The csTimer companion you've been missing
Sub-X is not a csTimer replacement. It's the analytics, prediction, and sharing layer csTimer was never designed to be. Time in csTimer (or our built-in timer), import to Sub-X, and finally see your AO100 trend over months.

When should you use Sub-X instead of (or alongside) csTimer?
- You want to see if you're actually improving. csTimer shows the current session; Sub-X shows your AO100 trend across months.
- You want to know when you'll hit your next sub-X. Sub-X projects your milestone ETA based on your improvement rate.
- You want to share your progress. Sub-X gives you a public profile with a custom OG image for Reddit and Discord.
- You cube multiple events. Separate dashboards, targets, and AI coaching for 3×3, 4×4, and 5×5.
