# Code Rails vs Network Puzzle

The clearest difference is in-app purchases: Code Rails at none against Network Puzzle's 1. Code Rails also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.4). Network Puzzle's advantage is update cadence (every 6 days vs every 4 weeks). On price and device support there is nothing between them.

Both are free to download. Network Puzzle sells 1 one-off in-app purchase. Code Rails asks for nothing beyond the download.

Code Rails ships an update every 4 weeks, Network Puzzle every 6 days. The most recent releases landed on October 30, 2026 and October 13, 2026 respectively.
