# Instructions vs DOCFIX

The clearest difference is ads: DOCFIX at none against Instructions's shown. DOCFIX also leads on iOS requirement (13 vs 15.0). Instructions's advantage is update cadence (every 2 weeks vs every 2 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Instructions sells 1 one-off in-app purchase and DOCFIX sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Instructions ships an update every 2 weeks, DOCFIX every 2 months. The most recent releases landed on September 9, 2026 and August 27, 2026 respectively.
