Native apps for iPhone, iPad, and Windows — no browser version. One account syncs projects across all devices; cloud sync only, solves never leave your device. Pro is purchased per platform: iPhone and iPad share one App Store subscription; Windows Pro is billed separately via Stripe.
Full SPMSM pipeline in your pocket. Quick parameter sweeps, Id/Iq load points, and dq outputs on-device. Pro via App Store — one subscription also covers iPad.
Large canvas for geometry, |B| field maps, and torque waveforms. Ideal for design reviews and client demos. Pro via the same App Store subscription as iPhone.
Native Windows app with the same workflow. Free .exe download; sign in to sync projects. Pro via Stripe unlocks topology, slots, and poles.
Every platform has a free download. One account syncs projects across iPhone, iPad, and Windows. Pro unlocks topology, slot, and pole-pair changes on each platform you pay for — subscriptions are separate and do not cross over.
iPhone + iPad Pro: one App Store subscription ($29.99/mo or $299/yr). Windows Pro: separate Stripe subscription ($99/mo, $999/yr, or $2,999 lifetime).
