# ApiClient vs ROS2 Visualizer

The clearest difference is in-app purchases: ROS2 Visualizer at none against ApiClient's 1. ROS2 Visualizer also leads on ads (none vs shown). ApiClient's advantage is update cadence (every 3 months vs every 7 months) and iOS requirement (16.0 vs 18.5). On price and device support there is nothing between them.

Both are free to download. ApiClient sells 1 one-off in-app purchase. ROS2 Visualizer asks for nothing beyond the download.

ApiClient ships an update every 3 months, ROS2 Visualizer every 7 months. The most recent releases landed on October 11, 2026 and October 10, 2026 respectively.
