# Frame vs EnginPrep

The clearest difference is in-app purchases: Frame at none against EnginPrep's 1. Frame also leads on iOS requirement (10.0 vs 16.4). EnginPrep's advantage is update cadence (every 3 weeks vs every 6 months). On price, ads and device support there is nothing between them.

Both are free to download. EnginPrep sells 1 one-off in-app purchase. Frame asks for nothing beyond the download.

Frame ships an update every 6 months, EnginPrep every 3 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
