# Code vs ZKIOT

The clearest difference is ads: Code at none against ZKIOT's shown. ZKIOT's advantage is update cadence (fortnightly vs every 8 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Code ships an update every 8 months, ZKIOT fortnightly. The most recent releases landed on October 11, 2026 and September 27, 2026 respectively.
