# iORA vs Visual Periodic Table Chemie

The clearest difference is price: iORA at Free against Visual Periodic Table Chemie's $1.99. iORA also leads on rating (5.0 vs 4.5) and ratings volume (12 vs 2). Visual Periodic Table Chemie's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (11.0 vs 14.3). On review sentiment, ads, in-app purchases and device support there is nothing between them.

iORA is free to download; Visual Periodic Table Chemie costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

iORA holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: iORA has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

iORA ships an update every 2 months, Visual Periodic Table Chemie every 3 weeks. The most recent releases landed on October 9, 2026 and October 27, 2026 respectively.
