# DevPrep vs Q

The clearest difference is in-app purchases: Q at none against DevPrep's 1. Q also leads on ads (none vs shown) and iOS requirement (12.0 vs 17.0). DevPrep's advantage is update cadence (every 2 days vs every 8 months). On price and device support there is nothing between them.

Both are free to download. DevPrep sells 1 in-app purchase, starting at $2.99 per 6 months. Q asks for nothing beyond the download.

DevPrep ships an update every 2 days, Q every 8 months. The most recent releases landed on October 22, 2026 and October 7, 2026 respectively.
