Verdict

The call

The clearest difference is rating: Folio at 4.7 against MobileKey's 1.0. Folio also leads on review sentiment (64% vs 32%) and update cadence (every 8 days vs every 3 months). MobileKey's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement there is nothing between them.
