# PolyGPT vs The Visual Key

The clearest difference is update cadence: The Visual Key at every 3 days against PolyGPT's fortnightly. PolyGPT's advantage is iOS requirement (12.0 vs 14.0). On price, ads, in-app purchases and device support there is nothing between them.

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

PolyGPT ships an update fortnightly, The Visual Key every 3 days. The most recent releases landed on June 2, 2026 and September 9, 2026 respectively.
