# OOS vs 爱情计算器

The clearest difference is in-app purchases: OOS at none against 爱情计算器's 1. OOS also leads on iOS requirement (11.0 vs 16.6). 爱情计算器's advantage is update cadence (every 6 days vs fortnightly). On price, ads and device support there is nothing between them.

Both are free to download. 爱情计算器 sells 1 one-off in-app purchase. OOS asks for nothing beyond the download.

OOS ships an update fortnightly, 爱情计算器 every 6 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
