Verdict

The call

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.
