Formudrag helps you build, edit, and organize math formulae with drag-and-drop LaTeX tools. Start from built-in templates or your own saved components, replace exact structures directly, and keep a scratchpad nearby while refining the main formula. Use it for class notes, assignments, research drafts, teaching materials, and other academic workflows that need faster formula editing without losing structural control.

Verdict
The clearest difference is in-app purchases: SDAR智能助手 at none against Formudrag's 5. SDAR智能助手 also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (13.0 vs 15.0). Formudrag's advantage is device support (4 vs 2). On price and ads there is nothing between them.
