# ApiClient vs ROS

The clearest difference is in-app purchases: ROS at none against ApiClient's 1. ROS also leads on ads (none vs shown) and update cadence (every 2 days vs every 3 months). ApiClient's advantage is iOS requirement (16.0 vs 26.1). On price and device support there is nothing between them.

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

ApiClient ships an update every 3 months, ROS every 2 days. The most recent releases landed on October 11, 2026 and September 29, 2026 respectively.
