What a subscription unlocks
Your saved skill-decay trend
Every diagnostic retake plotted over time, so a real line — not one reading — tells you what’s actually decaying.
Daily adaptive practice
A short, unassisted drill loop that targets your soft spots and spaces reviews so the skill sticks.
The full drill library
Browse and attempt the entire bank by category and difficulty — every attempt counts toward mastery.
Per-skill mastery
Watch each skill climb Cold → Warming → Solid → Sharp, and get warned before one quietly fades.
