# Physics Formulas Lite vs Chemify

The clearest difference is in-app purchases: Physics Formulas Lite at none against Chemify's 7. Physics Formulas Lite also leads on ads (none vs shown) and ratings volume (60 vs 4). Chemify's advantage is rating (5.0 vs 4.6) and update cadence (every 3 weeks vs every 4 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Chemify sells 6 in-app purchases, starting at $7.99 per month. Physics Formulas Lite asks for nothing beyond the download.

Chemify holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Physics Formulas Lite has 60 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 81% of Physics Formulas Lite's written reviews are positive against 100% of Chemify's.

Physics Formulas Lite ships an update every 4 months, Chemify every 3 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
