of the two.

Supplement Scanner ships an update every 9 days, ZendBack every 2 months. The most recent releases landed on November 12, 2026 and November 5, 2026 respectively.
