# AR vs ZeroOneFlow

The clearest difference is in-app purchases: AR at none against ZeroOneFlow's 1. AR also leads on iOS requirement (11.3 vs 16.2). ZeroOneFlow's advantage is update cadence (every 3 weeks vs every 4 months). On price, ads and device support there is nothing between them.

Both are free to download. ZeroOneFlow sells 1 one-off in-app purchase. AR asks for nothing beyond the download.

AR ships an update every 4 months, ZeroOneFlow every 3 weeks. The most recent releases landed on September 30, 2026 and October 7, 2026 respectively.
