# Command vs RLM

The clearest difference is in-app purchases: Command at none against RLM's 1. Command also leads on update cadence (every 5 days vs every 4 weeks) and ratings volume (5 vs 1). On price, rating, ads and monetization model there is nothing between them.

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

On the App Store both sit at effectively the same score — 5.0 for Command against 5.0 for RLM. That said, the two scores are not equally well evidenced: Command has 5 ratings behind it against 1, so its average is the more settled of the two.

Command ships an update every 5 days, RLM every 4 weeks. The most recent releases landed on September 9, 2026 and September 10, 2026 respectively.
