Personal Subs
Save any custom or measured T/S parameter set privately. Keep them for
yourself, publish them to your public profile, or submit them to the shared
community catalog for review. Perfect for measured drivers, DIY builds, or
sub variants that aren't in the official database yet.
Contributor Tier Progression
Level up through Trusted, Contributor, and Curator as you contribute quality
entries. Each tier gives you higher daily submission limits and personal sub
quota bonuses. Every promotion earns an exclusive badge that stays on your
profile forever. A new Progression page shows exactly how close you are to
the next tier.
Quick Access
Long-press any calculator, FAQ, saved design, sub, page, or setting on the
Home page to pin it up top. Drag to reorder. Your most-used tools, one tap
