# Eng Dynamics vs Engineering Physics Quiz

The clearest difference is in-app purchases: Eng Dynamics at none against Engineering Physics Quiz's 7. Eng Dynamics also leads on ads (none vs shown) and iOS requirement (9.0 vs 12.0). Engineering Physics Quiz's advantage is update cadence (every 3 weeks vs every 8 months). On price and device support there is nothing between them.

Both are free to download. Engineering Physics Quiz sells 7 in-app purchases, starting at $4.99 per month. Eng Dynamics asks for nothing beyond the download.

Eng Dynamics ships an update every 8 months, Engineering Physics Quiz every 3 weeks. The most recent releases landed on June 10, 2026 and March 3, 2026 respectively.
