Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- New Workbench page — a dedicated hub for deep equation exploration with interactive rearrangement, algebraic sandbox, dimensional analysis, insights, and historical context all in one place
- Equation Fusion — load two equations sharing a common variable and watch the shared term animate across the screen as the app performs symbolic substitution, making abstract algebra visual and concrete
- Animated equation rearrangement — equations now break into draggable chips that animate algebraic moves step-by-step with fluid motion
- My Calculators — build, save, and share your own custom formula calculators directly in the app, with community submission built in
- Calculator library expanded with AI-assisted building, subject-specific presets, and localised content across 9 languages
- Scientist profiles enriched with more portraits and fuller attribution data; workbench tools, Excel functions, and coding references now available across main languages
