The Rapsodo MLM2Pro does not require a subscription to use its basic features as a launch monitor. However, it does include a one-year free Premium Membership with the purchase, which unlocks advanced features like access to 30,000+ simulation courses, spin rate and spin axis data (with Callaway RPT balls), dual-camera swing replay, and cloud storage for up to 10,000 shots. After the first year, continuing access to these premium features requires a subscription, which costs $199 annually.
