# HEV vs CTA Go

The clearest difference is in-app purchases: CTA Go at none against HEV's 3. CTA Go also leads on device support (3 vs 1) and iOS requirement (13.0 vs 15.0). HEV's advantage is update cadence (every 5 weeks vs every 15 months). On price and ads there is nothing between them.

Both are free to download. HEV sells 3 one-off in-app purchases. CTA Go asks for nothing beyond the download.

HEV ships an update every 5 weeks, CTA Go every 15 months. The most recent releases landed on October 26, 2026 and October 27, 2026 respectively.
