# ChemZero vs Ingredients Scanner

The clearest difference is rating: Ingredients Scanner at 5.0 against ChemZero's 4.4. Ingredients Scanner also leads on review sentiment (100% vs 61%) and monetization model (free with in-app purchases vs subscription). ChemZero's advantage is ads (none vs shown) and ratings volume (93 vs 9). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. ChemZero sells 7 in-app purchases, starting at $7.99 per 7 days and Ingredients Scanner sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Ingredients Scanner holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: ChemZero has 93 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 61% of ChemZero's written reviews are positive against 100% of Ingredients Scanner's.

Both ship on a similar rhythm, roughly every 9 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
