# EZI vs KeyPay

The clearest difference is in-app purchases: EZI at none against KeyPay's 10. KeyPay's advantage is update cadence (every 2 months vs every 10 months) and iOS requirement (13 vs 15.5). On price, ads and device support there is nothing between them.

Both are free to download. KeyPay sells 10 one-off in-app purchases. EZI asks for nothing beyond the download.
