Milestone for Mac

Master online courses, guitar, and piano lessons with seamless marking and looping.

Features

• Ad-Free YouTube Player — Stream your learning material completely uninterrupted. No accounts or logins required.
• Instant Video Markers — Drop custom timestamps right onto the video timeline so you can jump directly back to specific parts or sections.
• Seamless A-B Looping — Select any two markers to loop that exact section indefinitely (incredibly helpful for practicing a tough guitar riff, a piano measure, or reviewing a complex piece of code).
• Privacy-First — Everything—your markers, history, and configuration—is saved completely locally on your Mac.
